The u-boot-imx23.bd and u-boot-imx28.bd need to be preprocessed, otherwise
they have issues with out-of-tree build where elftosb tool couldn't sometimes
find the u-boot.bin and spl/u-boot-spl.bin .
Preprocess these .bd files with sed and insert full path to u-boot.bin and
spl/u-boot-spl.bin to prevent this issue. Moreover, to avoid adding more
churn into main Makefile, move all this preprocessing and u-boot.sb generation
into CPU directory instead.

The VDDMEM ramped up in very weird way as it was horribly misconfigured.
Instead of setting up VDDMEM in one swipe, let it rise slowly the same
way as VDDD and VDDA in spl_power_init.c and then only clear ILIMIT before
memory gets inited. This makes sure the VDDMEM rises sanely, not jumps up
and down as it did till now.
The VDDMEM prior to this change did this:
2V0____ .--------2V5
| `--'
0V____|
The VDDMEM now does this:
2V0_____,-----------2V5
/
0V__|
Moreover, VDDIO on MX23 uses 25mV steps while MX28 uses 50mV steps,
fix this difference too.

Untill now we power-cycle (aka: disable power on a port
and re-enabling again) one port at a time.
Delay of 20ms for Port-power to change multiplies with
number of ports in this case.
So better we parallelize this process:
disable power on all ports, wait for port-power to stabilize
and then re-enable the power subsequently.

Patch b6d7852c increases timeout for enumeration, taking
worst case to be 10 sec.
get_timer() api returns timestamp in milliseconds, which is
what we are checking in the do-while() loop in usb_hub_configure()
(get_timer(start) < CONFIG_SYS_HZ * 10).
This should give us a required check for 10 seconds, and thereby
we don't need to add additional mdelay of 100 microseconds in
each cycle.

This patch adds a new 'usb test' command, that will set a port to a USB

on both downstream hub ports and ordinary device's upstream ports. In
addition, it supports EHCI root hub ports.

This patch adds a driver for the diskonchip G4 nand flash device. It is based
on the driver from the linux kernel.
This also includes a separate SPL driver. A separate SPL driver is used because
the device operates in a different mode (reliable mode) when loading a boot
image, and also because the storage format of the boot image is different from
normal data (pages are stored redundantly). The SPL driver basically mimics how
a typical IPL reads data from the device. The special operating mode and
storage format are used to compensate for the fact that the IPL does not contain
the BCH ecc decoding algorithm (due to size constraints). Although the u-boot
SPL *could* use ecc, it operates like an IPL for the sake of simplicity and
uniformity, since the IPL and SPL share the task of loading the u-boot image.
As a side benefit, the SPL driver is very small.

If CONFIG_USB_DEV_PULLUP_GPIO is defined, a link error occurs because the
set_GPIO_mode() helper function is not implemented. This function doesn't do
much except make the code a little more readable, so I just manually coded its
equivalent and removed the prototype from the header file. It is invoked no
where else in the code.
While I was at it, I noticed that two other function prototypes in the same
header file are also neither implemented nor invoked anywhere, so I removed them
as well.

This patch adds the bitrev library from the linux kernel. This is a simple
algorithm that uses an 8 bit look-up table to reverse the bits in data types of
8, 16, or 32 bit widths. The docg4 nand flash driver uses it.
