RE: [PATCH] pm8001: support HDA (flashless) mode

["Jack Wang" <jack_wang@xxxxxxxxx>]

Thanks Mark,

So how we get the bin images? PMCS only offer the converted c Header file
for this, we need users who want to use this function convert the header
file to bin file.

Patch need a little more time to look into, will comment back soon.

Jack
