[PATCH 3/4] ARM: davinci: DA8xx+DMx combined kernels need PATCH_PHYS_VIRT
From: Arnd Bergmann
Date: Mon Feb 01 2016 - 15:36:41 EST
We already forbid that combination when AUTO_ZRELADDR is disabled,
for the same reason that the two have their RAM at different
physical addresses as seen from the CPU.
This does the same change for PATCH_PHYS_VIRT: if you disable
either of the options, Kconfig now enforces that you have to
pick one or the other SoC family.
