Quite a few places use getenv() in a condition context, provoking a

Users migrating Freescale's PowerPC SoC U-Boot code to their custom
board, often overlook the need to execute set_liodns() and
setup_portals() being called by platform files.
So Move set_liodns() and setup_portals() to common u-boot boot
sequence

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

find_tlb_idx() is called in board_early_init_r() on multiple boards.
The return value is not checked before being used to disable a TLB.
In normal case the return value wouldn't be -1. In case of a mis-
configuration during porting to a new board, checking the return value
may be helpful to reveal some user errors.

A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to
increase and cause the PLL to unlock when the temperature delta from the
time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V
(or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC
VCO. Only the protocols using Ring VCOs are impacted.
Workaround:
For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need
to use alternate serdes protocols. The alternate option has the same
functionality as the original option; the only difference being LC VCO
rather than Ring VCO.

Allow VDD voltage overriding with a command. This is an add-on feasture of
VID. To override VDD, use command vdd_override with the value of voltage
in mV, for example
vdd_override <voltage in mV, eg. 1050>
The above example will set the VDD to 1.050 volt. Any wrong value out of
range of 0.8188 to 1.2125 volt or invalid string is ignored.
In addition to the command, if overriding VDD is needed earlier in booting
process, save an variable and reboot:
setenv t4240qds_vdd_mv <voltage in mV>
saveenv
