We currently depend SPL config options on specific machine types which doesn't
scale. Fortunately there's already a kconfig variable that tells us whether we
want to build SPL code at all, so just depend them on this.

This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this
define is set, RTL8211x PHYs (except for the RTL8211F) will have their
1000BASE-T master/slave autonegotiation disabled and forced to master
mode.
This is helpful for PHYs like the RTL8211C which produce unstable links
in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB
and A20-OLinuXino-Lime2.
There is no proper way to identify affected PHYs in software as the
RTL8211C shares its UID with the RTL8211B. Thus, this fix requires
the introduction of an #ifdef.

This commit solves CAAM coherency issue on ls2080. When caches are
enabled and CAAM's DMA's AXI transcations are not made cacheable,
Core reads/writes data from/to caches and CAAM does from main memory.
This forces data flushes to synchronize various data structures. But
even if any data in proximity of these structures is read by core,
these structures again are fetched in caches.
To avoid this problem, either all the data that CAAM accesses can be
made cache line aligned or CAAM transcations can be made cacheable.
So, this commit makes CAAM transcations as write back with write and
read allocate.

During secure boot, Linux image along with other images are validated
using bootscript. This bootscript also needs to be validated before
it executes. This requires a header for bootscript.
When secure boot is enabled, default bootcmd is changed to first
validate bootscript using the header and then execute the script.
For ls2080, NOR memory map is different from other ARM SoCs. So a new
address on NOR is used for this bootscript header (0x583920000). The
Bootscript address is mentioned in this header along with addresses of
