[U-Boot] 4-bit ECC (BCH) support for NAND

Hi,

we are looking to change the NAND flash part on our custom board (AT91SAM9G20-EK based). The new part requires at least a 4-bit ECC algorithm (e.g. BCH). As our processor has no hardware ECC capabilities the ECC has to be calculated in software.

The Linux kernel has support for BCH ECC since 2.6.39. Has U-Boot support for this kind of ECC algorithm? E.g. Could we use U-Boot to write a kernel and rootfs with matching ECC into the flash?
