[PATCH v5 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. PID4s 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.

Azure CI all passed [2]. Thanks!

Changes in v5:
- Fix doc/board/toradex/verdin-am62.rst title underline being too short.
- Add verdin-am62 to doc/board/toradex/index.rst.
Thanks to Emanuele having run this series on the azure CI to find out.
- Update U-Boot output in doc/board/toradex/verdin-am62.rst to latest.
- State that the device trees were taken straight from Linux v6.5-rc1.
- Remove k3-am625-verdin-wifi-dev-binman.dtsi include from r5 dts.
- Remove memory@ and reserved-memory nodes.
- Simplify sa_secproxy and esm nodes.
- Get rid of ifdef zeros around usb stuff in device trees.
- Re-work doc/board/toradex/verdin-am62.rst in a more re-usable way.
Thanks to Nishanth for pointing those differences out as compared to
arch/arm/dts/k3-am625-r5-sk.dts and his suggestions on the rst stuff.

Changes in v4:
- Re-based on top of master with recent binman integration, mac_efuse,
  cpsw-phy-sel and mdio clean-up and dtsi bump from linux v6.5-rc1.
- Verdin AM62 binman enablement and further clean-up after re-base.
- Removed all ifdefs from DTs now with bumped Linux dtsi.
- Avoid relocated U-Boot and DT reserved-memory clash.
- Enable of_system_setup.

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.
