[U-Boot] [Patch v2, batch 3 03/17] fsl_ifc: add support for different IFC bank count

25 Mar 2013

From: Mingkai Hu Mingkai.hu@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.
