The generic SCSI code in U-Boot was only aware of the READ CAPACITY (10) SCSI
command which can detect the size of disks up to 2TB in size. If that size is
exceeded, it should then try the READ CAPACITY (16) command which returns a
64 bit block count value.
BUG=chrome-os-partner:8180
TEST=In conjunction with the next change, built and booted into ChromeOS on
the Emerald Lake 2 CRB with a 250 GB SSD. Did the same but forced the READ
CAPACITY (10) command to saturate and the code to fall back to READ CAPACITY
(16). Note that this code has not be tested with a real SCSI disk, just the
AHCI code pretending to be a SCSI disk as it historically has.

Right now our code makes the assumption that there always is one
SCSI drive in the system (the AHCI attached SDD). However, this
might not be the case.
This patch prevents vboot from using an uninitialized disk entry
when instead it should go into recovery mode.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
