ARM: 6031/1: fix Thumb-2 decompressor

2010-04-26T14:47:52+00:00

commit d4d9959c099751158c5cf14813fe378e206339c6 upstream.

98e12b5a6e05413 ("ARM: Fix decompressor's kernel size estimation for
ROM=y") broke the Thumb-2 decompressor because it added an entry in the
LC0 table but didn't adjust the offset the Thumb-2 code uses to load the
SP from that table.  Fix it.

ARM: Fix decompressor's kernel size estimation for ROM=y

2010-04-01T23:01:09+00:00

commit 98e12b5a6e05413420a7e3b3eca7fbfc2ff41b6d upstream.

Commit 2552fc2 changed the way the decompressor decides if it is safe
to decompress the kernel directly to its final location.  Unfortunately,
it took the top of the compressed data as being the stack pointer,
which it is for ROM=n cases.  However, for ROM=y, the stack pointer
is not relevant, and results in the wrong answer.

Fix this by explicitly storing the end of the biggybacked data in the
decompressor, and use that to calculate the compressed image size.

ARM: 5884/1: arm: Fix DCC console for v7

2010-01-19T20:23:16+00:00

Without this patch arch/arm/compressed/head.S defaults to generic
DCC code that does not work for v7.

For more information on the v7 DCC, see Cortex-A8 TRM
"12.11.1 Debug communications channel".

To use it with post 2.6.33-rc1 or later, you need to have:

CONFIG_DEBUG_LL=y
ONFIG_DEBUG_ICEDCC=y
CONFIG_EARLY_PRINTK=y

Earlier kernels need commit 93fd03a8c6728b58879f8af20ffd55d9c32a778b
backported.

Tested on omap3430.

ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)

2010-01-18T12:44:51+00:00

Because of the include of the decompress_inflate.c file from
boot/compress/misc.c, there are different flush() defines:

In file included from arch/arm/boot/compressed/misc.c:249:
arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0

Fix this by removing the define of flush() in misc.c for
CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
and that is being included unconditionally.

Also use a static inline function instead of define
for mach-mxc and mach-gemini to avoid similar bug
for those platforms.

arm: add support for LZO-compressed kernels

2010-01-11T17:34:05+00:00

- changes to ach/arch/boot/Makefile to make it easier to add new
   compression types
 - new piggy.lzo.S necessary for lzo compression
 - changes in arch/arm/boot/compressed/misc.c to allow the use of lzo or
   gzip, depending on the config
 - Kconfig support

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.
