Modified: trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/northbridge.c Log: Fix the resource end in amdk8/northbridge.c.
Without this bugfix, the resource for the PCI/ISA video memory at 0xa0000 - 0xbffff is too big, i.e. it goes up to 0xcffff instead of just 0xbffff as it should.
Here's the diff from two runs of the tool from http://www.linuxbios.org/pipermail/linuxbios/2007-June/022449.html on the MSI MS-7260 (K9N Neo), with and without the bugfix. After applying, the resource size is correct again.
