* sh: hw-breakpoints: Add preliminary support for SH-4A UBC.Paul Mundt2009-12-081-1/+3
| | | | | | | | | | | | | | This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

* sh: Add sys_cacheflush() call for SH CPUs.Stuart Menefy2009-08-241-1/+1
| | | | | | | | | | | 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 <stuart.menefy@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* byteorder: make swab.h include asm/swab.h like a regular headerHarvey Harrison2009-01-141-1/+0
| | | | | | | | | Add swab.h to kbuild.asm and remove the individual entries from each arch, mark as unifdef as some arches have some kernel-only bits inside. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
