fsl_ifc: Add the workaround for erratum IFC A-003399(enabled on P1010)

Poonam Aggrwal authored 13 years ago

Issue: Address masking doesn't work properly.
When sum of the base address, defined by BA, and memory bank size,
defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask
CSPRn[BA] bits.

Impact:
This will impact booting when we are reprogramming CSPR0(BA) and
AMASK0(AMASK) while executing from NOR Flash.

Workaround:
Re-programming of CSPR(BA) and AMASK is done while not executing from NOR
Flash. The code which programs the BA and AMASK is executed from L2-SRAM.
