Merge patch series "AM62A DWC3: Add support for USB DFU boot in OTG mode"
Siddharth Vadapalli <s-vadapalli@ti.com> says:
Hello,
This series adds support for USB DFU boot on TI's AM62A SoC which has
two instances of DWC3 USB Controllers namely USB0 and USB1. The USB0
instance of the USB Controller supports USB DFU boot:
ROM => tiboot3.bin => tispl.bin => u-boot.img
USB DFU Boot requires the USB Controller to be configured for Gadget
mode of operation. Since the USB0 instance of the DWC3 USB Controller
supports both Host and Gadget modes of operation via the Type-C interface
on the AM62A7-SK board, the device-tree specifies the "dr_mode" as "OTG".
However, there is currently no support for dynamically switching the "mode"
from Host to Gadget and vice-versa with the help of a state-machine.
The OTG mode is treated as a separate mode in itself rather than being
treated as an intermediate stage before assuming the Host/Gadget mode.
Due to this, USB DFU boot via the Type-C interface doesn't work as the
USB Controller hasn't been appropriately configured for Device/Gadget
mode of operation. One option is to change the device-tree to specify
"dr_mode" as "peripheral" and force the controller to assume the Device
role. This will imply that the U-Boot device-tree for AM62A diverges
from its Linux counterpart. Therefore, with the intent of keeping the
device-tree uniform across Linux and U-Boot, and at the same time, in
order to enable USB DFU boot in "OTG" mode with the DWC3 Controller,
the first patch in this series sets the "mode" on the basis of the
caller function, rather than using the "dr_mode" property in the
device-tree. There are only two callers of "dwc3_generic_probe()",
each of which clearly specify the expected mode of configuration.
This will enable both Host and Device mode of operation based on the
command executed by the user, thereby truly supporting "OTG"
functionality when the USB Controller supports it.
The second patch in this series adds USB DFU environment for AM62A,
enabling USB DFU Boot and USB DFU flash on AM62A.
In addition to the patches in this series, the following device-tree
changes will be required to test USB DFU on AM62A (bootph-all property
to be added to ensure that USB Controller is present at all stages
for DFU Boot):
https://gist.github.com/Siddharth-Vadapalli-at-TI/53ba02cb0ff4a09c47e920d08247065f
The above device-tree changes will be made to the Linux device-tree,
which shall ensure that the same shall be a part of U-Boot device-tree
eventually.
The USB DFU config fragments for AM62x have been used for enabling
USB DFU boot on AM62a as follows:
R5 => am62ax_evm_r5_defconfig + am62x_r5_usbdfu.config
A53 => am62ax_evm_a53_defconfig + am62x_a53_usbdfu.config

usb: dwc3-generic: set "mode" based on caller of dwc3_generic_probe()
There are only two callers of "dwc3_generic_probe()", namely:
1. dwc3_generic_peripheral_probe()
2. dwc3_generic_host_probe()
Currently, the "mode" is set based on the device-tree node of the
platform device. Also, the DWC3 core doesn't support updating the "mode"
dynamically at runtime if it is set to "OTG", i.e. "OTG" is treated as a
separate mode in itself, rather than being treated as a mode which should
eventually lead to "host"/"peripheral".
Given that the callers of "dwc3_generic_probe()" clarify the expected
"mode" of the USB Controller, use that "mode" instead of the one
specified in the device-tree. This shall allow the USB Controller to
function both as a "Host" and as a "Peripheral" when the "mode" is "otg"
in the device-tree, based on the caller of "dwc3_generic_probe()".

boot: fdt: Handle already reserved memory in boot_fdt_reserve_region()
The boot_fdt_add_mem_rsv_regions() function can be called twice, e.g.
first time during the board init (as a part of LMB init), and then when
booting the OS with 'booti' command:
That consequently leads to the attempt of reserving the same memory
areas (described in the 'reserved-memory' dts node) in LMB. The
lmb_add_region_flags() returns -EEXIST error code in such cases, but
boot_fdt_reserve_region() handles all negative error codes as a failure
to reserve fdt memory region, printing corresponding error messages,
which are essentially harmless, but misleading. For example, this is the
output of 'booti' command on E850-96 board:
The mentioned false positive error messages are observed starting with
commit 1d9aa4a283da ("lmb: Fix the allocation of overlapping memory
areas with !LMB_NONE"), which removes the check for the already added
memory regions in lmb_add_region_flags(), making it return -1 for
!LMB_NONE cases. Another commit 827dee587b75 ("fdt: lmb: add reserved
regions as no-overwrite") changes flags used for reserving memory in
boot_fdt_add_mem_rsv_regions() from LMB_NONE to LMB_NOOVERWRITE. So
together with the patch mentioned earlier, it makes
lmb_add_region_flags() return -1 when called from
boot_fdt_reserve_region().
Since then, the different patch was implemented, returning -EEXIST error
code in described cases, which is:
lmb: Return -EEXIST in lmb_add_region_flags() if region already added

An attempt to add the already added LMB region using
lmb_add_region_flags() ends up in lmb_addrs_overlap() check, which

otherwise. It makes it impossible for the user of this function to catch
the case when the region is already added and differentiate it from
regular errors. That in turn may lead to incorrect error handling in the
caller code, like reporting misleading errors or interrupting the normal
code path where it could be treated as the normal case. An example is
boot_fdt_reserve_region() function, which might be called twice (e.g.
during board startup in initr_lmb(), and then during 'booti' command
booting the OS), thus trying to reserve exactly the same memory regions
described in the device tree twice, which produces an error message on
second call.
Return -EEXIST error code in case when the added region exists and it's
not LMB_NONE; for LMB_NONE return 0, to conform to unit tests
