Boot9 can also boot from non-NAND. For this a different set of RSA pubks are used(separate pubks for retail/devunit like NAND). The spiflash FIRM image for this is also encrypted with AES-CTR using a normalkey stored in prot_boot9(separate for retail/devunit). This encryption is basically used instead of what is used for NAND-firm-partitions. | Boot9 can also boot from non-NAND.
