Lubomir Rintel b2fa1b2494 vx900: skip remap of high memory ranges if unnecessary ... If the DRAM does *not* actually overlap the PCI space, the remap code notices it is the case, but for some reason proceeds with the remapping, attempting to remap a negatively sized chunk. Bummer. With a single 1024M (two ranks of 512M) module: Nothing to remap Mem remapping enabled Remapstart 5120(MB) Remapend 6144(MB) Top of RAM 1024MB New top of RAM 2560MB Wrote remap map a0101 Mem remapping enabled Remapstart 4096(MB) Remapend 2560(MB) New top of memory is at 2560MB Needless to say, subsequent ram_resource() ruins the memory map for the OS -- Linux won't boot without a mem= argument and memtest quickly. TEST=memtest and Linux boot on HP t5550 with 1024M of memory Change-Id: Ic221723a26c5d1a03bf34c7722b0abe115f456ba Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Reviewed-on: https://review.coreboot.org/22271 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>		2018-01-15 00:47:27 +00:00
