From 441cbd8dace80545db2ac43175ac1c097d96f75c Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 26 Oct 2006 15:38:10 +1000 Subject: [POWERPC] Fix various offb issues This patch fixes a few issues in offb: - A test was inverted causing the palette hack to never work (no device node was passed down to the init function) - Some cards seem to have their assigned-addresses property in a random order, thus we need to try using of_get_pci_address() first, which will fail if it's not a PCI device, and fallback to of_get_address() in that case. of_get_pci_address() properly parsees assigned-addresses to test the BAR number and thus will get it right whatever the order is. - Some cards (like GXT4500) provide a linebytes of 0xffffffff in the device-tree which does no good. This patch handles that by using the screen width when that happens. (Also fixes btext.c while at it). - Add detection of the GXT4500 in addition to the GXT2000 for the palette hacks (we use the same hack, palette is linear in register space at offset 0x6000).
