qe_setbrg() currently takes an integer to indicate the BRG number. Change that to take an enum qe_clock instead, since this enum is intended to represent clock sources. Signed-off-by:

Updated guts_set_dmacr() to enumerate the DMA controllers at 0, instead of 1, so that it now matches other related functions. Added function guts_set_pmuxcr_dma() to set the external DMA control bits in the PMUXCR register of the global utilities structure. Signed-off-by:

isel (Integer Select) is a new user space instruction in the PowerISA 2.04 spec. Not all processors implement it so lets emulate to ensure code built with isel will run everywhere. Signed-off-by: -

* Added SPRN for new architectural features added for embedded: - Alternate Time Base (ATB, ATBL, ATBU) - Doorbell Interrupts (IVOR36, IVOR37) - SPRG8/9 - External Proxy (EPR) - External PID load/store (EPLC, EPSC) * Added BUCSR for Freescale Embedded Processors * Moved around MAS7 so its in numeric order Signed-off-by: -

This makes the early debug option force the console loglevel to the max. The early debug option is meant to catch messages very early in the kernel boot process, in many cases, before the kernel has a chance to parse the "debug" command line argument. Thus it makes sense when CONFIG_PPC_EARLY_DEBUG is set, to force the console log level to the max at boot time. Signed-off-by:

This adds a variant of of_translate_address that uses the dma-ranges property instead of "ranges", it's to be used by PCI code in parsing the dma-ranges property. Signed-off-by:

This removes "volatile" from the MMIO pointer udbg_comport in udbg_16550.c driver, it's useless and makes checkpatch.pl complain when adding things to this file. Signed-off-by:

The 32 bits PCI code will display a rather scary error message PCI: Cannot allocate resource region N of device XXX at boot when the existing setup of a device as left by the firmware doesn't match the kernel needs and the device needs to be moved. This is often not an error at all, as the kernel will generally easily reallocate the device elsewhere. This changes the message to something less scary and lowers its level from error to warning.

The 32-bit powerpc resource fixup code uses unsigned longs to do the offsetting of resources which overflows on platforms such as 4xx where resources can be 64 bits. This fixes it by using resource_size_t instead. However, the IO stuff does rely on some 32 bits arithmetic, so we hack by cropping the result of the fixups for IO resources with a 32 bits mask. This isn't the prettiest but should work for now until we change the 32 bits PCI code to do IO mappings like 64 bits does, within a reserved are of the kernel address space. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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 authored
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. Signed-off-by:

David Gibson authored
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. Signed-off-by:

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.

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. Signed-off-by:
