0x10 0x120 The nand/private/movable.sed, encrypted with AES-CTR using the above MAC for the counter.

Description

This decrypts the input SEED and verifies it with the input AES-CCM MAC, verifies the RSA-signature, then writes the data to nand/private/movable.sed. The nonce used for the AES-CCM MAC is all-zero.
