powerpc/t4qds: Slave module for boot from SRIO and PCIE
When a T4 board boots from SRIO or PCIE, it needs to finish these processes: 1. Set all the cores in holdoff status. 2. Set the boot location to one PCIE or SRIO interface by RCW. 3. Set a specific TLB entry for the boot process. 4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot. 5. Set a specific TLB entry in order to fetch ucode and ENV from master. 6. Set a LAW entry with the TargetID one of the PCIE ports for ucode and ENV. 7. Slave's u-boot image should be generated specifically by make xxxx_SRIO_PCIE_BOOT_config. This will set SYS_TEXT_BASE=0xFFF80000 and other configurations. For more information about the feature of Boot from SRIO/PCIE, please refer to the document doc/README.srio-pcie-boot-corenet.
