The phyCORE-i.MX 93 is available in various variants (e.g. different ram
sizes, eMMC HS400 yes/no). It's eeprom contains information which features
the existing module supports.
Extend the existing board-code to support all the SOM variants. The spl/u-boot
evaluates the eeprom information and enables supported features accordingly.
The resulting spl and u-boot binary is able to boot each phyCORE-i.MX 93 SOM
variant on each carrier board.
Changes in v2:
patch #1:
- remove multiple blank lines
- add update of 1GB ram timings to commit message
patch #2:
- encapsulate handling of feature flag VOLTAGE into own function
- move definition of enum phytec_imx93_ddr_eeprom_code into header file
patch #3:
- just rename imx93-phyboard-segin_defconfig and add needed CONFIGs,
instead of creating an entirely new second defconfig
Don't forget to update the docs "Build U-Boot" chapter mentioning the
new defconfig.
- remove wrong comment from imx93-phyboard-segin-u-boot.dtsi
- improve commit message
