This is because the u3_ht pci ops silently accept offsets greater than 255 but use only the 8 least significant bits, which means reading at offset 0x100 gets the data at offset 0x0, and causes confusion for lspci. Reject accesses to configuration space offsets greater than 255. Signed-off-by: Nathan Lynch Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
