- The ROM text and data sections share the address range
(see SOC_I/DROM_MASK_LOW - SOC_I/DROM_MASK_HIGH).
- Initially, we had two PMP entries for this address range - one marking the
region as RX and the other as R.
- However, the latter entry is redundant as the former locks the PMP settings.
- We can divide the ROM region into text and data sections later when we
define boundaries marking these regions from the ROM.
