When building this driver for architectures where CMA is not available.
Fixes: 4f2a8f5898ec ("drm: Add ASPEED GFX driver") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Joel Stanley <joel@jms.id.au> --- This fixes the build break.
Another question is if we need to select this at all, as we have a reserved memory region to allocate from. I am not familiar with this area, so advice is welcome.
