Makes app image booting more reliable (256-bit rather than 8-bit verification.) Some measurements, time to boot a 655KB app.bin file and run to app_main() execution. (All for rev 1 silicon, ie no 340ms spurious WDT delay.) 80MHz QIO mode: before = 300ms after = 140ms 40MHz DIO mode: before = 712ms after = 577ms 40MHz DIO mode, secure boot enabled before = 1380ms after = 934ms (Secure boot involves two ECC signature verifications (partition table, app) that take approx 300ms each with 80MHz CPU.)
