This series fixes PMP address alignment to comply with the RISC-V
specification WARL (Write-Any, Read-Legal) semantics.
When configuring pmpcfg (TOR, NA4, or NAPOT) and pmpaddr, if the
value is smaller than the PMP granularity, it needs to be aligned
to the PMP granularity.
Changes in v3:
- Use ROUND_UP() macro for NAPOT address alignment
Changes in v2:
- Fixed commit message grammar ("it needs to be aligned")
- Use ROUND_DOWN() macro for TOR address alignment to improve
code readability
Jay Chang (2):
target/riscv: Align pmp size to pmp-granularity
target/riscv: Use macros for PMP address alignment
