Now everything else is in place, we are able to mount
the GTA02 "identity" partition and extract the USB Ethernet
MAC Address from it, and add it to the kernel commandline.
This causes the Ethernet gadget to use the same MAC address
each boot, simplifying DHCP server situation. The MAC
address in the identity partition is globally unique from
the factory.

On ext2 the symlink can be stored in inode itself if it's not larger than
60 bytes. If the symlink path is exactly 60 bytes, then one more byte is
needed to store terminating NULL, therefore the path is placed in a
separate block.
Little cleanup and new code that collects and defers contiguous sector reads
into one potentially more efficient larger sequential read action.
This matters for example on SD Card protocol.

Naughty bug bug U-Boot ext2 implementation -- cut and paste of stanza above for
indir1 check used for indir2 but not all the check was not updated.
This removes hundreds of repeated reads of same sector during kernel load.

With large SDHC cards, the ext2/3 filesystem put on large partitions
by mkfs.ext2/3 is not how it used to be, it has a dynamic multiplier for
its block addressing. Without these changes, based on a patch by Ryan
Chen
http://lists.denx.de/pipermail/u-boot/2008-July/037786.html
we cannot parse large ext3 filesystem.

This patch performs the equivalent init actions to the SDHC slow
unitl first bulk patch in kernel, it allows us to work with large
SDHC cards which exceed Glamo timeout capability at 16MHz for first
access.

This adds ext2 support from U-Boot and stitches it into the
partition stuff. It also upgrades the board definitions so they
can define the path to look for in the ext2 filesystem being
mounted. I used /boot/uImage.bin because this is already in use
by the packaged kernel.
We now mount, open and pull the kernel from ext2 in phase2.c if
the kernel source defines it.
