[PATCH 0/2] MediaTek SCP: Urgent fixes for all MTK SoCs

This series brings some missing validation for the IPI buffer size
that is read from the firmware retrieved from userspace: if the FW
declares IPI buffer offset starting at an out of range address, the
driver doesn't do any validation and naively goes on with IO R/W
operation.

That poses various risks which I believe I really don't need to
describe, leaving it to the reader's imagination :-)

Please note that the first fix is URGENT.

P.S.: Of course, this was tested OK on multiple MTK platforms.

remoteproc: mediatek: Don't parse extraneous subnodes for multi-core
