2022-01-14kbuild: rename cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}Masahiro Yamada1-6/+6
GZIP-compressed files end with 4 byte data that represents the size of the original input. The decompressors (the self-extracting kernel) exploit it to know the vmlinux size beforehand. To mimic the GZIP's trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}. Unfortunately these macros are used everywhere despite the appended size data is only useful for the decompressors. There is no guarantee that such hand-crafted trailers are safely ignored. In fact, the kernel refuses compressed initramdfs with the garbage data. That is why usr/Makefile overrides size_append to make it no-op. To limit the use of such broken compressed files, this commit renames the existing macros as follows: cmd_bzip2 --> cmd_bzip2_with_size cmd_lzma --> cmd_lzma_with_size cmd_lzo --> cmd_lzo_with_size cmd_lz4 --> cmd_lz4_with_size cmd_xzkern --> cmd_xzkern_with_size cmd_zstd22 --> cmd_zstd22_with_size To keep the decompressors working, I updated the following Makefiles accordingly: arch/arm/boot/compressed/Makefile arch/h8300/boot/compressed/Makefile arch/mips/boot/compressed/Makefile arch/parisc/boot/compressed/Makefile arch/s390/boot/compressed/Makefile arch/sh/boot/compressed/Makefile arch/x86/boot/compressed/Makefile I reused the current macro names for the normal usecases; they produce the compressed data in the proper format. I did not touch the following: arch/arc/boot/Makefile arch/arm64/boot/Makefile arch/csky/boot/Makefile arch/mips/boot/Makefile arch/riscv/boot/Makefile arch/sh/boot/Makefile kernel/Makefile This means those Makefiles will stop appending the size data. I dropped the 'override size_append' hack from usr/Makefile. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <n.schier@avm.de>

Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures.

1. Add nodes for the two SPI controllers found in MIPS Creator CI20. 2. Reparent SPI clock source to effectively use MPLL and set its clock rate to 54MHz. NOTE: To use the SPI controllers, `pinctrl-0` property must be set in order to configure the used pins. As SPI functionality is multiplexed on multiple pin groups, this choice is left to the user. An example configuration: ``` &spi0 { pinctrl-0 = <&pins_spi0>; } pins_spi0: spi0 { function = "ssi0"; groups = "ssi0-dt-e", "ssi0-dr-e", "ssi0-clk-e", "ssi0-ce0-e", "ssi0-ce1-e"; bias-disable; }; ``` Consult the CI20 pinout description for more details.

2021-08-21MIPS: mscc: ocelot: disable all switch ports by defaultVladimir Oltean3-0/+23
The ocelot switch driver used to ignore ports which do not have a phy-handle property and not probe those, but this is not quite ok since it is valid to not have a phy-handle property if there is a fixed-link. It seems that checking for a phy-handle was a proxy for the proper check which is for the status, but that doesn't make a lot of sense, since the ocelot driver already iterates using for_each_available_child_of_node which skips the disabled ports, so I have no idea. Anyway, a widespread pattern in device trees is for a SoC dtsi to disable by default all hardware, and let board dts files enable what is used. So let's do that and enable only the ports with a phy-handle in the pcb120 and pcb123 device tree files.

2021-07-05mips: always link byteswap helpers into decompressorArnd Bergmann1-2/+2
My series to clean up the unaligned access implementation across architectures caused some mips randconfig builds to fail with: mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `decompress_kernel': decompress.c:(.text.decompress_kernel+0x54): undefined reference to `__bswapsi2' It turns out that this problem has already been fixed for the XZ decompressor but now it also shows up in (at least) LZO and LZ4. From my analysis I concluded that the compiler could always have emitted those calls, but the different implementation allowed it to make otherwise better decisions about not inlining the byteswap, which results in the link error when the out-of-line code is missing. While it could be addressed by adding it to the two decompressor implementations that are known to be affected, but as this only adds 112 bytes to the kernel, the safer choice is to always add them.

2021-06-30MIPS: CI20: Add second percpu timer for SMP.周琰杰 (Zhou Yanjie)1-10/+14
1.Add a new TCU channel as the percpu timer of core1, this is to prepare for the subsequent SMP support. The newly added channel will not adversely affect the current single-core state. 2.Adjust the position of TCU node to make it consistent with the order in jz4780.dtsi file.
