For LSI Host Bus Adapter (HBA) firmware, what is the difference between IT mode and IR mode?
The two firmware types are Initiator Target (IT) and Integrated RAID (IR). IR is the typical hardware RAID firmware that the internal cards or boards ship with.
The IT firmware, on the other hand, is the Initiator Target firmware which is designed to allow a SAS HBA to connect to up to 256 devices using SAS Expanders. The IT firmware is typically shipped on external cards. The IT firmware does not have any RAID capabilities and simply acts as an HBA.
Basicly the IT firmware is only just a HBA and the boot up time is quick. The IR firmware is the raid software firmware so boot up is a bit longer than having the IT firmware only. You can cross flash with the LSI firmware in IT mode only or IT and IR mode which is default in LSI. If you are going with pure software raid then the IT firmware is best.
mii - MII utility commands
mii device - list available devices
mii device - set current device
mii info - display MII PHY info
mii read - read MII PHY register
mii write - write MII PHY register
mii dump - pretty-print (0-5 only)
Addr and/or reg may be ranges, e.g. 2-7.

I use the RealView compiler to write my embedded application and added the retarget.c file to route the I/O routines to a physical UART interface.
But when I build the project, I get the following error:
Error: L6200E: Symbol __stdout multiply defined (by retarget.o and stdio.o).
What causes this error?
The retarget.c file allows you to use simple I/O functions such as printf or getline. When your application uses other complex functions such as fprintf, assert, fopen, fclose, etc., you get this error message.
Remove these function calls (or replace them with components from the Real-Time Library (RL-ARM).
