kbuild: use INSTALLKERNEL to select customized installkernel script

2009-09-20T10:18:14+00:00

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.

The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.

The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]

This patch undos what Ian did in commit:

  0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
  ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

The patch has been lightly tested on x86 only - but all changes
looks obvious.

sh: Remove implicit sign extension from assembler immediates

2009-08-24T08:09:53+00:00

The SH instruction set has several instructions which accept an 8 bit
immediate operand. For logical instructions this operand is zero extended,
for arithmetic instructions the operand is sign extended. After adding an
option to the assembler to check this, it was found that several pieces
of assembly code were assuming this behaviour, and in one case
getting it wrong.

So this patch explicitly sign extends any immediate operands, which makes
it obvious what is happening, and fixes the one case which got it wrong.

sh: bzip2/lzma uImage support.

2009-07-21T08:24:36+00:00

This builds on the bzip2/lzma zImage support change and wires it up for
uImages. Based on the blackfin implementation.

sh64: Don't use PHYSADDR() for output_addr calculation.

Opencode the MEMORY_START offset directly, sh64 uses a slightly different

sh: rename arch/sh/boot/compressed/misc_32.c -> misc.c

This is now used by both sh64 and regular sh, kill off the old sh64

This makes some minor changes to misc_32.c so that it can be used by
sh64.
