of the hash framework, accumulative hashing was not supported. To work around this limitation, commit 5cd7d85 introduced an iov_cache array to store all the hash data from firmware. Once the ASPEED HACE model collected all the data, it passed the iov_cache to the hash API to calculate the final digest. However, with commit e3c0752, the hash framework now supports accumulative hashing. This allows us to refactor the ASPEED HACE model, removing redundant logic and simplifying the implementation for better readability and maintainability. As a result, the iov_count variable is no longer needed—it was previously used to track how many cached entries were used for hashing. To maintain VMSTATE compatibility after removing this field, the VMSTATE_VERSION is bumped to 2 This cleanup follows significant changes in commit 4c1d0af4a28d, making the model more readable. - Deleted "iov_cache" and "iov_count" from "AspeedHACEState". - Removed "reconstruct_iov" function and related logic. - Simplified "do_hash_operation" by eliminating redundant checks.

As a result, the FW gets stuck waiting for a completion signal from the HACE module. Additionally, in do_hash_operation, if an error occurs within the conditional statement, the HASH_IRQ bit is not set in the status register. This causes the firmware to continuously send HASH commands, as it is unaware that the HACE model has completed processing the command. To fix this, the HASH_IRQ bit in the status register must always be set to ensure that the firmware receives an interrupt from the HACE module, preventing it from getting stuck or repeatedly sending HASH commands.

To align with the recent U-Boot changes, where the Main Control Register's BIT16 is checked to skip the dram_init() process, this patch sets BIT16 in the SDMC Main Control Register at reset time. This allows both the main U-Boot stage to correctly detect and bypass DRAM initialization when running under QEMU.

BIT[6] (SCU_FREQ_DONE) indicates the measurement is finished. Firmware polls BIT[6] to determine when measurement is complete. The flag can be cleared by writing BIT[1] to 0. To simulate this hardware behavior in QEMU: If BIT[1] is set to 1, BIT[6] is immediately set to 1 to avoid firmware hanging during polling. If BIT[1] is cleared to 0, BIT[6] is also cleared to 0 to match hardware semantics. The initial value of this register is initialized to 0x80, reflecting the default value confirmed from an EVB register dump.

The tests verify: - That SCU protection registers can be unlocked and locked again - That modifying the primary protection register on AST2600 also affects the secondary one - That writes to protected SCU registers are blocked unless protection registers are unlocked explicitly These tests ensure proper emulation of hardware locking behaviour and help catch regressions in SCU access logic.
