MIPS: Loongson64: Add UART node for LS7A PCH

2020-09-21T20:19:07Z

When I update the latest kernel on the Loongson platform used with LS7A bridge chip, the serial console has no output, this is because the machine uses LS7A UART0 instead of CPU UART0, add UART node for LS7A PCH to enhance the compatibility.

MIPS: Loongson-3: Enable COP2 usage in kernel

2020-09-21T20:15:03Z

Loongson-3's COP2 is Multi-Media coprocessor, it is disabled in kernel mode by default. However, gslq/gssq (16-bytes load/store instructions) overrides the instruction format of lwc2/swc2. If we wan't to use gslq/ gssq for optimization in kernel, we should enable COP2 usage in kernel. Please pay attention that in this patch we only enable COP2 in kernel, which means it will lose ST0_CU2 when a process go to user space (try to use COP2 in user space will trigger an exception and then grab COP2, which is similar to FPU). And as a result, we need to modify the context switching code because the new scheduled process doesn't contain ST0_CU2 in its THERAD_STATUS probably. For zboot, we disable gslq/gssq be generated by toolchain. Signed-off-by: Huacai Chen Signed-off-by: Thomas Bogendoerfer

MIPS: dts/ingenic: Cleanup qi_lb60.dts

2020-09-07T20:18:24Z

Cleanup a bit the Device Tree file: 1. Respect the number of cells in GPIO descriptors and keyboard matrix; 2. Use 'ecc-engine' instead of deprecated 'ingenic,bch-controller' property; 3. The NAND's rb-gpios is actually active high; 3. The FRE/FWE pins must be configured in the proper mode for the NAND to work if it was not already done by the bootloader.

MIPS: Add support for ZSTD-compressed kernels

2020-09-03T08:13:24Z

Add support for self-extracting kernels with a ZSTD compression. Tested on a kernel for the GCW-Zero, it allows to reduce the size of the kernel file from 4.1 MiB with gzip to 3.5 MiB with ZSTD, and boots just as fast. Compressed kernels are now also compiled with -D__DISABLE_EXPORTS in order to disable the EXPORT_SYMBOL() macros inside of lib/zstd/decompress.c.
