cm-t54 Eth MAC address is stored in onboard EEPROM.
Add EEPROM support and setup stored Eth MAC address.
If EEPROM does not contain a valid MAC, then generate it from the
processor ID code (reference code is taken from OMAP5 uEvm board file).
Modify Device Tree blob MAC address field with retrieved data.

Hi Dmitry,
I took a good look at the patch and there's a problem.

This appears to be broken for SPL in case that CONFIG_SYS_MMC_ENV_DEV is not 0.
SPL hardcoded dev to 0, while mmc_switch_part is implicitly operating on
CONFIG_SYS_MMC_ENV_DEV.
Please rework it so that the SPL case is unaffected.

Exactly as it was broken before the patch, right?

This patch does not change the behavior and its purpose
is not fixing the current code.
The bug describe can be fixed by later patch and possibly
will require additional review and testing.
Given that this patch does not change the behavior, can it be accepted
please ?
