There is no need to reread the EEPROM multiple times in different stages
to detect the RAM size. We can do this once at an early stage and let
higher stages decode memory nodes using fdtdec.
Make sure to pass fixup memory nodes before passing to u-boot stage.

Use content of EEPROM to detect the actual RAM size and adjust
DDR timings, size and banks accordingly.
Also enable the SoM detection per default in the defconfigs.

Environment handling code can be reused across all our K3 based SoMs.
Instead of adding the same code for every new SoM, move it to a common
board.c file.

Daniel Schultz <d.schultz@phytec.de> says:
This patch series extends PHYTEC's SOM detection by minor
fixes, a generic helper function and a new valid flag.
Moreover, it adds a module to provide access to the SOM
detection for our TI AM6 products.
Add all functions to read each SOM option from the EEPROM
image and detect whether it's the correct product for this
image.

Also, introduce a "boot" variable that represents the current boot
device and can be used by scripts.
