This series adds support for the Phytec i.MX8 SoM. It comes with a
minimal i2c EEPROM read helper for the PBL and imports + 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 v4:
- rebased to current next
- actually the same as v3, but send to barebox mailing list
Changes in v3:
- phyboard_polis_rdk_ddr_init():
- introduce PHYTEC_IMX8M_DDR_* for different RAM sizes
- get rid of CONFIG_PHYCORE_IMX8MM_RAM_SIZE_* and build always all
images
- clean up printing of error messages
- lpddr4-timing: adopt to coding style
- Link to v2: https://lore.pengutronix.de/20230606-phytec-som-imx8mm-v2-0-8c9368c8b4f9@xxxxxxxxxxxxxx
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@xxxxxxxxxxxxxx
