The BCMBCA broadband SoC integrates the NAND controller differently than STB, iProc and other SoCs. It has different endianness for NAND cache data.
Add a SoC read data bus shim for BCMBCA to meet the specific SoC need and performance improvement using the optimized memcpy function on NAND cache memory.
This is a port of the upstream Linux patch to U-Boot.

The patch looks fine, but shouldn't the existing brcmnand_read_data_bus() in drivers/mtd/nand/raw/brcmnand/brcmnand.c also be replaced with brcmnand_soc_data_bus_read()?
Maybe this is a problem in the upstream kernel driver though :/
