When boot from SRIO, slave's ucode can be stored in master's memory space, then slave can fetch the ucode image through SRIO interface. For the corenet platform, ucode is for Fman. Master needs to: 1. Put the slave's ucode image into it's own memory space. 2. Set an inbound SRIO window covered slave's ucode stored in master's memory space. Slave needs to: 1. Set a specific TLB entry in order to fetch ucode from master. 2. Set a LAW entry with the TargetID SRIO1 or SRIO2 for ucode.
