Global variables are not available during board_init_f().
The i.MX53 boards m53evk, mx53cx9020 and mx53loco are using the exact
same dram initialization code, which uses
'static uint32_t mx53_dram_size[2];' in dram_init(),
dram_init_banksize() and get_effective_memsize() to avoid multiple
calls to get_ram_size().

This series replaces the static variable with multiple calls to
get_ram_size() and moves the shared code into arch/arm/mach-imx/mx5/.

The first patch fixes cx9020. The next patch moves that code to a common
place to be reused by m53evk and mx53loco with the next patches.

Changes in v2:
- move dram initialization into common location
- reuse fixed dram initialization for m53evk and mx53loco
