[U-Boot] [PATCH v2 08/33] drivers: ifc: dynamic chipselect mapping support

7 Oct 2018

From: Pankit Garg pankit.garg@nxp.com
IFC driver changes to implement the chipselect mappings at run time.
Defines init_early_memctl_regs and init_final_memctl_regs with
chipselect dynamic mapping for nor and nand boot.
