Subject: [POWERPC] 85xx: Cleaning up machine probing
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6936c62571d8dc580725775b628ee73d2ac97b6f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[POWERPC] 85xx: Cleaning up machine probing

Cleaned up the probing functionality to be more consistent across all 85xx
boards and actually check to see if we should be running on a given board.
