	Bit n -> SRAMSAn = 1 (NS).
bool	wtsc_ns
	SRAMSAR.SRAMWTSA bit.

	SRAMSABARn boundary value.

Detailed Description

TrustZone security attribution configured at init time.

Mirrors HUM Ch 58.2.2 "SRAMSAR" (p 3528) and HUM Ch 58.2.3 "SRAMESAR" (p 3529). Each per-bank flag, when true, marks the corresponding SRAM register set as Non-Secure. wtsc_ns marks SRAMWTSC as Non-Secure. ecc_region_ns marks the whole ECC region (across all banks) Non-Secure via SRAMESAR.

Boundary addresses for SRAMSABARn live in boundary_offset[bank] – one absolute offset per bank, 4 KB aligned per HUM Ch 58.2.1 (p 3527).
