The default reserved memory for CMA is high memory. If LPAE is enabled,
highmem pages are non-remapped and can not be used with

To support loading a 32-bit OS, the execution state will change from
AArch64 to AArch32 when jumping to kernel.
The architecture information will be got through checking FIT image,
then U-Boot will load 32-bit OS or 64-bit OS automatically.

Spin-table method is used for secondary cores to load 32-bit OS. The
architecture information will be got through checking FIT image and
saved in the os_arch element of spin-table, then the secondary cores
will check os_arch and jump to 32-bit OS or 64-bit OS automatically.

As the issue about the stack will get corrupted when switching between
the early and final mmu tables is fixed by commit
70e21b06425ad6e1e90931333a704a600941cfff, the workaround to flush dcache
is unnecessary and will be removed.

For LS1021A Secure Boot, SPARE2 register is used and modified by the
IBR. To avoid the conflict, SPARE4 is used instead of SPARE2 to store
the entry point of kernel. This patch is to get the entry point of
kernel from SPARE4 instead of SPARE2.
