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.) Huacai Chen(14): 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). ata: Use 32bit DMA in AHCI for Loongson 3. drm/radeon: Make radeon card usable for Loongson. ALSA: 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.
