Subject[PATCH V5 00/16] MIPS: Add Loongson-3 based machines support.
Date
This patchset is for git repository git://git.linux-mips.org/pub/scm/
ralf/linux. Loongson-3 is a multi-core MIPS family CPU, it is MIPS64R2
compatible and has the same IMP field (0x6300) as Loongson-2. These
patches make Linux kernel support Loongson-3 CPU and Loongson-3 based
computers (including Laptop, Mini-ITX, All-In-One PC, etc.)

V1 -> V2:
1, Split the first patch to two patches, one is constant definition and
the other is CPU probing, cache initializing, etc.
2, Remove Kconfig options in the first 9 patches and put all of them in
the 10th patch.
3, Use "make savedefconfig" to generate the new default config file.
4, Rework serial port support to use PORT and PORT_M macros.
5, Fix some compile warnings.

V2 -> V3:
1, Improve cache flushing code (use cpu_has_coherent_cache macro and
remove #ifdef clauses).
2, Improve platform-specific code to correctly set driver's dma_mask/
coherent_dma_mask so no longer need workarounds for each driver (
SATA, graphics card, sound card, etc.)
3, Use PCI quirk to provide vgabios and loongson3_read_bios() go away.
4, Improve CPU hotplug code and split the poweroff failure related code
to another patch (this issue affect all MIPS CPU, not only Loongson).
5, Some other small fixes.

V3 -> V4:
1, Include swiotlb.h in radeon_ttm.c if SWIOTLB configured.
2, Remove "Reviewed-by" in patches which are added by mistake.
3, Sync the code to upstream.

V4 -> V5:
1, Split the drm patch to three patches.
2, Use platform-specific pincfgs to replace old alsa quirks.

Huacai Chen(18):
MIPS: Loongson: Add basic Loongson-3 definition.
MIPS: Loongson: Add basic Loongson-3 CPU support.

drm: Define SAREA_MAX for Loongson (PageSize = 16KB).
ALSA: HDA: Make hda sound card usable for Loongson.
MIPS: Loongson 3: Add Loongson-3 SMP support.
MIPS: Loongson 3: Add CPU hotplug support.
MIPS: Fix poweroff failure when HOTPLUG_CPU configured.
MIPS: Loongson: Add a Loongson-3 default config file.
