Subject: ddr: altera: Drop custom dram_bank_mmu_setup() on Arria10
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=93a8ed868583460ab9f3796fdc92f4713bf759a9;p=u-boot

ddr: altera: Drop custom dram_bank_mmu_setup() on Arria10

This function was never used in SPL and the default implementation of
dram_bank_mmu_setup() does the same thing. The only difference is the
part which configures OCRAM as cachable, which doesn't really work as
it covers more than the OCRAM.
