There was a dirty hack for Intel platforms that read TOLUD register to determine the boundary between MMIO and DRAM. It caused problems on AMD platforms such as apu2, which does not have TOLUD register. As a result, regions which held reserved memory were incorrectly reported as RAM buffers or RAM itself and the OS allocated DMA there. It could be observed with many IO_PAGE_FAULTs occurring in the OS. See: Dasharo/dasharo-issues#1134 Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com>
