[U-Boot] [PATCH 03/21] fsl_ifc: add support for different IFC bank count
York Sun

Fri Mar 22 18:23:54 CET 2013
From: Mingkai Hu <Mingkai.hu at freescale.com>
Calculate reserved fields according to IFC bank count
1. Move csor_ext register behind csor register and fix res offset
2. move ifc bank count to config_mpc85xx.h to support 8 bank count
There's no IFC controller instead of eLBC controller on some platforms,
such as MPC8536, P2041, P3041, P4080 etc, so there's no macro definition
for the number of IFC chip select(CONFIG_SYS_FSL_IFC_BANK_COUNT) which
is used in the IFC controller header file fsl_ifc.h on these platforms.
