[U-Boot] [PATCH v2 0/4] Add Support for Storage Devices with Blocksizes != 512

[Egbert Eich <egbert.eich@gmail.com>]

From: Egbert Eich <eich@suse.de>

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
