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.
