This is a big patch with new files, looks like a new base code drop.
Can you please give more explanation on the patch and what 'fmlib' is?

Shouldn't use 'printf' directly, this prevents using dynamic logging and our log
APIs. Please use a registered logtype instead.

There are lots of checkpatch warning in the block comment syntax, about missing
" * " on each line.
Other base dpaa/dpaa2 base code seems have it in the block comments, if this
won't create a maintance problem, what do you think to fix the syntax on comments?

Can you please break long lines?

Can you please remove dead code?

Please fix the leading whitespace for above two enums.
