MIPS: jz4740: Rename jz4740 folders to ingenic

2020-09-18T14:35:05+00:00

Now that all the jz4740 platform code has been removed, and we're left with only a Kconfig and the cpu-feature-overrides.h file, finalize the cleanup process by renaming the jz4740 and include/mach-jz4740 folders to ingenic and include/mach-ingenic.

MIPS: jz4740: Drop all obsolete files

2020-09-18T14:34:32+00:00

Support for Ingenic SoCs is now provided by the arch/mips/generic/ code, so all files in the arch/mips/jz4740/ folder can dropped, except for the Kconfig, and the cpu-feature-overrides.h header file. Signed-off-by: Paul Cercueil Signed-off-by: Thomas Bogendoerfer

MIPS: generic: Add support for Ingenic SoCs

2020-09-18T14:33:59+00:00

Add support for Ingenic SoCs in arch/mips/generic/. The Kconfig changes are here to ensure that it is possible to compile either a generic kernel that supports Ingenic SoCs, or a Ingenic-only kernel, both using the same code base, to avoid duplicated code.

MIPS: ingenic: Hardcode mem size for qi,lb60 board

2020-07-31T15:48:57+00:00

Old Device Tree for the qi,lb60 (aka. Ben Nanonote) did not have a 'memory' node. The kernel would then read the memory controller registers to know how much RAM was available. Since every other supported board has had a 'memory' node from the beginning, we can just hardcode a RAM size of 32 MiB when running with an old Device Tree without the 'memory' node.

MIPS: ingenic: Use fw_passed_dtb even if CONFIG_BUILTIN_DTB

2020-07-31T15:48:19+00:00

The fw_passed_dtb is now properly initialized even when CONFIG_BUILTIN_DTB is used, so there's no need to handle it in any particular way here. Note that the behaviour is slightly different, as the previous code used the built-in Device Tree unconditionally, while now the built-in Device Tree is only used when the bootloader did not provide one.

MIPS: X2000: Add X2000 system type.

2020-07-24T09:13:57+00:00

1.Add "PRID_COMP_INGENIC_13" and "PRID_IMP_XBURST2" for X2000. 2.Add X2000 system type for cat /proc/cpuinfo to give out X2000. Signed-off-by: 周琰杰 (Zhou Yanjie) Signed-off-by: Thomas Bogendoerfer

MIPS: Ingenic: Add YSH & ATIL CU Neo board support.

2020-07-16T08:57:44+00:00

Add a device tree and a defconfig for the Ingenic X1830 based YSH & ATIL CU Neo board. Tested-by: 周正 (Zhou Zheng) Signed-off-by: 周琰杰 (Zhou Yanjie) Signed-off-by: Thomas Bogendoerfer

MIPS: Ingenic: Add Ingenic X1830 support.

2020-07-16T08:54:26+00:00

Support the Ingenic X1830 SoC using the code under arch/mips/jz4740. This is left unselectable in Kconfig until a X1830 based board is added in a later commit. Tested-by: 周正 (Zhou Zheng) Signed-off-by: 周琰杰 (Zhou Yanjie) Signed-off-by: Thomas Bogendoerfer

MIPS: ingenic: Add support for the RS90 board

2020-07-16T08:48:09+00:00

The RS-90, better known as RetroMini, is a small and pocketable handheld gaming console from YLMChina. It has little more than a JZ4725B SoC, a NAND, a screen, some buttons and a speaker. Signed-off-by: Paul Cercueil Signed-off-by: Thomas Bogendoerfer

MIPS: ingenic: Add support for the JZ4725B SoC

2020-07-16T08:47:50+00:00

Add preliminary support for boards based on the JZ4725B SoC from Ingenic. The JZ4725B SoC is supposed to be older than the JZ4740 SoC, but its internals are much closer to what can be found on the JZ4750 and newer SoCs. It is low-power SoC with a MIPS32r1 SoC running at ~360 MHz, and no FPU. Signed-off-by: Paul Cercueil Signed-off-by: Thomas Bogendoerfer
