Subject: ARM: zynq: Enable DM for CFI NOR flash
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f7375aff959d9d04bcbd2ac7443e62c450716b43;p=u-boot.git

ARM: zynq: Enable DM for CFI NOR flash

With multi defconfig NOR flash information about NOR should be taken from
DT that's why there is no reason to specify address and sizes via fixed
config.
