ARM: zImage: the page table memory must be considered before relocation

2011-05-07T04:07:58+00:00

For correctness, the initial page table located right before the
decompressed kernel should be considered when determining if relocation
is required.

ARM: zImage: make sure not to relocate on top of the relocation code

2011-05-07T04:07:53+00:00

If the zImage load address is slightly below the relocation address,
there is a risk for the copied data to overwrite the copy loop or
cache flush code that the relocation process requires.  Always
bump the relocation address by the size of that code to avoid this
issue.

Noticed by Tony Lindgren .

While at it, let's start the copy from the restart symbol which makes
the above code size computation possible by the assembler directly
(same sections), given that we don't need to preserve the code before
that point anyway. And therefore we don't need to carry the _start
pointer in r5 anymore.

ARM: zImage: Fix bad SP address after relocating kernel

2011-05-07T03:56:43+00:00

Otherwise cache_clean_flush can overwrite some of the relocated
area depending on where the kernel image gets loaded. This fixes
booting on n900 after commit 6d7d0ae51574943bf571d269da3243257a2d15db
(ARM: 6750/1: improvements to compressed/head.S).

Thanks to Aaro Koskinen  for debugging
the address of the relocated area that gets corrupted, and to
Nicolas Pitre  for the other uncompress
related fixes.

ARM: zImage: make sure the stack is 64-bit aligned

2011-05-07T03:55:49+00:00

With ARMv5+ and EABI, the compiler expects a 64-bit aligned stack so
instructions like STRD and LDRD can be used.  Without this, mysterious
boot failures were seen semi randomly with the LZMA decompressor.

While at it, let's align .bss as well.

ARM: 6826/1: Merge v6 and v7 DEBUG_LL DCC support

2011-03-28T18:01:43+00:00

The inline assembly differences for v6 vs. v7 are purely
optimizations. On a v7 processor, an mrc with the pc sets the
condition codes to the 28-31 bits of the register being read. It
just so happens that the TX/RX full bits the DCC support code is
testing for are high enough in the register to be put into the
condition codes. On a v6 processor, this "feature" isn't
implemented and thus we have to do the usual read, mask, test
operations to check for TX/RX full. Thus, we can drop the v7
implementation and just use the v6 implementation for both.

mmc: Add MMC_PROGRESS_*

2011-03-24T16:24:57+00:00

This is my second attempt to make this enum generally available.
The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h.
However this is not sufficiently generic as the enum will be
used by SDHI boot code.

mmc, ARM: Rename SuperH Mobile ARM zboot helpers

2011-03-24T16:24:57+00:00

These headers and helpers will also be used for SDHI boot
so the mmcif name will start to make a lot less sense.
