powerpc/b4860qds: Slave module for boot from SRIO and PCIE
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.
