[ Upstream commit bf296b35489b46780b73b74ad984d06750ed5479 ]
Kernel test robot reported build errors (undefined references)
that didn't make much sense. After reproducing them, there is also
a Kconfig warning that is the root cause of the build errors, so
fix that Kconfig problem.
Fixes this Kconfig warning:
WARNING: unmet direct dependencies detected for CMA
Depends on [n]: MMU [=n]
Selected by [m]:
- DRM_ASPEED_GFX [=m] && HAS_IOMEM [=y] && DRM [=m] && OF [=y] &&
(COMPILE_TEST [=y] || ARCH_ASPEED) && HAVE_DMA_CONTIGUOUS [=y]
and these dependent build errors:
(.text+0x10c8c): undefined reference to `start_isolate_page_range'
microblaze-linux-ld: (.text+0x10f14): undefined reference to
`test_pages_isolated'
microblaze-linux-ld: (.text+0x10fd0): undefined reference to
`undo_isolate_page_range'
Fixes: 76356a966e33 ("drm: aspeed: Clean up Kconfig options")
