0020

After GPU power and clocking are available, the SMC starts seqUnReset which releases the GPU from reset. It then waits for the GPU to assert GPU_RST_DONE. If the GPU_RST_DONE signal is not asserted in the time allotted, EC_BOOT will be reported. The SMC will retry 4 more times. If on the final attempt, GPU_RST_DONE is still not asserted, the SMC remains in EC_BOOT and the 0020 code is displayed on the front panel.
