amd/stoneyridge: Remove fixme.c
Move the two functions in fixme.c to places where they make more sense. Coincidentally fix the todo in amd_initcpuio() and use bsp_topmem() instead of explicitely reading the MSR. BUG=b:62241048 Change-Id: Ica80b92f48788314ad290ccf72e6847fb6d039c3 Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-on: https://review.coreboot.org/22297 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
