[U-Boot] [PATCH] powerpc: Fix CamelCase checkpatch warning in DDR related code
Priyanka Jain

Thu Aug 29 08:50:31 CEST 2013
Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h
has various parameters with camelcase naming conventions due to which code checkpatch
script generates "WARNING: Avoid CamelCase".
Convert those variable names to smallcase naming convention and modify all files
which are using these structures with modified structures.
