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.
What kind of ucode is this?  Fman or QE?
[Liu Gang-B34182] Right now the ucode is for Fman.
...


/* configure inbound window for slave's ucode */
printf("SRIOBOOT - MASTER: Inbound window for slave's ucode; "
"Local = 0x%llx, Srio = 0x%llx, Size =
0x%x\n",
(u64)CONFIG_SRIOBOOT_SLAVE_UCODE_LAW_PHYS,
(u64)CONFIG_SRIOBOOT_SLAVE_UCODE_SRIO_PHYS,
CONFIG_SRIOBOOT_SLAVE_UCODE_SIZE);
out_be32((u32)&srio->riwtar3 + CONFIG_SRIOBOOT_MASTER_PORT *
0x200,

These should be "(void *)" instead of "(u32)".
[Liu Gang-B34182] Thanks very much!
