6582d7b737 sh: add spi header and r2d platform data V3
This patch adds the header file asm/spi.h and board specific code for the
r2d board. The header file contains a structure that should be used to
point out a single spi bus. The board specific code for r2d is updated with
such a structure for the new spi_sh_sci driver. The structure contains a
chip select callback plus information about the R9701 rtc chip which is
attached to the spi bus.

da2d7f4bc5 sh: update r7780rp interrupt code
This patch updates the board specific irq code for r7780rp. The new code is
very similar to the other highlander implementations, with the exception that
the r7780rp handles pci interrupts using IRL. To simplify the pci code and
use the same interrupt numbers as r7780mp and r7785rp we hook in to the
cpu specific pci vectors.

The pci interrupts and the push switch all work well with and without this
patch. CF and AX88796 are not ok though and the source of the problem is
unknown at this point. The AX88796 does for not detect it's proper mac
address (IPL gets it right) and the kernel hangs on CF access. As a workaround
this patch removes the CF and the AX88796 from the platform datain case of
r7780rp.

d4dca67bc2 sh: remove consistent alloc stuff from the machine vector
Now with the voyagergx cruft gone and the dreamcast using declared
coherent memory for pci there are no users of the consistent alloc and
free functions pointers in the machine vector.

So this little patch simply removes these function pointers from the macvec.

f93e97eaea sh: declared coherent memory support V2
This patch adds declared coherent memory support to the sh architecture. All
functions are based on the x86 implementation. Header files are adjusted to
use the new functions instead of the former consistent_alloc() code.

This version includes the few changes what were included in the fix patch
together with modifications based on feedback from Paul.

7f3edee81f sh: intc - remove default interrupt priority tables
This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.

The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

7bff489a14 sh: Always use CONFIG_HZ for HZ.
Currently the wdt forces HZ=1000 and sidesteps CONFIG_HZ completely. This
is a remnant from when HZ was hardcoded and before CONFIG_HZ was
introduced. Additionally, not all of the timers have this requirement
these days, so it's also an artificial limitation. Just kill it off and
use CONFIG_HZ directly.

0fb19dcb64 sh: get_user fixes and nommu consolidation.
When a get_user(to, from++) is called the pointer increment is performed
after its first usage, in the specific after the __add_ok invokation.
This causes a wrong get_user return value, putting a wrong character
in the destination variable. This patch solves the problem using a new
temporary pointer.

Additionally this reworks the use of the register banks, allowing for
consolidation between the MMU and nommu implementations.

cbaa118ecf sh: Preparation for uncached jumps through PMB.
Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

SH-4A and later use, and is only supportable on legacy cores.
