As in SAMA5D4 SoC, the gf table in ROM code can not be seen. So, when we try to use PMECC, we need to build it when do initialization. Add a macro NO_GALOIS_TABLE_IN_ROM in soc header file. If it is defined we will build gf table runtime.
The PMECC use the BCH algorithm, so based on the build_gf_tables() function in lib/bch.c, we can build the Galois Field lookup table.
