Ok, I'm using the X-Loader from git://git.igep.es/pub/scm/x-loader.git, tag v1.4.4-3, on top of which I apply http://git.free-electrons.com/training-materials/plain/lab-data/sysdev/u-boot/x-loader-1.4.4-3-igep-nand-support.patch to add support for the NAND-based IGEPv2 rev6. In terms of U-Boot, I use U-Boot 2011.12, on top of which I apply http://git.free-electrons.com/training-materials/plain/lab-data/sysdev/u-boot/u-boot-2011.12-igep-nand-support.patch to add support for the NAND-based IGEPv2 rev6. To make things easier if you don't need to rebuild those, I've put online pre-built binaries of X-Loader and U-Boot I'm using: http://free-electrons.com/~thomas/pub/igep-serial-problem/.
