*
* TOR: Each 32-bit pmpaddr# register defines the upper bound of the pmp region

* pmpaddr# register. In the case of pmpaddr0, the lower bound is address 0x0.

*
* NAPOT: Each 32-bit pmpaddr# register defines the region address and the size
* of the pmp region. The number of concurrent 1s begging at the LSB indicates
* the size of the region as a power of two (e.g. 0x...0 = 8-byte, 0x...1 =
* 16-byte, 0x...11 = 32-byte, etc.).
