Is there a good real world example of this particular use case? Even if there is enough space for having the U-Boot binary built in ARM mode, Thumb2 is still smaller and loads faster. And having reduced boot time is always nice. > 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. > > Signed-off-by: Tom Rini [...] -- Best regards, Siarhei Siamashka
