Introduce software mailbox driver, which enables the BMC to communicate with the Root of Trust (RoT) over an I2C target interface. Execute the following command at the BMC prompt to verify SWMBX functionality: - Verify the SWMBX address: aspeed-pfr-tool -w 0x13 0x8 aspeed-pfr-tool -r 0x13 [Expected output: 0x8] - Verify the protected SWMBX address: aspeed-pfr-tool -w 0x12 0x8 aspeed-pfr-tool -r 0x12 [Expected output: 0x0] - Verify the notify functionality: aspeed-pfr-tool -w 0x13 0x8 On Ast1060 console, you should see [NOTIFY] SWMBX: notify triggered on port 0 addr 0x13 - Verify the FIFO functionality: aspeed-pfr-tool -w 0xd 0x1f aspeed-pfr-tool -w 0xd 0x2f aspeed-pfr-tool -w 0xd 0x3f aspeed-pfr-tool -r 0xd aspeed-pfr-tool -r 0xd aspeed-pfr-tool -r 0xd aspeed-pfr-tool -r 0xd [Expected output: 0x1f, 0x2f, 0x3f, 0x0] Signed-off-by: Steven Lee <[email protected]>

Introduce software mailbox driver, which enables the BMC to
communicate with the Root of Trust (RoT) over an I2C target interface.
Execute the following command at the BMC prompt to verify SWMBX functionality:
Verify the SWMBX address:
aspeed-pfr-tool -w 0x13 0x8
aspeed-pfr-tool -r 0x13
[Expected output: 0x8]
Verify the protected SWMBX address:
aspeed-pfr-tool -w 0x12 0x8
aspeed-pfr-tool -r 0x12
[Expected output: 0x0]
Verify the notify functionality:
aspeed-pfr-tool -w 0x13 0x8
On Ast1060 console, you should see [NOTIFY] SWMBX: notify triggered on port 0 addr 0x13
Verify the FIFO functionality:
aspeed-pfr-tool -w 0xd 0x1f
aspeed-pfr-tool -w 0xd 0x2f
aspeed-pfr-tool -w 0xd 0x3f
aspeed-pfr-tool -r 0xd
aspeed-pfr-tool -r 0xd
aspeed-pfr-tool -r 0xd
aspeed-pfr-tool -r 0xd
[Expected output: 0x1f, 0x2f, 0x3f, 0x0]
