When a b4860qds 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.
