I agree with Murali here. The cpu_is_ checking in the patch is going to quickly turn ugly as new SoCs with power domain control are added. On SoCs where domain power up procedure is not documented, even bootloader cannot be responsible for powering up the domain. The domain will be powered up in hardware itself; so the power domain status cannot show the domain as powered off. A better change in this area would be to add a timeout to the infinite loop reading epcpr. This will enable proper error reporting.
