[PATCH v2 0/3] ARM: i.MX8MM: add Phytec i.MX8 SoM support

[Marc Kleine-Budde]

This series adds support for the Phytec i.MX8 SoM. It a minimal i2c
EEPROM read helper for the PBL and import + adopts the Phytec SOM
detection from u-boot. The Phytec SOM detection reads and parses the
EEPROM on the SOM to figure out the size of the populated RAM.

Changes in v2:
- make several pointers to "struct phytec_eeprom" const
- phytec_print_som_info(): use printf() instead of pr_cont()
- let phytec_imx8m_detect() return int instead of u8
- fix typo in phytec_get_imx8m_spi()'s comment
- rename struct phytec_api0_data::pad -> __pad
- move include/phytec-som-* to include/boards/phytec
- Link to v1: https://lore.barebox.org/20230606-phytec-som-imx8mm-v1-0-b9c2bf70b766@pengutronix.de
