commit 1542fbdeec
introduced one new bug to chip-select interleaving.
Single DDR controller also can do the chip-select
interleaving if there is dual-rank or qual-rank DIMMs.

Sometimes, inside NetLoop, eth_halt() is called before eth_init() has
been called. This is harmless except for free() calls to pointers
which have not been allocated yet.
This patch initializes those pointers to NULL and allocates them only
the first time. This way we can get rid of free calls in halt callback.
This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.

This patch fixes erroneous access to the ethernet PHY which broke the driver.
1. Selector field in the auto-negotiation register must be 0x00001 for
using 802.3, not 0x00000 which is reseved.
2. Access to the PHY address specified by CONFIG_FEC_MXC_PHYADDR, not
0x0 fixed address.
This has been tested in i.MX27 Litekit board and eldk-4.2 toolchains.
Now using proper defines for auto-negotiation register.

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.

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"

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

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.

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.

This change has 3 goals:
- Have secondary cores be released into spin loops at their 'true'
address in SDRAM. Previously, secondary cores were put into spin
loops in the 0xfffffxxx address range which required that boot page
translation was always enabled while cores were in their spin loops.
- Allow the TLB window that the primary core uses to access the
secondary cores boot page to be placed at any address. Previously, a
TLB window at 0xfffff000 was always used to access the seconary cores'
boot page. This TLB address requirement overlapped with other
peripherals on some boards (eg XPedite5370). By default, the boot
page TLB will still use the 0xfffffxxx address range, but this can be
overridden on a board-by-board basis by defining a custom
CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page
remains in use while U-Boot executes. Previously it was only
temporarily used, then restored to its initial value.
- Allow Boot Page Translation to be disabled on bootup. Previously,
Boot Page Translation was always left enabled after secondary cores
were brought out of reset. This caused the 0xfffffxxx address range
to somewhat "magically" be translated to an address in SDRAM. Some
boards may not want this oddity in their memory map, so defining
CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after
the secondary cores are initialized.
These changes are only applicable to 85xx boards with CONFIG_MP defined.
