IFC_MODE in RCW for T104x

[debduttabanerje]

Reset configuration word (RCW) source is specified through cfg_rcw_src[0:8]. then what is the use of RCW[203:211] IFC_MODE?

How to set the value of IFC_MODE? For ex. I want to boot my custom board based on T1022 from 8KB Nand flash, 128 pages/block. So I set cfg_rcw_src[0:8}=1_0100_0000. What should by the value of IFC_MODE in RCW?

Also since cfg_rcw_src has precedence over configuring the IFC, when these two values can be different?

When IFC controller (NOR or NAND) is selected by the cfg_rcw_src[0:8] value of the RCW[203-211] IFC_MODE is don't care.

The IFC_MODE is used, for example, when RCW and PBI are taken from SD card and U-Boot is booting from NOR or NAND.
