Storage devices with more than 2TB generally use blocksizes of 4096 bytes, So far u-boot was unable to boot from those devices as block sizes were hard coded to 512 bytes.
This patchset adds support for blocksizes != 512 byte to: - the ISO partition table. - the ext4.
To be useful, one most likely needs: "disk/gpt: Fix GPT Partition handling for Blocksize != 512" which was posted earlier.
With those fixes in place u-boot loads the kernel and initrd flawlessly from an ext2 fs on my 3TB USB hard drive which is set up with a GPT.
I've also reviewed the FAT code, it seems to be ok already (except for a bug that I came across).
I may be persuaded to take a shot at other fs which are supported by a vanilla Linux kernel and I thus can test.
