[U-Boot] [PATCH v2 0/3] Add sdram capacity auto detect for rk3288

The rk3288 spl size is very close to 32KB while the rk3288 bootrom
has the limitation of maximum size of SPL is 32KB. After apply this
patch, the SPL size will exceed 32KB if we do not enable macro
CONFIG_ROCKCHIP_SPL_BACK_TO_BROM.

I think this patch is usful and should be go upstream other than the
size issue.

This patch has test with 2GB DDR3 and 2GB/4GB LPDDR3.

V2 add patch to clean some source code size for some rk3288 board to
make the SPL size in the 32KB limitation.


Changes in v2:
- update code for OF_PLATDATA enabled
- bug fix for ddrconfig

  rk3288: sdram: auto-detect the capacity
