[PARISC] Truncate overlapping PAT PDC reported ranges
Deal with overlapping LBA MMIO resources, rp3440 PDC BUG: PDC reports lmmio range for the last rope that overlaps with the CPU HPA. Console output was: ... Found devices: 1. Storm Peak Fast at 0xfffffffffe798000 [152] { 0, 0x0, 0x889, 0x00004 } 2. Storm Peak Fast at 0xfffffffffe799000 [153] { 0, 0x0, 0x889, 0x00004 } ... FAILED: lba_fixup_bus() request for lmmio_space [fffffffff0000000/fffffffffecffffe] Output is now: LBA: Truncating lmmio_space [fffffffff0000000/fffffffffecffffe] to [fffffffff0000000,fffffffffe797fff] My only concern with this patch is how C8000 (PAT PDC) will report elmmio ranges when a gfx card is installed. I'll have to test this another day.
