whether the ECC corrections has failed.
This makes it similar to what is in the kernel NAND driver.

All currently available 4xx derivats have the I2C bootstrap EEPROM
located on I2C bus number 0. This patch now first sets this bus number,
so that the chip_config command also works for board with multiple

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

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
most of the time) directly from their linker scripts. This patch clean

is in preparation for the upcoming PPC4xx linker script consolidation.

This patch extends the mkconfig script to automatically create a define

the common linker script.

This patch adds support for the board IPEK01 based on the MPC5200.
The Futjitsu Lime graphics controller is configured in 16 bpp mode.
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

compatibility.

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
CONFIG_CMDLINE_EDITING was enabled.
Note that no board currently triggers this bug. Enabling
CONFIG_CMDLINE_EDITING on some boards (eg bab7xx) would result in
the bug appearing. This change is only intended to prevent someone

To make QE UART usable by Linux we should setup pin multiplexing
and turn UCC2 Ethernet node into UCC2 QE UART node.
Also, QE UART is mutually exclusive with UART0, so we can't enable
it if eSDHC is in 4-bits mode on pilot boards, or if it's a prototype
board with eSDHC in 1- or 4-bits mode.

eSDHC is mutually exlusive with UART0 (in 4-bits mode) and I2C2
(in 1-bit mode). When eSDHC is used, we should switch u-boot console to
UART1, and make the proper device-tree fixups.
Because of an erratum in prototype boards it is impossible to use eSDHC
without disabling UART0 (which makes it quite easy to 'brick' the board
by simply issung 'setenv hwconfig esdhc', and not able to interact with
U-Boot anylonger).
So, but default we assume that the board is a prototype, which is a most
safe assumption. There is no way to determine board revision from a
register, so we use hwconfig.
