Subject: arm: imx: cx9020: remove usage of mx53_dram_size
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a75a3ef3059bef48529d5bede93da671ea0376bb;p=u-boot.git
arm: imx: cx9020: 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().
However multiple calls are better than undefined behavior...
