[PATCH v1 7/8] hw/arm/aspeed_ast10x0: Wire SEC SRAM to the SBC model

[Jamin Lin <jamin_lin@aspeedtech.com>]

Pass the internal SEC SRAM region and its base address to the secure
boot controller (via the 'sram' link and 'sram-base' property) so its
ECDSA engine can read the public key, signature and digest that the
guest firmware stages there before triggering a verify.
