[U-Boot,00/10] ARM: clearfog: add run-time board detect

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.

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.

Baruch Siach (10):
  ddr: marvell: a38x: allow board specific clock out setup
  arm: mvebu: clearfog: enable both DDR clocks
  cmd: add sys_eeprom command
  ARM: mvebu: clearfog: add EEPROM devices
  ARM: mvebu: clearfog: add support for EEPROM TLV info
  ARM: mvebu: clearfog: read basic TLV data
  ARM: mvebu: clearfog: print TLV stored product name
  ARM: mvebu: clearfog: run-time selection of DT file
  ARM: mvebu: clearfog: add Clearfog GTR support
  ARM: mvebu: clearfog: add Clearfog Base serdes configuration

Apart from my comments in the patches, please rebase the patchset on
top of current mainline before resubmitting.
