The current GPL only licensing on the device trees makes it very
impractical for other software components licensed under another
license.
To make it easier to reuse them, the device trees for UniPhier
SoCs and boards have already been dual-licensed in Linux.
Follow this trend in U-boot too.

This makes code diff much easier.
Device trees describe hardware attributes, which are independent
of software architecture. It generally makes sense to synchronize
them beyond software projects.

[1] Align cache management functions to those in Linux kernel. I.e.:
a) Use the same functions for all cache ops (D$ Inv/Flush)
b) Split cache ops in 3 sub-functions: "before", "lineloop" and
"after". That way we may re-use "before" and "after" functions for
region and full cache ops.
[2] Implement full-functional L2 (SLC) management. Before SLC was
simply disabled early on boot. It's also possible to enable or disable
L2 cache from config utility.
[3] Disable/enable corresponding caches early on boot. So if U-Boot is
configured to use caches they will be used at all times (this is useful
in partucular for speed-up of relocation).

With new SMP-enabled CPUs with ARC HS38 cores and corresponding support
in Linux kernel it's required to add basic SMP support in U-Boot.
Currently we assume the one and only core starts execution after
power-on. So most of things in U-Boot is handled in UP mode.
But when U-Boot is used for loading and starting Linux kernel right
before jumping to kernel's entry point U-Boot:
[1] Sets all slave cores to jump to the same address [kernel's entry
point]
[2] Really starts all slav cores
In ARC's implemetation of SMP in Linux kernel all cores are supposed to
run the same start-up code. But only core with ID 0 (master core)
processes further while others are looping waiting for master core to
complete some initialization.
That means it's safe to un-pause slave cores and let them execute kernel
- they will wait for master anyway.
