warp7 can run different kernel versions, such as NXP 4.1 or mainline.
Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the eMMC
changes depending on the kernel version.
In order to avoid such issue, use UUID method to specify the rootfs
location.
Succesfully tested booting a NXP 4.1 and also a mainline kernel.

Adjust DDR3 initialization done in SPL by comparing them against

When running a NXP 4.1 kernel with U-Boot mainline on a mx6ul-evk,
we observe a hang when going into the lowest operational point of cpufreq.
This hang issue does not happen on the NXP U-Boot version.
After comparing the SPL DDR initialization against the DCD table
from NXP U-Boot, the key difference that causes the hang is the
MDREF register setting:
DATA 4 0x021B0020 0x00000800
,which means:
REF_SEL = 0 --> Periodic refresh cycle: 64kHz
REFR = 1 ---> Refresh Rate - 2 refreshes
So adjust the MDREF initialization for mx6ul_evk accordingly
to fix the kernel hang issue at low bus frequency.

Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.
Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

Since commit a13d3757f7 ("warp: Use imx_ddr_size() for calculating the
DDR size") warp board no longer boots.
The reason for the breakage is that the warp board is using the DDR
configuration from mx6slevk. A fundamental difference between warp and
mx6slevk is that warp only uses one DDR chip select while mx6slevk uses two.
The imx_ddr() function calculates the RAM size in runtime by reading the
values of registers MDCTL and MDMISC.
So in order to fix this warp boot issue, create a imximage DDR file specific
to warp, where the MDCTL register is configured to only activates a single
chip select.

This commit moved the SPL stack into SRAM C, which worked when the SPL
set the AHB1 clock down to 100 MHz to cope with the flaky SRAM C access
from the CPU.
However booting with boot0 (and thus not using SPL at all) we still run
with a 200 MHz AHB1, so any access to SRAM C is prone to fail.
Since this commit does _not_ only affect the SPL code, but also the
U-Boot proper, we fail when booting with boot0.
As the introduction of tiny-printf reduced the size of the SPL, we
can afford to have the SPL stack in SRAM A1.
This reverts commit 1a83fb4a17
and fixes booting the Pine64 when using boot0.

The board ID EEPROM and board ID stickers on p2771-0000 will use a numeric
versioning scheme, with version numbers such as 000/100/200/300/400/500.
Within NVIDIA, these versions are also known as A00/A01/A02/A03/A04/B00.
However, that numbering scheme is not easily visible outside of NVIDIA,
and so does not make much sense to use. Convert U-Boot to use the readily
visible numeric scheme.
Also, it turns out that the current A02 DT actually applies to board
versions 000/100/200 (A00..A02). Consequently rename this to 000 not 200

The revision of the original support card (rev 3.5, rev 3.6) fits in
the 8 bit width revision register. When it was extended in a weird
way, it was versioned in the format of "3.6.x" (where it should have
been "3.7", of course). What is worse, only the sub-level version
"6.x" was recorded in the 8 bit width register, completely ignoring
the compatibility of the revision register format.
This patch saves madly-versioned support cards by assuming the major
version "3" when the MSB 4 bit of the register is read as "6". With
this, the support card revision that were displayed as "6.10" is now
corrected to "3.6.10".
