Subject: imx8: cpu: restrict checking ROM passover info for revA
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9382f73bb036b36f08675f3eba3072c47a1e602f;p=u-boot.git

imx8: cpu: restrict checking ROM passover info for revA

Passover info only for revA.

move get_cpu_rev out of CONFIG_CPU to avoid build failure when using
get_cpu_rev in SPL.
Add a CONFIG_SPL_BUILD for passover usage, no need to execute it again
in normal U-Boot stage. Also if still checking passover info in normal
U-Boot stage, need to make the passover code executed after
arch_cpu_init_dm.
So to make it easy and clean, only execute the code for SPL stage.
