MIPS: Fix gigaton of warning building with microMIPS.

2014-03-31T16:17:12+00:00

With binutils 2.24 the attempt to switch with microMIPS mode to MIPS III
mode through .set mips3 results in *lots* of warnings like

{standard input}: Assembler messages:
{standard input}:397: Warning: the 64-bit MIPS architecture does not support the `smartmips' extension

during a kernel build.  Fixed by using .set arch=r4000 instead.

This breaks support for building the kernel with binutils 2.13 which
was supported for 32 bit kernels only anyway and 2.14 which was a bad
vintage for MIPS anyway.

MIPS: Alchemy: pata_platform for DB1200

2014-03-26T22:09:21+00:00

The au1xxx-ide driver isn't any faster than pata_platform since it
spends a lot of time busy waiting for DMA to finish; faster PIO/DMA
modes only work on the db1200 with a certain cpu speed, UDMA is broken,
and finally the old IDE layer is on death row, so time to switch to
the newer ATA layer.

MIPS: Alchemy: Unify Devboard support.

2014-03-26T22:09:21+00:00

This patch merges support for all DB1xxx and PB1xxx
boards into a single image, along with a new single defconfig
for them.

Run-tested on DB1300 and DB1500.

MIPS: Alchemy: Determine cohereny at runtime based on cpu type

2014-03-26T22:09:21+00:00

All Alchemy chips have coherent DMA, but for example the USB or AC97
peripherals on the Au1000/1500/1100 are not.
This patch uses DMA_MAYBE_COHERENT on Alchemy and sets coherentio based
on CPU type.

MIPS: Alchemy: Fix unchecked kstrtoul return value

2014-03-06T19:52:28+00:00

enabled __must_check logic triggers a build error for mtx1 and gpr
in the prom init code.  Fix by checking the kstrtoul() return value.

MIPS: Alchemy: Fix DB1100 GPIO registration

2014-02-04T12:18:02+00:00

With CONFIG_GPIOLIB=y gpios need to be requested before they can be
modified.  Request the SD carddetect pins, and drop the SPI direction
setup, as the driver does that for us anyway.  This gets rid of a
lot of WARN_ON()s triggered by GPIO core, and restores functionality
of the touschreen controller.

mips: delete non-required instances of include

2014-01-24T21:39:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

MIPS: Panic messages should not end in \n.

2013-10-29T20:24:19+00:00

Panic() is going to add a \n itself and it's annoying if a panic message rolls
of the screen on a device with no scrollback.
