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. Huacai Chen(16): MIPS: Loongson: Add basic Loongson-3 definition. MIPS: Loongson: Add basic Loongson-3 CPU support. MIPS: Loongson 3: Add Lemote-3A machtypes definition. MIPS: Loongson: Make Loongson-3 to use BCD format for RTC. MIPS: Loongson: Add UEFI-like firmware interface support. MIPS: Loongson 3: Add HT-linked PCI support. MIPS: Loongson 3: Add IRQ init and dispatch support. MIPS: Loongson 3: Add serial port support. MIPS: Loongson: Add swiotlb to support big memory (>4GB). MIPS: Loongson: Add Loongson-3 Kconfig options. ata: Use 32bit DMA in AHCI for Loongson 3. drm/radeon: Make radeon card usable for Loongson. 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: Loongson: Add a Loongson-3 default config file.
