Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for various reasons. We also have cases where we only build SPL in Thumb2 mode due to size constraints and wish to build the rest of the system in ARM mode. So in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to control if we build everything or just SPL (or in theory, just U-Boot) in Thumb2 mode.
