[U-Boot] [PATCH 0/6] ARM: DRA7: Add support for RevH evm

[U-Boot] [PATCH 0/6] ARM: DRA7: Add support for RevH evm

[Lokesh Vutla]

DRA74-evm RevH and later versions uses 4GB DDR and populates this info
in EEPROM. This series reads EEPROM and populates emif settings for 4GB ddr.
If eeprom is not available or evm revision is < H, then it fall backs to
default emif settings.

This series depends on the ti common eeprom driver series posted recently.

[U-Boot] [PATCH 1/6] ti: common: dra7: Add standard access for board description EEPROM

[Lokesh Vutla]

DRA7 EVM revH and later EVMs have EEPROM populated that can contain board
description information such as name, revision, DDR definition, etc. Adding
support for this EEPROM format.

[U-Boot] [PATCH 3/6] ARM: DRA7: Move emif settings to board specific files

[Lokesh Vutla]

The newer versions of DRA7 boards has EEPROM populated with DDR
size specified in it. Moving DRA7 specific emif related settings
to board files so that emif settings can be identified based on EEPROM.

[U-Boot] [PATCH 4/6] ARM: DRA7: EMIF: Add 4GB DDR settings

[Lokesh Vutla]

The REVH and later versions of DRA7-evm uses MICRON MT41K512M16HA-125 memory
chips which is of size 4GB(2GB on EMIF1 and 2GB on EMIF2). Add support for the
same.

This needs to be either folded into 4/6 or re-ordered to not break
bisectability.

[U-Boot] [PATCH 6/6] ARM: DRA7-evm: Update memory info in banks

[Lokesh Vutla]

Updating the memory banks properly so that DT is populated accordingly.
And updating this only after DDR is properly detected by eeprom, so that
git bisect is still maintained.
