x86: Allow adding non-aligned size for MTRR At present mtrr_add_request() requires that the size is a power of two. This is too limiting for machines with 4GB (or more) of RAM, since they often must take account of a memory hole at 3GB. Update the function to automatically deal with an unaligned size, using more MTRRs as required. The algorithm is taken from coreboot commit 60bce10750 Signed-off-by: Simon Glass <sjg@chromium.org>
