sh: fix sys_cacheflush error checking

2009-08-24T09:59:09Z

sys_cacheflush should return with EINVAL if the cache parameter is not one of ICACHE, DCACHE or BCACHE. So, we need to include 0 in the first check. It also adds the three definitions above as wrapper of the existent macros. PS: ltp cacheflush01 test now passes.

sh: Add sys_cacheflush() call for SH CPUs.

2009-08-24T09:16:56Z

Adds a system call to allow user code to flush code from the cache. You can use instructions for the data side, but the iside can only be done by a flush ROM which really only works with a direct mapped cache. The later SH4's have 2 way Iside, so this call allows a portable way to flush the cache. Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt
