powerpc/64: Remove maple platform

2024-10-29T12:01:52Z

The maple platform was added in 2004 [1], to support the "Maple" 970FX evaluation board. It was later used for IBM JS20/JS21 machines, as well as the Bimini machine, aka "Yellow Dog Powerstation". Sadly all those machines have passed into memory, and there's been no evidence for years that anyone is still using any of them. Remove the platform and related code. It can always be reinstated if there's interest. Note that this has no impact on support for 970FX based Power Macs.

xz: remove XZ_EXTERN and extern from functions

2024-09-02T03:43:27Z

XZ_EXTERN was used to make internal functions static in the preboot code. However, in other decompressors this hasn't been done. On x86-64, this makes no difference to the kernel image size. Omit XZ_EXTERN and let some of the internal functions be extern in the preboot code. Omitting XZ_EXTERN from include/linux/xz.h fixes warnings in "make htmldocs" and makes the intradocument links to xz_dec functions work in Documentation/staging/xz.rst. The alternative would have been to add "XZ_EXTERN" to c_id_attributes in Documentation/conf.py but omitting XZ_EXTERN seemed cleaner.

kbuild: use $(src) instead of $(srctree)/$(src) for source directory

2024-05-09T19:34:52Z

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for checked-in source files. It is merely a convention without any functional difference. In fact, $(obj) and $(src) are exactly the same, as defined in scripts/Makefile.build: src := $(obj) When the kernel is built in a separate output directory, $(src) does not accurately reflect the source directory location. While Kbuild resolves this discrepancy by specifying VPATH=$(srctree) to search for source files, it does not cover all cases. For example, when adding a header search path for local headers, -I$(srctree)/$(src) is typically passed to the compiler. This introduces inconsistency between upstream and downstream Makefiles because $(src) is used instead of $(srctree)/$(src) for the latter. To address this inconsistency, this commit changes the semantics of $(src) so that it always points to the directory in the source tree. Going forward, the variables used in Makefiles will have the following meanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source tree Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced with $(src).

powerpc: dts: p1010rdb: fix INTx interrupt issue on P1010RDB-PB

2024-05-07T13:20:12Z

Due to the INTA is shared with the active-low PHY2 interrupt on P1010RDB-PA board, so configure P1010RDB-PA's INTA with polarity as active-low, the P1010RDB-PB board is used separately, so configure P1010RDB-PB's INTA with polarity as active-high. The INTX in P1010RDB-PB do not work because of the pcie@0 node fixup will be overwrited by p1010si-post.dtsi file, so we move the pcie@0 node fixup to p1010rdb-pb.dts and p1010rdb-pb_36b.dts.
