Subject: powerpc/32: Remove RELOCATABLE_PPC32
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27d1149667352772240655b65372a4294f992ea7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/32: Remove RELOCATABLE_PPC32

It is seldom used in the kernel code and can be easily replaced by
either RELOCATABLE or PPC32. So there is no reason to keep a separate
kernel option for this.
