[PATCH v3 0/3] board: toradex: add verdin am62 support

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler at toradex.com>


This series adds initial support for the Toradex Verdin AM62 SoM [1].
The first commit adds resp. PID4 to the ConfigBlock, the second one
fixes an early clocking issue confirmed to be a weird bug in TI's
scripting. And last but not least support for the Toradex Verdin AM62
is added.

Please note that this series is based on Emanuele's recent work on
get_ram_size() [2] and the addition of the 0070 verdin i.mx 8m plus quad
sku [3].

Changes in v3:
- Add Verdin AM62 launch configuration SKUs as well.
- Integrate our recent find of CTRL_SLEEP_MOCI# needing to be driven
  from A53 SPL as it may be used to control some power-rails on the
  carrier board. E.g. on the Yavia carrier board it is needed to power
  the I2C EEPROM on the carrier board.
- Improve boot environment in R5 SPL vs. A53.
- Integrate launch configuration SKUs to Wi-Fi handling.
- Re-sync device trees from Linux kernel v6.5-rc1.
- Add warning if memory is less than expected.

Changes in v2:
- Add Bryan's reviewed-by tag. Thanks!
- Use 1.2 GHz rather than 1.25 GHz A53 clock as on the EVM/SK.
- Also add power-domain 166 as on the EVM/SK.
- Get rid of main_bcdma and main_pktdma as not required in R5 SPL.
- Get rid of all bootph-pre-ram in Ethernet and SDHC1 aka SD card
  related pinctrls as not required in any SPL.
- Enable CONFIG_TI_SECURE_DEVICE by default as Non-HS devices will
  continue to boot due to runtime device type detection.
- Disable FAT and SPI support as not required in R5 SPL.
- Also enable CONFIG_SPL_MMC_HS200_SUPPORT in R5 SPL.
- Enable CONFIG_LEGACY_IMAGE_FORMAT to allow sourcing unsigned script
  images e.g. like our current boot scripts.
- Increase CONFIG_SYS_BOOTM_LEN to 64 MB to allow booting bigger
  compressed images as e.g. in the Toradex Easy Installer case.
- Change memory configurations to operate at temperatures of up to 95
  degrees celsius.
- Increase CONFIG_SYS_MAXARGS from default 16 to 64.
- Enable CONFIG_CMD_REMOTEPROC, CONFIG_SPL_DM_GPIO_LOOKUP_LABEL and
  CONFIG_SPL_I2C_EEPROM.
- For R5 SPL increase CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN to 0x140000,
  enable CONFIG_SPL_I2C, CONFIG_DM_I2C and CONFIG_SYS_I2C_OMAP24XX and
  savedefconfig got rid of CONFIG_SPL_FIT_IMAGE_POST_PROCESS.
