From: Du Huanpeng <[email protected]> Loongson 1C is a cost-effective SOC chip for industrial control and the Internet of Things. The Loongson 1C includes a floating-point processing unit, supports multiple types of memory, and supports high-capacity MLC NAND Flash. Loongson 1C provides developers with a wealth of peripheral interfaces and on-chip modules, including Camera controller, USB OTG and USB HOST interfaces, AC97/I2S controller, LCD controller, SPI interface, UART interface, etc., providing sufficient computing power and multi-application connectivity. Some highlights of this SoC are: - Single core LS232, MIPS32 instruction set compatible, main frequency 300MHZ - 16KB data cache and 16KB instruction cache - 64 bit float unit, hardware division - 8/16 bit SDRAM controller, 45 ~ 133MHz - 8/16 bit SRAM, NAND - I2S/AC97, LCD, MAC, USB, OTG, SPI, I2C, PWM, CAN, SDIO, ADC - 12 UARTs Links: https://www.loongson.cn/ introduce base support for the ls1c300 SoC. - debug UART2 - serial console - clock - watchdog - sysreset - uart Signed-off-by: Du Huanpeng <[email protected]> --- MAINTAINERS | 9 ++++ arch/mips/Kconfig | 11 ++++ arch/mips/Makefile | 1 + arch/mips/mach-loongson/Kconfig | 69 ++++++++++++++++++++++++ arch/mips/mach-loongson/Makefile | 6 +++ arch/mips/mach-loongson/cpu.c | 19 +++++++ arch/mips/mach-loongson/ls1c300/Makefile | 7 +++ arch/mips/mach-loongson/ls1c300/init.c | 61 +++++++++++++++++++++ arch/mips/mach-loongson/spl.c | 46 ++++++++++++++++ 9 files changed, 229 insertions(+) create mode 100644 arch/mips/mach-loongson/Kconfig create mode 100644 arch/mips/mach-loongson/Makefile create mode 100644 arch/mips/mach-loongson/cpu.c create mode 100644 arch/mips/mach-loongson/ls1c300/Makefile create mode 100644 arch/mips/mach-loongson/ls1c300/init.c create mode 100644 arch/mips/mach-loongson/spl.c
