      refactor(plat/arm): store UUID as a string, rather than ints · 7d111d99
      David Horstmann authored 
      

NOTE: Breaking change to the way UUIDs are stored in the DT

Currently, UUIDs are stored in the device tree as
sequences of 4 integers. There is a mismatch in endianness
between the way UUIDs are represented in memory and the way
they are parsed from the device tree. As a result, we must either
store the UUIDs in little-endian format in the DT (which means
that they do not match up with their string representations)
or perform endianness conversion after parsing them.

Currently, TF-A chooses the second option, with unwieldy
endianness-conversion taking place after reading a UUID.

To fix this problem, and to make it convenient to copy and
paste UUIDs from other tools, change to store UUIDs in string
format, using a new wrapper function to parse them from the
device tree.

      feat(fdt): introduce wrapper function to read DT UUIDs · d13dbb6f
      David Horstmann authored 
      

TF-A does not have the capability to read UUIDs in string form
from the device tree. This capability is useful for readability,
so add a wrapper function, fdtw_read_uuid() to parse UUIDs from
the DT.
This function should parse a string of the form:

"aabbccdd-eeff-4099-8877-665544332211"

to the byte sequence in memory:

[aa bb cc dd ee ff 40 99 88 77 66 55 44 33 22 11]

      fdts: stm32mp1: add support for the Seeed Odyssey SoM and board · c3c6732f
      Grzegorz Szymaszek authored 
      

Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the
STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a
cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a
4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD
output, and the other available at the MPU’s port PG3. The SoM can be
plugged into a carrier board using its three 70‑pin connectors.

Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in
a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a
microSD card port and various I/O interfaces.

The device tree is based on the DKx boards. TF‑A was successfully tested
on the board with Buildroot 2021.02 and U-Boot 2021.04.

      fdts: stm32mp1: add alternative SDMMC2 pins to the pinctrl · 0e480e0e
      Grzegorz Szymaszek authored 
      

The new pins—PA8, PA9, PE5, and PC7—are described in a new pinctrl node
named “sdmmc2-d47-3”, AKA phandle “sdmmc2_d47_pins_d”. These names are
identical to their Linux kernel counterparts (commit
7af08140979a6e7e12b78c93b8625c8d25b084e2).

      fdts: stm32mp1: add I2C2 pins in the pinctrl · 214b4f9a
      Grzegorz Szymaszek authored 
      

Some STM32MP1‐based boards, like Seeed Studio’s SoM‐STM32MP157C, have
the SoC connected to the PMIC via I2C2 instead of I2C4 (which is used on
the official ST development boards). This commit brings TF‑A one step
closer to boot on such boards.

The pins used, PH4 and PH5, are described in a new pinctrl node named
“i2c2-0”, AKA phandle “i2c2_pins_a”. These names are identical to their
Linux kernel counterparts (commit
7af08140979a6e7e12b78c93b8625c8d25b084e2).
