380b8f307c powerpc/c29xpcie: Getting DDR SPD image from 16-bit sub-address EEPROM
Currently, there is only one EEPROM on c29xpcie board which is AT24C1024.
We program the SPD data at beginning of the AT24C1024.But the AT24C1024
has a 16-bit sub-address mode. This patch is tomake it work when getting
SPD in a 16-bit sub-address EEPROM.

5614e71b49 Driver/DDR: Moving Freescale DDR driver to a common driver
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs.
The similar DDR controllers will be used for ARM-based SoCs.

9c25ee6d3a powerpc/c29xpcie: add DDR ECC on off config setting
c29xpcie REV_A board DDR ECC chip has bad impedance in hardware,
force that kind of board to be DDR ECC off when booting.
Other version board config ECC on/off by hwconfig=fsl_ddr:ecc=on
in uboot enviroment.

0dd38a35f4 powerpc: Fix CamelCase warnings in DDR related code
Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h
has various parameters with embedded acronyms capitalized that trigger the CamelCase
warning in checkpatch.pl

Convert those variable names to smallcase naming convention and modify all files
which are using these structures with modified structures.
