asm-generic: use asm-generic/unaligned.h for most architectures

2021-05-10T15:43:15Z

There are several architectures that just duplicate the contents of asm-generic/unaligned.h, so change those over to use the file directly, to make future modifications easier. The exceptions are: - arm32 sets HAVE_EFFICIENT_UNALIGNED_ACCESS, but wants the unaligned-struct version - ppc64le disables HAVE_EFFICIENT_UNALIGNED_ACCESS but includes the access-ok version - most m68k also uses the access-ok version without setting HAVE_EFFICIENT_UNALIGNED_ACCESS. - sh4a has a custom inline asm version - openrisc is the only one using the memmove version that generally leads to worse code.

microblaze: Add support for little-endian Microblaze

2010-10-21T05:51:59Z

Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.

microblaze: Don't use access_ok for unaligned

2009-06-02T06:39:16Z

it assumes we have an unaligned exception handler which (a) may not be true (b) costs a lot of performance Instead we'll use struct/union method for big endian accesses, and byte-shifting for little endian. Signed-off-by: John Williams
