Is it really correct to set last_block_init to the next entry ?
It would seem that the current (i.e., bogus) values are then just
used without further ado. Untested.

This puts the loop body in a new function called try_this_kernel.
As an added benefit, we can drop one level of indentation.
This change is hard to read as a patch. It gets better if one just
applies it and then looks at it with "git diff -w" or similar.

This adds two features that can be set in the rootfs that Qi is checking.
- if it finds /boot/noboot-<device>, eg /boot/noboot-GTA02 then it will
skip the rootfs for booting and try the next one if any
- if it finds /boot/append-<device>, eg, /boot/append-GTA02 then it will
append the contents of this file to the kernel commandline.

This makes a new behaviour for Qi, when there are no valid kernels then it
performs the memory test. It means you can either move kernels out of the way
to get the memory test, or make an SD Card just with normal Qi on it and no
kernels to get a memory test.

This heavily adapts the Samsung U-Boot hs_mmc code and combines it with the
SD / SDHC startup code written for glamo-mci stuff that is known to work OK
with common SD and SDHC.
tla01 is changed to use the implementation.

This patch makes qi source structure cpu-centric, and allows multiple CPUs
to be handled with the board definitions inside the CPU dirs.
You have to make a particular CPU version of Qi now, which you can do by
a shell command like this:
make clean ; make CPU=s3c2442 && make CPU=s3c6410
which gets you
$ ls -l image/

The 6410 support in there is enough to send a character "U" on the 6410 SMDK
Because the product naming is not defined, currently the device targeted for 6410
is called "TLA01"

This patch performs the equivalent init actions to the SDHC slow

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.

We have to minimally support DOS partition scheme.
Partitions are counted from 1+ now, and 0 means no
partition table instead of -1.

Giant patch:
- renames everything from kboot to qi
- changes filenames accordingly in several places
- fixes the linker script so stuff that does not execute
from steppingstone context has real linked addresses
in the relocated region, it means all code and pointers
work now outside first 4KBytes
- adds src/gta02/gta02.c to contain board-specific init and
other functions
- adds sophisticated structs to define most features in the
board-specific files, including board type detection,
board revision detection, and multiple kernel source
definition (NAND, SD FAT, SD ext2, etc), including auto
sequencing of trying the kernel sources in order (filesystems
and partition support not done yet)
- GTA02 detects itself by NOR presence and reports A5 / A6
- commandlines for kernel also come from board-specific
kernel source definitions so correct kernel commandlines
are provided depending on boot device -- on GTA02 now
boots NAND kernel into NAND jffs2 filesystem
- CRC32 is checked on loaded kernel image to make sure we
know about corruption in bootloader
