[PATCH v5 0/3] Renesas RZ/Five add support to configure PMA and add vendor specific SBI extension

[Lad Prabhakar]

Hi All,

This patch series aims to add support to configure the PMA regions present
on the Andes AX45MP core (andes45-pma.c which can be shared with other
Andes vendors) and configures the required PMA region for RZ/Five SoC.

This patch series also adds the SBI vendor extension
RENESAS_RZFIVE_SBI_EXT_IOCP_SW_WORKAROUND to check if IOCP is present on
the core and if un-available it also checks if SW workaround for cache
management needs to be applied.
