[PATCH v2 0/7] Add PAS and MSA based Modem support

[PATCH v2 0/7] Add PAS and MSA based Modem support

[Sibi Sankar]

Add PAS based modem support on SC7180 SoCs and update the device node to
support MSA based modem boot.

V2:
 * use memory-region to reference mba/mpss regions [Bjorn]
 * move peripheral memory regions to the board dts [Bjorn]
 * overload the base remoteproc_mpss node wherever possible [Bjorn]
 * Pick up Bjorn's R-b

Patch [1,2] - Add PAS based modem support
Patch [3,4] - use memory-region to reference mba/mpss regions
Patch [5] - Update reserved memory map
Patch [6,7] - Add PAS/MSA modem nodes
