* mips: always link byteswap helpers into decompressorArnd Bergmann2021-07-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit cddc40f5617e53f97ef019d5b29c1bd6cbb031ec ] 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.

* MIPS: boot: Fix unaligned access with CONFIG_MIPS_RAW_APPENDED_DTBPaul Cercueil2021-01-191-1/+2
| | | | | | | | | | | | | | | | | | | | | commit 4d4f9c1a17a3480f8fe523673f7232b254d724b7 upstream. The compressed payload is not necesarily 4-byte aligned, at least when compiling with Clang. In that case, the 4-byte value appended to the compressed payload that corresponds to the uncompressed kernel image size must be read using get_unaligned_le32(). This fixes Clang-built kernels not booting on MIPS (tested on a Ingenic JZ4770 board).

* MIPS: Boston: Disable EG20T prefetchPaul Burton2019-02-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 5ec17af7ead09701e23d2065e16db6ce4e137289 ] The Intel EG20T Platform Controller Hub used on the MIPS Boston development board supports prefetching memory to optimize DMA transfers. Unfortunately for unknown reasons this doesn't work well with some MIPS CPUs such as the P6600, particularly when using an I/O Coherence Unit (IOCU) to provide cache-coherent DMA. In these systems it is common for DMA data to be lost, resulting in broken access to EG20T devices such as the MMC or SATA controllers. Support for a DT property to configure the prefetching was added a while back by commit 549ce8f134bd ("misc: pch_phub: Read prefetch value from device tree if passed") but we never added the DT snippet to make use of it. Add that now in order to disable the prefetching & fix DMA on the affected systems.

* MIPS: Align kernel load address to 64KBHuacai Chen2019-01-091-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | commit bec0de4cfad21bd284dbddee016ed1767a5d2823 upstream. KEXEC needs the new kernel's load address to be aligned on a page boundary (see sanity_check_segment_list()), but on MIPS the default vmlinuz load address is only explicitly aligned to 16 bytes. Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase the alignment calculated by calc_vmlinuz_load_addr to 64KB.

* kbuild: rename LDFLAGS to KBUILD_LDFLAGSMasahiro Yamada2018-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add additional options to CC") renamed CFLAGS to KBUILD_CFLAGS. Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add additional options to AS") renamed AFLAGS to KBUILD_AFLAGS. Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS. For some reason, LDFLAGS was not renamed. Using a well-known variable like LDFLAGS may result in accidental override of the variable. Kbuild generally uses KBUILD_ prefixed variables for the internally appended options, so here is one more conversion to sanitize the naming convention.

| | | | | | | | | | | | | | | | | | | | This reverts commit 0f9da844d87796ac31b04e81ee95e155e9043132. It is true that commit 0f9da844d877 ("MIPS: boot: Define __ASSEMBLY__ for its.S build") fixed the build error, but it should not have defined __ASSEMBLY__ just for textual substitution in arbitrary data. The file is image tree source in this case, but the purpose of using CPP is to replace some macros. I merged a better solution, commit a95b37e20db9 ("kbuild: get <linux/compiler_types.h> out of <linux/kconfig.h>"). The original fix-up is no longer needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for removing some of the MIPS compiler intrinsics from arch/mips/lib, first update the build of vmlinuz to use the generic ashldi3 from lib. Both ashldi3 and bswapsi objects need to be built with different CFLAGS for inclusion to vmlinuz rather than simply including the object built for the main kernel image. The objects cannot be built directly from source, since CONFIG_MODVERSIONS changes cmd_cc_o_c to prevent this. Split the rule to ship ashldi3 and bswapsi from the relevant source locations. These files make no reference to other files in their directory, so the additional CFLAGS are apparently unnecessary - remove them as well.

|/ | | | | | | | | | | | | | | | | | | | | | The debug definitions were missing for MACH_JZ4770, resulting in a build failure when DEBUG_ZBOOT was set. Since the UART addresses are the same across all Ingenic SoCs, we just use a #ifdef CONFIG_MACH_INGENIC instead of checking for individual Ingenic SoCs. Additionally, I added a #define for the UART0 address in-code and dropped the <asm/mach-jz4740/base.h> include, for the reason that this include file is slowly being phased out as the whole platform is being moved to devicetree.
