ARM: 6503/1: Thumb-2: Restore sensible zImage header layout for CONFIG_THUMB2_KERNEL

2010-11-30T13:44:26Z

The code which makes up the zImage header intends to leave a 32-byte gap followed by a branch to the real entry point, a magic number, and a word containing the absolute entry point address. This gets messed up with with CONFIG_THUMB2_KERNEL, because the size of the initial padding NOPs changes. Instead, the header can be made fully compatible by restoring it to ARM. In the Thumb-2 case, we can replace the initial NOPs with a sequence which switches to Thumb and jumps to the real entry point. As a consequence, the zImage entry point is now always ARM, so no special magic is needed any more for the uImage rules in the Thumb-2 case.

ARM: 6502/1: Thumb-2: Fix CONFIG_THUMB2_KERNEL breakage in compressed/head.S

2010-11-30T13:44:25Z

Some instruction operand combinations are used here which are nor permitted in Thumb-2. In particular, most uses of pc as an operand are disallowed in Thumb-2, and deprecated in ARM from ARMv7 onwards. The modified code introduced by this patch should be compatible with all architecture versions >= v3, with or without CONFIG_THUMB2_KERNEL.

ARM: avoid marking decompressor .stack section as having contents

2010-11-22T12:00:59Z

The .stack section doesn't contain any contents, and doesn't require initialization either. Rather than marking the output section with 'NOLOAD' but still having it exist in the object files, mark it with %nobits which avoids the assembler marking the section with 'CONTENTS'.

ARM: Fix build error when using KCONFIG_CONFIG

ARM: Partially revert "Auto calculate ZRELADDR and provide option for exceptions"

2010-09-09T21:39:41Z

Partially revert e69edc7, which introduced automatic zreladdr support. The change in the way the manual definition is defined seems to be error and conflict prone. Go back to the original way we were handling this for the time being, while keeping the automatic zreladdr facility. Acked-by: Uwe Kleine-König

ARM: 6286/1: fix Thumb-2 decompressor broken by "Auto calculate ZRELADDR"

2010-08-10T21:10:51Z

"ARM: Auto calculate ZRELADDR and provide option for exceptions" broke the Thumb-2 decompressor because it removed 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, and also change the ARM code to use the separate SP-load since ARM instructions that include the SP in the LDM register list are deprecated.

[ARM] pxa: PXA_SHARPSL_DETECT_MACH_ID to include head-sharpsl.S

2010-08-05T06:32:23Z

With kexec-based kernel boot loader on Zaurus, the machine ID is actually correctly passed, and head-sharpsl.S is not necessary. Introduce PXA_SHARPSL_DETECT_MACH_ID, and include head-sharpsl.S only when that's explicitly enabled. Signed-off-by: Eric Miao
