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

[Hitz, Christian]

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?

Regards,
Christian
