powerpc/85xx: typo in dts: "interupt" (four devices)

2013-11-22T22:57:25+00:00

These lines were inoperative for four years, which puts some doubt into
their importance, and it's possible the fixed version will regress, but
at the very least they should be removed instead.

powerpc/8xx: mfspr SPRN_TBRx in lieu of mftb/mftbu is not supported

2013-11-22T22:56:48+00:00

Commit beb2dc0a7a84be003ce54e98b95d65cc66e6e536 breaks the MPC8xx which
seems to not support using mfspr SPRN_TBRx instead of mftb/mftbu
despite what is written in the reference manual.

This patch reverts to the use of mftb/mftbu when CONFIG_8xx is
selected.

Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

2013-11-20T21:20:24+00:00

Pull slave-dmaengine changes from Vinod Koul:
 "This brings for slave dmaengine:

   - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as
     dmaengine can only transfer and not verify validaty of dma
     transfers

   - Bunch of fixes across drivers:

      - cppi41 driver fixes from Daniel

      - 8 channel freescale dma engine support and updated bindings from
        Hongbo

      - msx-dma fixes and cleanup by Markus

   - DMAengine updates from Dan:

      - Bartlomiej and Dan finalized a rework of the dma address unmap
        implementation.

      - In the course of testing 1/ a collection of enhancements to
        dmatest fell out.  Notably basic performance statistics, and
        fixed / enhanced test control through new module parameters
        'run', 'wait', 'noverify', and 'verbose'.  Thanks to Andriy and
        Linus [Walleij] for their review.

      - Testing the raid related corner cases of 1/ triggered bugs in
        the recently added 16-source operation support in the ioatdma
        driver.

      - Some minor fixes / cleanups to mv_xor and ioatdma"

powerpc/boot: Properly handle the base "of" boot wrapper

2013-11-04T23:09:11+00:00

The wrapper script needs an explicit rule for the "of" boot
wrapper (generic wrapper, similar to pseries). Before
0c9fa29149d3726e14262aeb0c8461a948cc9d56 it was hanlded
implicitly by the statement:

platformo=$object/"$platform".o

But now that epapr.o needs to be added, that doesn't work
and an explicit rule must be added.

powerpc/boot: Don't change link address for OF-based platforms

2013-10-30T05:00:17+00:00

Commit c55aef0e5bc6 ("powerpc/boot: Change the load address for the
wrapper to fit the kernel") adjusts the wrapper address unnecessarily
for platforms that use arch/powerpc/boot/of.c, since the code there
allocates space for the kernel wherever it can find it and doesn't
necessarily load the kernel at address 0.  Changing the link address
is actually harmful since it can cause the zImage to overlap with
Open Firmware and thus fail to boot.

To fix this, we set make_space to n for all of the platforms that
use of.o.

powerpc/b4860emu: Add device tree file for b4860emu

2013-10-29T02:11:19+00:00

B4860EMU is a emualtor target with minimum peripherals. It is based on
B4860QDS and trimmed down most peripherals due to either not modeled or
lack of board level connections. The main purpose of this minimum dts is
to speed up booting on emulator.
