The jtag tstc operation was checking the hardware to see if data is
available from it (which is fine for the jtag getc operation), but the
higher layers need to know whether any data is available. Since we have
to read up to 4 bytes at a time from the hardware, the higher layers need
to know they can consume the cached bytes as well.

On the pcm030 the environment is located in the onboard EEPROM. But we want
to handle flash sector protection in a safe manner. So we must read the
unlock environment variable from EEPROM instead from flash.
This patch is required as long the evironment is saved into the EEPROM.
Stefan: Additional change as suggested by Wolfgang, use bigger char array
(instead of 4).

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.
The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board.
It is essentially the same, with a few minor differences.

On systems where U-Boot is linked to another address than it really lays
(e.g. backup image), calls via function pointers must be fixed with a
'+= gd->reloc_off'.
This was not done for none_compr in ubifs_compressors_init() what leads
to system crash on ubifsmount command.

This patchset adds these UBIFS related commands:
- ubifsmount
Mount an UBIFS volume
- ubifsls
List a directory of the mounted UBIFS volume
- ubifsload
Load a file from the mounted UBIFS volume to memory

The U-Boot UBIFS implementation is largely a direct copy from the current
Linux version (2.6.29-rc6). As already done in the UBI version we have an
"abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock()
...). This makes it possible to use the original Linux code with very
little changes. And by this we can better update to later Linux versions.
I removed some of the Linux features that are not used in the U-Boot
version (e.g. garbage-collection, write support).

This patch adds LZO decompression support to U-Boot. It is needed for
the upcoming UBIFS support, since UBIFS uses LZO as default compressor/
decompressor. Since we only support read-only in UBIFS, only the
decompressor is needed.
All this is copied with minor changes from the current Linux kernel
version (2.6.28-rc8).
This patch only implements this LZO decompressor support for PPC.
Other platforms using UBIFS will have to add the required
"include/asm/unaligned.h" as well. It should be fairly easy to copy this
from the Linux source tree as I have done it for PPC in this patch.

Currently the mtdparts commands are included in the jffs2 command support.
This doesn't make sense anymore since other commands (e.g. UBI) use this
infrastructure as well now. This patch separates the mtdparts commands from
the jffs2 commands making it possible to only select mtdparts when no JFFS2
support is needed.

Rewrite interrupt handling functionality for the i386 port. Separated
functionality into separate CPU and Architecture components.
It appears as if the i386 interrupt handler functionality was intended
to allow multiple handlers to be installed for a given interrupt.
Unfortunately, this functionality was not fully implemented and also
had the problem that irq_free_handler() does not allow the passing
of the handler function pointer and therefore could never be used to
free specific handlers that had been installed for a given IRQ.
There were also various issues with array bounds not being fully
tested.
I had two objectives in mind for the new implementation:
1) Keep the implementation as similar as possible to existing
implementations. To that end, I have used the leon2/3
implementations as the reference
2) Seperate CPU and Architecture specific elements. All specific i386
interrupt functionality is now in cpu/i386/ with the high level
API and architecture specific code in lib_i386. Functionality
specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has
been further split out into an individual file to allow for the
implementation of the PIC architecture of the SC520 CPU (supports
more IRQs)

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
In the ppc case, these things are part of the legacy ABI, so keep them
around but mark them as legacy so no new code will touch them.
Also stop calling load_sernum_ethaddr() since all boards now implement
this as a stub.
