+Subject: [PATCH 01/93] armv8: Support loading 32-bit OS in AArch32 execution
+ state
+
+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.

+Subject: [PATCH 02/93] armv8: SMP support for loading 32-bit OS
+
+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.
