mx6slevk 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 SD
card changes depending on the kernel version.

In order to avoid such issue, use the UUID method to specify the
rootfs location.

We have at least a minor count of boards, that failed to re-initialize
PCI express in the Linux kernel. Typical failure rate is 20% on affected
boards. This is mitigated by commit 6ecbe137 ("drivers: pci: imx:
add imx_pcie_remove function").

However, at least on some i.MX6 custom boards, when calling
assert_core_reset() as part of the first-time PCIe init, read access
to PCIE_PL_PFLR simply hangs. Surround this readl() with
imx_pcie_fix_dabt_handler() does not help. For this reason, the forced
LTSSM detection is only used on the second assert_core_reset() that is
called shorly before starting the Linux kernel.

Latest wandboard hardware revision is revd1, which brings the following
new features:

- PFUZE100 PMIC
- AR8035 Ethernet PHY
- Upgrade Wifi/BT chip to BCM4339/BCM43430.

The detection mechanism is to probe the PMIC and when it is
found, then the revision of the board is revd1.

As the detection is done via PMIC, we need to print the board version
at a later stage via CONFIG_DISPLAY_BOARDINFO_LATE and also need
to disable CONFIG_DISPLAY_BOARDINFO, which is done much earlier.

Make the necessary adjustments for the AR8035 PHY to work on revd1.

Based on Richard Hu's work from Technexion's U-Boot tree.

Having this as a 'default y' is rather annoying because it doesn't

../cmd/bootm.c:330:7: error: 'CONFIG_SYS_MAX_FLASH_BANKS' undeclared (first use in this function); did you mean 'CONFIG_SYS_MAX_FLASH_SECT'?
   i < CONFIG_SYS_MAX_FLASH_BANKS; ++i, ++info) {

Make it 'default n' so people who develop new boards that start from a
blank defconfig have one less compilation failure to debug.
