There are different parts from one SoC. Take i.MX6ULL for example,
some part might not have ENET, some might have; some might not have
USB, some might have. The information could be got from OCOTP,
to make one image support the different parts, we need runtime
disable linux kernel dts node and uboot driver probe if the
corresponding module not exists in the part.

The i.MX6DP and i.MX6QP incorporate NoC interconnect logic
which needs to be configured in order to use external DDR memory.
This patch enables the SPL to configure the necessary registers
in accordance with the NXP engineering bulletin EB828.

The %08X format returns just zeroes with tiny printf, which is

Previously the SPL size on all iMX6 platforms was restricted to 68KB
because the OCRAM size on iMX6SL/DL parts is only 128KB. However, the
other iMX6 variants have 256KB of OCRAM. Add an option
CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
don't need to support the SL/DL variants. This allows for an SPL size of
196KB, which makes it much easier to use configurations such as SPL with
driver model and FDT control.
