The gfxRAM has no ECC, but it is 512KB in size. The other ECC SRAM comes in two banks of 256K each. The HAB uses parts of the 2nd bank and it seems that loading from the SD card may not exceed a bank size (256k-32k boot offset = 224k). U-boot since v2014.04 are larger than this and do not boot by default.
As U-Boot relocates to DDR3 the gfxRAM is probably reliable enough. However, an SPL framework would be better.
