This patch fixes a problem only seen very occasionally on Canyonlands.
The NOR flash interface (CFI driver) doesn't work reliably in all cases.
Erasing and/or programming sometimes doesn't work. Sometimes with
an error message, like "flash not erased" when trying to program an
area that should have just been erased. And sometimes without any error
messages. As mentioned above, this problem was only seen rarely and with
some PLL configuration (CPU speed, EBC speed).
Now I spotted this problem a few times, when running my Canyonlands with
the following setup (chip_config):
1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100
Changing the EBC configuration to not release the bus into high
impedance state inbetween the transfers (ATC, DTC and CTC bits set to 1
in EBC0_CFG) seems to fix this problem. I haven't seen any failure
anymore with this patch applied.

This patch introduces a weak default function for is_pci_host(),
returning 1. This is the default behaviour, since most boards only
implement PCI host functionality. This weak default can be overridden
by a board specific version if needed.

This patch consolidates the PPC4xx board specific PCIe configuration
code. This way the duplicated code is removed. Boards can implement a
special, non standard behaviour (e.g. number of PCIe slots, etc) by
overriding the weak default functions.

The asm-arm/unaligned.h includes linux/unaligned/access_ok.h
This file is unsafe to be used on ARM, since it does an unaligned memory
accesses which fails on ARM.
Lookin at Linux the basic difference seems to be the header
"include/asm-arm/unaligned.h". The Linux version of "unaligned.h"
does *not* include "access_ok.h" at all. It includes "le_byteshift.h"
and "be_byteshift.h" instead.

commit 70ed869e broke fsl pcie end-point initialization.
Returning 0 is not correct. The function must return the first free

fsl_pci_init() must still be called and a bus allocated even if the
controller is an end-point.

Some 4xx Makefiles didn't add $(SOBJ) to their board library. This was
no till now problem, since those boards included this object (init.o

is in preparation for the upcoming PPC4xx linker script consolidation.

This patch extends the mkconfig script to automatically create a define

This patch adds support for the board IPEK01 based on the MPC5200.

Signed-off-by: Wolfgang Grandegger <wg@denx.de>
In 16 bpp mode, the new IPEK01 board only requires swapping of D16 words
for D32 accesses due to the diffferent connecting to the GDC bus. This
patch introduces the configuration option VIDEO_FB_16BPP_WORD_SWAP,
which should be set for all board using the mb862xx in 16 bpp mode. For
the IPEK01, VIDEO_FB_16BPP_PIXEL_SWAP should not be set.

The new IPEK01 board can use the 32 bpp mode for the Lime graphics

To avoid board-specific code accessing the mb862xx registers directly,
the public function mb862xx_probe() has been introduced. Furthermore,
the "Change of Clock Frequency" and "Set Memory I/F Mode" registers
are now defined by CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx__MMR,
respectively. The BSPs for the socrates and lwmon5 boards have been
adapted accordingly.

Currently the CFI driver issues both AMD and Intel reset commands.
This is because the driver doesn't know yet which chips are connected.
This dual reset seems to cause problems with the M29W128G chips as
reported by Richard Retanubun. This patch now introduces a weak default
function for the CFI reset command, still with both resets. This can
be overridden by a board specific version if necessary.

The editenv command can be used to edit an environment variable.
Editing an environment variable is useful when one wants to tweak an
existing variable, for example fix a typo or change the baudrate in the
'bootargs' environment variable.

Previously setenv() would only delete an environment variable if it
was passed a NULL string pointer as a value. It should also delete an
environment variable when it encounters a valid string pointer of
0-length.
This change/fix is generally useful and is necessary for the upcoming
"editenv" command.

If the 'buf' parameter is a non-0-length string, its contents will be
edited. Previously, the initial contents of 'buf' were ignored and the
user entered its contents from scratch.
This change is necessary to support the upcoming "editenv" command but
could also be used for future commands which require a user to modify
an existing string.

Previously, passing readline() or readline_into_buffer() a NULL 'prompt'
parameter would result in puts() printing garbage when

Note that no board currently triggers this bug. Enabling
