Cover letter [PATCH v2 0/9] Split region permissions into M-mode and SU-mode
This is first series in the series of forthcoming patches that would add support for different access permission for different sections of OpenSBI (RO, RX, RW). Eventually, this would lead to support of smepmp extension.
This patch series splits the current R/W/X permissions to M-mode R/W/X and SU-mode R/W/X. The split is in such a way that current permission semantics are not broken
Changes in v2:
1. Fixed the grammatical mistakes in the commit log.
2. Removed the white space new line from sbi_domain.h
3. Added enforce permission bit[6] details to documentation
