The commit bc07851897bd ("board: ti: Pull redundant DDR functions to a
common location and Fixup DDR size when ECC is enabled") broke DRAM
support for the Verdin AM62. This was partially fixed with commit 3f866c47b582 ("board: verdin-am62: add dram_init_banksize"). However,
because fixup_memory_node was not called, the Linux kernel was started
with the wrong memory size on modules with less memory available. This
resulted in boot failures. Fix this issue by calling fixup_memory_node
in the board file.
spl_perform_fixups will be called in the SPL and now sets the correct
memory size in the device tree of U-Boot by calling fixup_memory_node.
U-Boot will then adjust the memory sizes of Linux during bootm/booti in
fdt_fixup_memory_banks. This chain ensures that U-Boot and Linux only
use RAM that is actually available.

The cause is that "serial,nc" forced the console subsystem to
initialize the ethernet driver before ethernet subsystem
initialization (console_init_r() is called before initr_net()).
During the mtk_eth driver initialization, mdio_register() will be
called, and miiphy_get_dev_by_name() will then be called.
The miiphy_get_dev_by_name() will check the list "mii_devs" to see
if the passed device name exists. However the mii_devs is defined
without initialization:
> static struct list_head mii_devs;
and the actual initialization is done in the following chain:
initr_net -> eth_initialize -> eth_common_init -> miiphy_init
Since initr_net() hasn't be called, iterating over the mii_devs
will access to physical address 0 (mii_devs.next == NULL) and will
cause the crash.
The fix is to define mii_devs using:
> static LIST_HEAD(mii_devs);
As the "current_mii" is defined as a static variable, it will
always be NULL in board_r stage and initializing it will NULL is
unnecessary. So the entire miiphy_init() can be remove.

When an error is detected in the TSEC receive path, the driver currently

section 6.2.4 Configure partitions indicates that EXT_CSD SEC_COUNT
should not be used to determine device size, and instead device size
should be calculated from C_SIZE and C_SIZE_MULT.
This is not exactly accurate, the 2 GiB limit is not a hard line,
there are eMMC devices which are smaller than 2 GiB and still
require device size to be determined from EXT_CSD SEC_COUNT. The
hard line is instead OCR HCS bit, which indicates whether the device
is byte or sector addressed, the former applies to most devices
below 2 GiB, and the later applies mostly to devices above 2 GiB.
However, there are a couple of devices which are smaller than 2 GiB
and still set the OCR HCS bit to indicate they are sector addressed,
and therefore the size calculation for those devices should also
use EXT_CSD SEC_COUNT . Use mmc->high_capacity flag to discern the
devices instead of arbitrary 2 GiB limit. The mmc->high_capacity flag
reflects the OCR HCS bit state.

image: Add support for starting TFA BL31 as fitImage loadables
Add support for starting TFA from U-Boot running in EL3 as part of
fitImage boot, so the user can start U-Boot in the highest privilege
level on the platform, bundle TFA, Linux, DT into a single fitImage
and boot such a bundle as a whole.
There are two main benefits of this approach. First is the ability
to run U-Boot in EL3, where it has unrestricted access to the entire
system and can act as a useful debug tool, as it was always intended
to be used. Second is the ability to easily and safely update of any
component in the fitImage, be it TFA, Linux or DT.
The boot process is similar to regular Linux with DT fitImage boot
process, except the TFA has to be bundled into the fitImage. For the
bundling instructions, see below. The TFA is started as a 'loadables'
with custom U_BOOT_FIT_LOADABLE_HANDLER and armv8_switch_to_el2_prep()
handling implemented in board code, and performing the handoff and
boot in case the TFA was loaded.
The loadables handler is optional and meant to set up any sort of
handoff structures used by the TFA BL31 or perform any other setup
that is needed by the blob. The custom armv8_switch_to_el2_prep()
has to implement the jump to TFA BL31 with return to U-Boot just
before booting the Linux kernel.

arm64: Add late jump to kernel board hook
Add empty weak assembler function armv8_switch_to_el2_prep() which is
jumped to just before U-Boot determines which EL it is running in and
decides which path to take to boot the Linux kernel.
This weak function is meant to be used by architecture specific code
to implement jump to a firmware blob, which then returns right past
this weak function and continues execution of U-Boot code which then
boots the Linux kernel. One example of such use case is when U-Boot
jump tp TFA BL31, which switches from EL3 to EL2 and then returns to
U-Boot code newly running in EL2 and starts the Linux kernel.
The weak function is called with caches already disabled and DM shut
down. Any preparatory work or even loading of more data must be done
in board_prep_linux(), this hook is meant only for the final jump to
the firmware and return to U-Boot before booting Linux.

mbedtls/external: remove broken git submodule
When we squash imported mbedtls, the git submodule "framework" was
preserved in the commit. However, U-Boot itself does not use git
submodule, and provides no .gitmodules file to specify the submodule
repository.
This is normally not an issue when cloning U-Boot repository. However,
when U-Boot is imported as a submodule, this will break git option
`--recurse-submodules` as it fails to resolve "framework".
As we do not use the submodule, remove it to unbreak existing workflows.

board: transformer-t30: fix model detection
PCBID1 seems to be high not only on TF600T, but on TF700T as well,
that caused boot failure for TF700T. Switching PCBID1 to PCBID7
should fix this issue.

net-lwip:
* Fix incorrect selection of ethernet device on boards having more than
one
* Fix TFTP option processing
* Make the WGET_HTTPS Kconfig symbol depend on DM_RNG
net/lwip/wget.c/mbedtls_hardware_poll() is calling dm_rng_read() but
dependency is not recorded anywhere that's why depend on DM_RNG
when WGET_HTTPS is used.

Find_option() is used to retrieve the block size value in an option
acknowledgment in response to a request containing a block size option
according to RFC2348.
The format of an OACK response is described in RFC2347 as
The current implementation of find_option() only works if
* blksize is the first option
* lwip_strnstr() ignores the length parameter,
i.e. is implemented via strstr()
The OACK messages starts with 0x00 0x06. If 'blksize' is the first option,
strstr() reports a match when the first parameter points to 0x06. Adding
the string length of 'blksize' plus 2 to the location of the 0x06 byte
points to the value.
Find_option() would report a match for option 'blksize' if the response
contained an option called 'foo_blksize_bar'. In this case find_option()
would return 'bar' as the value string.
If 'blksize' were the second option, find_option() would return a pointer
to the second character of the value string.
Furthermore find_option() does not detect if the value string is NUL
terminated. This may lead to a buffer overrun.
Provide an implementation that correctly steps from option to option.

net: lwip: move eth_init() out of new_netif()
Move the initialization of the ethernet devices out of the new_netif()
function. Indeed, new_netif() accepts a struct device argument, which
is expected to be valid and active. The activation and selection of
this device are achieved by eth_init() (on first time the network
stack is used) and eth_set_current(). This is what takes care of the
ethrotate and ethact environment variables. Therefore, move these calls
to a new function: net_lwip_set_current(), and use it whenever a
net-lwip command is run.
This patch hopefully fixes the incorrect net-lwip behavior observed on
boards with multiple ethernet interfaces [1].
Tested on an i.MX8MPlus EVK equipped wih two ethernet ports. The dhcp
command succeeds whether the cable is plugged into the first or second
port.
