Subject: arm: imx: m53evk: remove usage of mx53_dram_size
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9d9baacb90492e1a6dc4f88732f6641163aa9c12;p=u-boot.git

arm: imx: m53evk: remove usage of mx53_dram_size

Static variables are not available during board_init_f().
'static uint32_t mx53_dram_size[2];' was used in board specific
dram_init(), dram_init_banksize() and get_effective_memsize() to avoid
multiple calls to get_ram_size().

Reused dram initialization functions from arch/arm/mach-imx/mx5/mx53_dram.c
