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.
Egbert Eich (4):
disk/iso: Add Support for block sizes > 512 byte to ISO partition
support
fs/fat: Don't multiply fatsize with sector size
part/dev_desc: Add log2 of blocksize to block_dev_desc data struct
fs/ext4: Support device block sizes != 512 bytes
