Host Booting

Host booting is performed in either an 8-bit or 16-bit scenario. By
default, little-endian format is used. If configured in Host boot mode, the
DSP does not support the boot process actively. It is the host's responsi-
bility to initialize the DSP memories properly. The DSP passively waits
until the host writes a "
