Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.
Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.
There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.
Adding several gpios IP is also possible and supported.
For listing gpio configuration please use "gpio status" command
This patch also remove one compilation warning:

Most of time that MMC driver spends on initializing a device is polling
OCR (operation conditions register). To decouple this polling loop,
device init is split into two parts: The first part fires the OCR query
command, and the second part polls the result. So the caller is now no
longer bound to the OCR-polling delay; he may fire the query, go
somewhere and then come back later for the result.
To use this, call mmc_set_preinit() on any device which needs this.
This can save significant amounts of time on boot (e.g. 200ms) by
hiding the MMC init time behind other init.

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.

The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a
second USB port that can be configured in either host, peripheral (aka
device), or OTG (on-the-go) mode. When configured in host mode, if
the port is connected to another USB host, damage to the board can
occur.
To avoid this, we change the default setting to peripheral mode. Ideally,
we'd set it to OTG mode, but currently there is no OTG support for
these boards.
Setting the hwconfig variable will also update the device tree, and so
Linux will configure the port for peripheral mode as well.

currently allocated 128 bytes are just a bit too small for this
new struct.
This patch now uses the automatically generated struct size instead to

currently reserve a tight space of 128 bytes for the global_data

Downloaded from http://slre.sourceforge.net/
and adapted for U-Boot environment.
Used to implement regex operations on environment variables.
Code size is ~ 3.5 KiB on PPC.
To enable this code, define the CONFIG_REGEX option in your board
config file.
Note: There are more recent versions of the SLRE library available at
http://slre.googlecode.com ; unfortunately, the new code has a heavily
reorked API which makes it less usable for our purposes:
- the return code is strings, which are more difficult to process
- we don't get any information any more which sub-string of the data
was matched by the given regex
- it is much more cumbersome to work with arbitrary expressions, where
for example the number of substrings for capturing are not known at
compile time
Also, there does not seem to be any real changes or improvements of
the functionality.
Because of this, we deliberately stick with the older code.
Note 2: the test code (built when SLRE_TEST is defined) was modified
to allow for more extensive testing; now we can test the regexp
matching on all lines on a text file (instead of the whole data in the
file as a single block).
