Daniel Jobson 690bb53267 Introduce new bit to mark ROM as non-executable ... This is dynamically set by hw in system_mode_ctrl. ROM will reset to executable, but will be marked as non-executable as soon as we are no longer executing in ROM, like system_mode. ROM will be marked as executable again, if function calls are made to either `syscall_addr_reg` or `blake2s_addr_reg`. Set reset value of `blake2s_addr_reg` to an illegal address, halting the CPU if it is called unset. The blake2s function is 4-byte aligned, to ensure the cpu_addr is is aligned with the address in the register. Co-authored-by: Mikael Ågren <mikael@tillitis.se>		2024-12-09 09:36:57 +01:00
