b1e6c4c3d4 Fix references to the documentation files
Many boot image configuration files refer to the
appropriate documentation file, but these references
contain typos in the directory and file name. Fix
them. Also fix reference to doc/README.SPL file.

f0b739f15f buildman: Allow conflicting tags to avoid spurious errors
Conflicting tags can prevent buildman from building two series which exist
one after the other in a branch. There is no reason not to allow this sort
of workflow with buildman, so ignore conflicting tags in buildman.

d642c467a0 build: Pull -DBUILD_TAG into separate ifdef
Currently the base setting for CFLAGS is split in two possibilities,
one with -DBUILD_TAG appended at the end and one without, the rest of
CFLAGS is the same in both cases. Change this so CFLAGS are always set

4e779ad2e5 gpio: Add support for microblaze xilinx GPIO
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:

e95504497e mmc: Split device init to decouple OCR-polling delay
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.

dd3ecf020e arm: mx23: Fix VDDMEM misconfiguration
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.

956b03e180 mtd: nand: add driver for diskonchip g4 nand flash
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.
