sh: missing symbol fix for sh4-202

2007-08-22T04:32:07+00:00

This patch adds a plat_irq_setup() symbol for sh4-202. Without
this fix it is impossible to build a working kernel using the
microdev_defconfig.

sh: Fix DSP opcode regression for SH3-DSP parts.

2007-08-21T07:56:56+00:00

Older versions of binutils do not support -Wa,-isa= tuning, which is
something we rely on for enabling DSP opcode support on the newer
parts. SH3-DSP parts can still be handled with -Wa,-dsp even if the
newer parts require the newer versions of binutils for supporting the
new opcodes.

This was broken in -rc1 when the SH4AL-DSP support was being reworked,
and is needed to get SH3-DSP working with older toolchains again.

sh: remove extraneous ; on scif_sercon_putc wait loop

2007-08-16T16:25:34+00:00

It seems we have gained an extraneous trailing ';' on one of the
wait loops in scif_sercon_putc().  Although this is completely
benign as the apparent payload is also the empty statement, it
invites error in the future.  Clean it up now.

sh: panic on machvec section misalignment.

2007-08-07T10:13:23+00:00

Now that __initmv references the machvec section unconditionally
there have been cases where folks have been mistakenly flagging
non-machvec structures with the machvec section attribute (presumably
to shut up modpost). This leads to obscure breakage in earlyprintk
amongst other places and is rather non-obvious.

Add a simple sanity check to try and catch __initmv misuse and
panic early.

sh: Fix PTRACE_PEEKTEXT/PEEKDATA fallout from generic_ptrace_peekdata().

2007-08-04T04:39:21+00:00

When generic_ptrace_peekdata() was merged, the break for these cases
ended up getting dropped, which lead to each PEEKTEXT/PEEKDATA op leaking
in to PEEKUSR and get_user_pages() always -EFAULTing. Add the break back
in.

sh: fix defconfigs for sh7751r boards

2007-08-03T01:17:47+00:00

This patch fixes up the defconfig for various sh7751r based boards
by updating them to the single cpu subtype CONFIG_CPU_SUBTYPE_SH7751R.
The following sh4 boards are updated: hs7751rvoip, landisk, lboxre2,
systemh, titan.

The current defconfigs with two subtypes defined trigger a configuration
bug which result in kernel configurations with missing board support
code. We end up with kernels without board code and with generic machvec
only.

So we need this patch to make sure the board code gets compiled in.

sh: fix cf support on r2d boards

2007-08-03T01:16:29+00:00

This patch makes sure cf support is enabled on R2D-PLUS but disabled
on R2D-1. Without this fix R2D-1 boards hang on bootup.

sh: Fix SH-X3 FPU exception handling.

2007-08-01T07:55:07+00:00

SH-X3 has the FPU exceptions on different vectors completely,
patch in do_fpu_state_restore() to the proper vectors.

Results in a much happier userspace.
