[RFC PATCH v3 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.

RFC v2 -> RFC v3
-> Fixed review comments pointed by Lin-san
   * Used switch case macro
   * Added a check to verify the PMA size is power-of-2
   * Dropped un-needed calculation done in PMA code for NAPOT.
   * Dropped MISA macro
-> Fixed comments pointed by Himanshu
-> Fixed check patch issue

RFC v2 -> RFC v1
-> Fixed review comments pointed by Lin-san
-> Implemented PMA as library so that it can be shared

RFC v1:
https://patchwork.ozlabs.org/project/opensbi/patch/20221212094421.14556-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cheers,
Prabhakar
