sh: rename suffix-y to suffix_y

2022-01-13T17:50:29+00:00

'export suffix-y' does not work reliably because hyphens are disallowed in shell variables. A similar issue was fixed by commit 2bfbe7881ee0 ("kbuild: Do not use hyphen in exported variable name"). If I do similar in dash, ARCH=sh fails to build. $ mv linux linux~ $ cd linux~ $ dash $ make O=foo/bar ARCH=sh CROSS_COMPILE=sh4-linux-gnu- defconfig all make[1]: Entering directory '/home/masahiro/linux~/foo/bar' [ snip ] make[4]: *** No rule to make target 'arch/sh/boot/compressed/vmlinux.bin.', needed by 'arch/sh/boot/compressed/piggy.o'. Stop. make[3]: *** [/home/masahiro/linux~/arch/sh/boot/Makefile:40: arch/sh/boot/compressed/vmlinux] Error 2 make[2]: *** [/home/masahiro/linux~/arch/sh/Makefile:194: zImage] Error 2 make[1]: *** [/home/masahiro/linux~/Makefile:350: __build_one_by_one] Error 2 make[1]: Leaving directory '/home/masahiro/linux~/foo/bar' make: *** [Makefile:219: __sub-make] Error 2 The maintainer of GNU Make stated that there is no consistent way to export variables that do not meet the shell's naming criteria. (https://savannah.gnu.org/bugs/?55719) Consequently, you cannot use hyphens in exported variables. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

sh: Add missing FORCE prerequisites in Makefile

2021-09-19T01:13:42+00:00

make: arch/sh/boot/Makefile:87: FORCE prerequisite is missing Add the missing FORCE prerequisites for all build targets identified by "make help".

sh: boot: add intermediate vmlinux.bin* to targets instead of extra-y

2021-09-17T18:00:04+00:00

You do not need to build all of vmlinux.bin* They are built on demand as prerequsites of uImage.bin*, hence should be added to targets instead of extra-y. Signed-off-by: Masahiro Yamada Tested-by: John Paul Adrian Glaubitz Signed-off-by: Rich Felker

Kbuild: centralize MKIMAGE and cmd_uimage definitions

2012-03-26T13:49:20+00:00

All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib to avoid duplication. All ARCHs have similar definitions of cmd_uimage. Place a sufficiently parameterized version in Makefile.lib to avoid duplication.

sh: kexec: Add PHYSICAL_START

2011-10-28T06:03:43+00:00

Add PHYSICAL_START kernel configuration parameter to set the address at which the kernel should be loaded. It has been observed on an sh7757lcr that simply modifying MEMORY_START does not achieve this goal for 32bit sh. This is due to MEMORY_OFFSET in arch/sh/kernel/vmlinux.lds.S bot being based on MEMORY_START on such systems. Signed-off-by: Simon Horman Signed-off-by: Paul Mundt

sh: fixed PMB mode refactoring.

2010-01-13T09:31:48+00:00

This introduces some much overdue chainsawing of the fixed PMB support. fixed PMB was introduced initially to work around the fact that dynamic PMB mode was relatively broken, though they were never intended to converge. The main areas where there are differences are whether the system is booted in 29-bit mode or 32-bit mode, and whether legacy mappings are to be preserved. Any system booting in true 32-bit mode will not care about legacy mappings, so these are roughly decoupled. Regardless of the entry point, PMB and 32BIT are directly related as far as the kernel is concerned, so we also switch back to having one select the other. With legacy mappings iterated through and applied in the initialization path it's now possible to finally merge the two implementations and permit dynamic remapping overtop of remaining entries regardless of whether boot mappings are crafted by hand or inherited from the boot loader.
