2007-12-11[POWERPC] Merge pci_process_bridge_OF_ranges()Benjamin Herrenschmidt
This merges the 32-bit and 64-bit implementations of pci_process_bridge_OF_ranges(). The new function is cleaner than both the old ones, and supports 64 bits ranges on ppc32 which is necessary for the 4xx port. It also adds some better (hopefully) output to the kernel log which should help diagnose problems and makes better use of existing OF parsing helpers (avoiding a few bugs of both implementations along the way). There are still a few unfortunate ifdef's but there is no way around these for now at least not until some other bits of the PCI code are made common.

2007-12-11[POWERPC] Make isa_mem_base common to 32 and 64 bitsBenjamin Herrenschmidt
This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits only). This avoids a few ifdef's in later patches and potentially can allow support for VGA text mode on 64 bits powerpc.

2007-12-11[POWERPC] Kill flatdevtree.cDavid Gibson
Now that earlier patches have switched the bootwrapper to using libfdt for device tree manipulation, this patch removes the now unused flatdevtree.c and related files. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-12-11[POWERPC] Use embedded libfdt in the bootwrapperDavid Gibson
This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library.

2007-12-11[POWERPC] Merge libfdt upstream sourceDavid Gibson
This incorporates a copy of dtc libfdt into the kernel source, in arch/powerpc/boot/libfdt. This only imports the upstream sources verbatim, later patches are needed to actually link it into the kernel Makefiles.

2007-12-11[POWERPC] Update xmon slb codewill schmidt
This adds a bit more detail to the xmon SLB output. When the valid bit is set, this displays the ESID and VSID values, as well as decoding the segment size -- 1T or 256M -- and displaying the LLP bits. This supresses the output for any slb entries that contain only zeros. sample output from power6 (1T segment support): 00 c000000008000000 40004f7ca3000500 1T ESID= c00000 VSID= 4f7ca3 LLP:100 01 d000000008000000 4000eb71b0000400 1T ESID= d00000 VSID= eb71b0 LLP: 0 08 0000000018000000 0000c8499f8ccc80 256M ESID= 1 VSID= c8499f8cc LLP: 0 09 00000000f8000000 0000d2c1a8e46c80 256M ESID= f VSID= d2c1a8e46 LLP: 0 10 0000000048000000 0000ca87eab1dc80 256M ESID= 4 VSID= ca87eab1d LLP: 0 43 cf00000008000000 400011b260000500 1T ESID= cf0000 VSID= 11b260 LLP:100 sample output from power5 (notice the non-valid but non-zero entries) 10 0000000008000000 00004fd0e077ac80 256M ESID= 0 VSID= 4fd0e077a LLP: 0 11 00000000f8000000 00005b085830fc80 256M ESID= f VSID= 5b085830f LLP: 0 12 0000000048000000 000052ce99fe6c80 256M ESID= 4 VSID= 52ce99fe6 LLP: 0 13 0000000018000000 000050904ed95c80 256M ESID= 1 VSID= 50904ed95 LLP: 0 14 cf00000008000000 0000d59aca40f500 256M ESID=cf0000000 VSID= d59aca40f LLP:100 15 c000000078000000 000045cb97751500 256M ESID=c00000007 VSID= 45cb97751 LLP:100 Tested on power5 and power6.

2007-12-11[POWERPC] Use SLB size from the device treeMichael Neuling
Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.

2007-12-10Revert "PCI: fix IDE legacy mode resources"Linus Torvalds
This reverts commit fd6e732186ab522c812ab19c2c5e5befb8ec8115, which helped up things on MIPS, but was wrong for everything else. As Ralf Baechle puts it: "It seems the whole MIPS resource managment is complicated enough (out of necessity) that only a few people actually grok it. Ioports being actually memory mapped on MIPS only makes the confusion worse, sigh."

2007-12-10powerpc: Fix IDE legacy vs. native fixupsBenjamin Herrenschmidt
PowerMac and CHRP/BriQ platforms have quirks to switch some IDE controllers from legacy mode to fully native mode. Those quirks however will not work properly anymore due to a change to the generic code to better handle legacy IDE resources. This fixes it by moving those quirk to "early" quirks (so they run before resources are probed for the devices) and clearing all BARs after the conversion to force a reallocation of sane values.
