Hi Baruch,

Newer revisions of SolidRun Clearfog Base/Pro carriers and Armada 388 SOM add
EEPROM storage for board detection. This patch series adds support for reading
EEPROM stored board information, and using it to set RAM training parameters,
serdes configuration, and kernel DT selection.
The information is stored in EEPROM in TLV format defined for the ONIE project.
https://opencomputeproject.github.io/onie/design-spec/hw_requirements.html
This series add the sys_eeprom command from ONIE carried U-Boot patch, with a
number for changes as described in the patch log. The TLV format is unchanged.
This series also adds support for the newly introduced single board, Aramda 385
based Clearfog GTR system. RAM configuration on that system requires both
Armada 38x DDR clocks to be enabled. The first patch in this series adds the
necessary code to allow per-board selection of DDR clock.
Apart from my comments in the patches, please rebase the patchset on
top of current mainline before resubmitting.
Thanks,
Stefan
