When ADSP OS is loaded from adsp.elf, it loads two sections : adsp os and the vector table. The vector table is copied to a local buffer before writing to the EVP registers. There is a probability that, if the adsp.elf is hacked / modified by an attacker, it can write to other APE register spaces. Hence, the destination address obtained from the elf is checked with evp base before copying. Also, this fixes out of array-bound writing to evp buffer.
