mach-k3: add dynamic mmu fixups for SPL stage
On platforms with spl splash support i.e CONFIG_VIDEO=y, the top of DDR
is reserved for the framebuffer.
The size for the framebuffer is computed at runtime by video_reserve.
During the MMU configuration an entry corresponding to the framebuffer
should be dynamically created to properly map the required space for the
framebuffer.
Therefore this patch adds k3_spl_mem_map_init which adds the required
MMU entry by querying the gd after the framebuffer size has been
computed in spl_reserve_video_from_ram_top.
For non VIDEO=y platforms, the added k3_spl_mem_map_init function gets
optimized out of the final binary so overall, the spl size is not
impacted[1].

mach-k3: add runtime memory carveouts for MMU table
In u-boot we only provide a single MMU table for all k3 platforms,
this does not scale for devices with reserved memory outside the range
0x9e780000 - 0xa0000000 or for devices with < 2GiB of memory (eg
am62-SIP with 512MiB of RAM).
To properly configure the MMU on various k3 platforms, the
reserved-memory regions need to be queried at runtime from the
device-tree and the MMU table should be updated accordingly.
This patch adds the required fixups to the MMU table (during proper
U-boot stage) by marking the reserved regions as non cacheable and
keeping the remaining area as cacheable.
For the A-core SPL, the 128MiB region starting from SPL_TEXT_BASE
is marked as cacheable i.e 0x80080000 to 0x88080000.
The 128MiB size is chosen to allow for future use cases such as falcon
boot from the A-Core SPL which would require loading kernel image from
the SPL stage. This change also ensures the reserved memory regions that
all exist past 0x88080000 are non cacheable preventing speculative
accesses to those addresses.

mkimage: do a rough estimate for the size needed for hashes/signatures
Background:
I have several customers that will be using a certain remote signing
service for signing their images, in order that the private keys are
never exposed outside that company's secure servers. This is done via
a pkcs#11 interface that talks to the remote signing server, and all
of that works quite well.
However, the way this particular signing service works is that one
must upfront create a "signing session", where one indicates which
keys one will use and, importantly, how many times each key will (may)
be used. Then, depending on the keys requested and the customer's
configuration, one or more humans must authorize that signing session
So for example, if official release keys are to be used, maybe two
different people from upper management must authorize, while if
development keys are requested, the developer himself can authorize
the session.
Once authorized, the requester receives a token that must then be used
for signing via one of the keys associated to that session.
I have that integrated in Yocto in a way that when a CI starts a BSP
build, it automatically works out which keys will be needed (e.g. one
for signing U-Boot, another for signing a kernel FIT image) based on
bitbake metadata, requests an appropriate signing session, and the
appropriate people are then notified and can then look at the details
of that CI pipeline and confirm that it is legitimate.
The problem:
The way mkimage does FIT image signing means that the remote server
can be asked to perform a signature an unbounded number of times, or
at least a number of times that cannot be determined upfront. This
means that currently, I need to artificially say that a kernel key
will be used, say, 10 times, even when only a single FIT image with
just one configuration node is created.
Part of the security model is that once the number of signings using a
given key has been depleted, the authorization token becomes useless
even if somehow leaked from the CI - and _if_ it is leaked/compromised
and abused before the CI has gotten around to do its signings, the
build will then fail with a clear indication of the
compromise. Clearly, having to specify a "high enough" expected use
count is counter to that part of the security model, because it will
inevitably leave some allowed uses behind.
While not perfect, we can give a reasonable estimate of an upper bound
on the necessary extra size by simply counting the number of hash and
signature nodes in the FIT image.
As indicated in the comments, one could probably make it even more
precise, and if there would ever be signatures larger than 512 bytes,
probably one would have to do that. But this works well enough in
practice for now, and is in fact an improvement in the normal case:
Currently, starting with size_inc of 0 is guaranteed to fail, so we
always enter the loop at least twice, even when not doing any signing
but merely filling hash values.
Just in case I've missed anything, keep the loop incrementing 1024
bytes at a time, and also, in case the estimate turns out to be over
64K, ensure that we do at least one attempt by changing to a do-while
loop.
With a little debug printf, creating a FIT image with three
configuration nodes previously resulted in
corresponding to 1+2+3+3 signatures requested (so while the loop count
is roughly linear in the number of config nodes, the number of
signings is quadratic).
Update a binman test case accordingly: With the previous behaviour,
mkimage would try size_inc=0 and then size_inc=1024 and then
succeed. With this patch, we first try, and succeed, with 4*128=512
due to the four hash nodes (and no signature nodes) in 161_fit.dts, so
the image ends up 512 bytes smaller.

binman: rework dropping absent entries from packaged image
When blobs are absent and are marked as optional, they can be safely
dropped from the binman tree. Use the drop_absent function for that.
Rename drop_absent to drop_absent_optional as we do not want to drop any
entries that are absent; they should be reported by binman as errors
when they are missing.
We also reorder the processing of the image the following:
- We call the CheckForProblems function before the image is built.
- We drop entries after we checked for problems with the image.
This is okay because CheckForProblems does not look at the file we have
written but rather queries the data structure (image) built with binman.
This also allows us to get all error and warning messages that we want
to report while avoiding putting missing optional entries in the final
image.
As only the blobs are dropped, the sections still remain in the
assembled image. Thus add them to the expected test case checks where
necessary.
In addition, a rework of testPackTeeOsOptional test case is necessary.
The test did not really do what it was supposed to. The description said
that optional binary is tested, but the binary is not marked as
optional. Further, the tee.elf file, when included in the image
properly, also shows up in the image data. This must be added as well.

- fdt_get_key() to parse the curve and coordinates from the FDT
- read_key_from_fdt() to convert the parsed values into an OpenSSL EC_KEY
- load_key_from_fdt() to support loading keys using required_keynode,
keyname hint, or fallback to scanning all subnodes under "/signature".
If "info->fdt_blob" is provided, the key is loaded from the FDT. Otherwise,
the code falls back to loading a PEM-formatted key from file as before.
This allows for ECDSA signature verification where the public key is
embedded in the FIT image device tree, useful for systems that require
signature validation without external files.

Merge patch series "lmb: use a single API for all allocations"
Sughosh Ganu <sughosh.ganu@linaro.org> says:
The LMB module has a bunch for API's which are used for allocating
memory. There are a couple of API's for requesting memory, and two
more for reserving regions of memory. Replace these different API's
with a single one, lmb_alloc_mem(). The type of allocation to be made
is specified through one of the parameters to the function.
Additionally, the two API's for reserving regions of memory,
lmb_reserve() and lmb_alloc_addr() are the same with one
difference. One can reserve any memory region with lmb_reserve(),
while lmb_alloc_addr() actually checks that the memory region being
requested is part of the LMB memory map. Reserving memory that is not
part of the LMB memory map is pretty futile -- the allocation
functions do not allocate memory which has not been added to the LMB
memory map.
This series also removes the functionality allowing for reserving
memory regions outside the LMB memory map. Any request for reserving a
region of memory outside the LMB memory map now returns an -EINVAL
error.
Certain places in the common code using the LMB API's were not
checking the return value of the functions. Checks have been added for
them. There are some calls being made from the architecture/platform
specific code which too do not check the return value. Those have been
kept the same, as I do not have the platform with me to check if it
causes any issues on those platforms.
In addition, there is a patch which refactors code in
lmb_overlaps_region() and lmb_can_reserve_region() so that both
functionalities can be put in a single function, lmb_overlap_checks().
Finally, a new patch has been added which checks the return value of
the lmb allocation function before copying the device-tree to the
allocated address.

mach-snapdragon: add a check before copying FDT to fdt_addr_r
The board_late_init() function allocates memory for a bunch of
environment variables, including fdt_addr_r. The device-tree then gets
copied to the memory pointed to by fdt_addr_r. However, the memory
allocation request can fail, in which case the address that is being
written to would not be allocated. Add a check that the memory
allocation has succeeded before copying the device-tree.

lmb: use a single function to check for allocation and reservation requests
The functions that handle allocation requests check if a region of
memory overlaps with a used region. This is done through
lmb_overlaps_region(). Similar checks are done for reservation
requests made to the LMB module, where the caller asks specifically
for a particular region of memory. These checks are being done through
lmb_can_reserve_region().
There are subtle differences in the checking needed for allocation
requests, as against reservation requests. In the former, it is only
needed to be checked if a region is overlapping with an existing
used region, and return as soon as an overlap is found. For
reservation request checks, because U-Boot allows for re-use of in-use
regions with a particular memory attribute, this check has to iterate
through all the regions that might overlap with the requested region,
and then check that the necessary conditions are met to allow for the
overlap.
Combine these two checks in a single function, lmb_overlap_checks() as
both lmb_overlaps_region() and lmb_can_reserve_region() are pretty
similar otherwise.

There currently are two API's for requesting memory from the LMB

lmb_alloc_mem() for both types of allocation requests.

There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and

for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.
Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.
There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

This PR introduces 3 new platforms, two from the new Dragonwing IQx
series (QCS615 and QCS8300) as well as the IPQ5424.
Additionally:
* Support for booting downstream Android boot images on some phones is
added
* Capsule update support is expanded to be more generic, determining
which partition U-Boot was flashed to automatically and supporting
many more boards.
* Minor capsule update bugs are fixed
* A watchdog driver is added and gets timeout support
* Autoboot now requires pressing "space" specifically to stop booting as
a workaround for some boards getting rogue key presses which would
cause autoboot to fail
* Documentation is added for the Dragonwing boards
* The RB1/2 now use USB gadget mode rather than host
* A bug is fixed where GPIO reads could return incorrect values
We can now correctly identify which partition U-Boot is flashed to
between uefi, xbl, and boot (including A/B support) so enable capsule
update support for all boards.
Calling scsi_scan() results in all the block devices (and EFI block
devices) being destroyed and re-created. This breaks the EFI filesystem
drivers during capsule update.
Remove the call, since boards really should be calling scsi_scan()
themselves during board_init().
mach-snapdragon: CapsuleUpdate: support all boot methods
Expand capsule update support to correctly identify which partition
U-Boot is flashed to (between xbl, uefi, and boot including A/B
variants).
Use qcom_boot_source to determine if we were chainloaded from ABL,
meaning U-Boot is on the boot partition, otherwise we assume uefi if
it's available, finally leaving the xbl partition.
Set a different fw_name based on the target partition to prevent GUID
collisions, since a board may support U-Boot flashed to boot or XBL we
need to differentiate them since the U-Boot binary must be built
differently.
Keep track of whether we were loaded via ABL or if U-Boot is running as
a first-stage bootloader.
For now we set this based on if we have a valid external FDT or not,
since it isn't possible to chainload U-Boot from ABL without there being
an external FDT.
This will be used to inform the capsule update logic which partition
U-Boot is flashed to.

In order to unzipped kernel from androidboot img, extra memory for

That can balance with memory constrain soc and android usecase.
Some androidboot image have invalid kernel/ramdisk load addr,

There is a concern on exposing the whole memory to image loading is
dangerous. Also, since it's not always possible to change the load

we need a way to use kernel_addr_r and ramdisk_addr_r.
