This patch is required before the upcoming new enc28j60 driver
using SPI framework patch can be applied:
- Move legacy enc28j60.c to enc28j60_lpc2292.c.
- Change Makefile and the two affected boards' definition files.
Tested with ./MAKEALL ARM7 that both boards still compile.

Consolidate some code in mtd_get_len_incl_bad(), and fix a condition
where a valid partition could be reported as truncated if it has a
good block at the end of the device (unlikely, since the BBT is usually
there).
Fix mid-block declarations in net_part_size().

The logic to 'spread' mtd partitions needs to calculate the length in
the mtd device, including bad blocks.
This patch introduces a new function, mtd_get_len_incl_bad that can
return both the length including bad blocks and whether that length
was truncated on the device. This new function will be used by the
mtdparts spread command later in this series. The definition of the
function is #ifdef'd out in configurations that do not use the new
'mtdparts spread' command.

Get rid of the several "#if 0" sections that were keeping around Linux
code that isn't relevant to U-Boot. Besides cluttering the code, these
sections make tracking upstream changes harder, rather than easier.
It's easy to discard obviously irrelevant diff hunks that patch rejects,
but it's not as easy to notice hunks that apply cleanly to the #if 0
section, but *are* relevant to U-Boot and require modification elsewhere.
Also remove suspend/resume, as this is not applicable to U-Boot. Removal
saves 232 bytes on powerpc.

A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html,
Michele De Candia posted a patch to not count bad blocks toward the
requested size to be erased. This is desireable when you're passing in
something like $filesize, but not when you're trying to erase a partition.
Thus, a .spread subcommand (named for consistency with
http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced
to make explicit the user's desire to erase for a given amount of data,
rather than to erase a specific region of the chip.
While passing $filesize to "nand erase" is useful, accidentally passing
something like $fliesize currently produces quite unpleasant results, as the
variable evaluates to nothing and U-Boot assumes that you want to erase
the entire rest of the chip/partition. To improve the safety of the
erase command, require the user to make explicit their intentions by
using a .part or .chip subcommand. This is an incompatible user interface
change, but keeping compatibility would eliminate the safety gain, and IMHO
it's worth it.
While touching nand_erase_opts(), make it accept 64-bit offsets and sizes,
fix the percentage display when erase length is rounded up, eliminate
an inconsistent warning about rounding up the erase length which only
happened when the length was less than one block (rounding up for $filesize
is normal operation), and add a diagnostic if there's an attempt to erase
beginning at a non-block boundary.

The underlying code in nand_base.c already supports non-page-aligned reads
and writes, but the block-skipping wrapper code did not.
With block skipping, an unaligned start address is not useful since you
really want to be starting at the beginning of a partition -- or at least
that's where you want to start checking for blocks to skip, but we don't
(yet) support that. So we still require the start address to be aligned.
An unaligned length, though, is useful for passing $filesize to the
read/write command, and handling it does not complicate block skipping.

The spansion_erase currently only works when the sector size is 64KB.
cmd[1] should contain the higher 8 bit of the 24 bit address of the
sector to be erased. Currently it is holding the sector index to be
erased which happens to be the same thing when the sector size is
64KB.

The actual SPI driver for i.MX31 and i.MX51 controller
use a wrong byte ordering, because it is supposed
to work only with Freescale's devices, as the Power
Controllers (PMIC). The driver is not suitable for
general purposes, because the buffers passed to spi_xfer
must be 32-bit aligned, as it is used mainly to send
integer to PMIC devices.
The patch drops any kind of limitation and makes the
driver useful with devices controlled sending commands
composed by single bytes (or by a odd number of bytes), such as
spi flash, sensor, etc.
Because the byte ordering is changed,
any current driver using this controller must be adapted, too.

The handling of the SPI_CPOL bit inside the SPI
driver was wrong. As reported by the manual,
the meaning of the SSPOL inside the
configuration register is the same as reported
by SPI specification (0 if low in idle, 1 is high
on idle). The driver inverts this logic.
Because this patch sets the logic as specified, it is required
to clear the CPOL bit in the configuration file to adapt
to the correct logic.

This patch starts a bit PPC4xx header cleanup. First patch mostly
touches PPC440 files. A later patch will touch the PPC405 files as well.
This cleanup is done by creating header files for all SoC versions and
moving the SoC specific defines into these special headers. This way the
common header ppc405.h and ppc440.h can be cleaned up finally.

Fix potential oops on rare error path.
The patch is based on commit e7b13ec9235b9fded90f826ceeb8c34548631351
(done by David Brownell <david-b@pacbell.net>) from linux-2.6.git.
Description of the issue taken from linux kernel bugzilla:
(https://bugzilla.kernel.org/show_bug.cgi?id=9594)
The potential error can be tracked down as follows:
(1) line 807: let the second conjunct on the "if" statment be false
meaning "dev->status_ep" is null. This means the "if" evaluates
to false.
follow thru the code until...
(2) line 808: usb_ep_disable(dev->status_ep) passes in a null argument,
however "usb_ep_disable" cannot handle that:
(from include/linux/usb/gadget.h)
191 static inline int
192 usb_ep_disable (struct usb_ep *ep)
193 {
194 return ep->ops->disable (ep);
