Some of utils.c isn't used until the full Qi image has been loaded into
memory, to save space in 4K steppingstone case on 2442, we split utils.c now
so only the interesting routines for steppingstone time take up space there.

We need putc even when we are operating entirely from steppingstone.
Arrange that the board-specific putc code is in a section that goes into
steppingstone, and adapt the utils.c putc() so that it no longer needs to
indirect through the board_api struct that is in main memory.

We want utils stuffs in steppingstone part, it's too expensive to have
CRC32 in there. Bust it out into its own file that appears only in
everything_else section in second bootloader stage.

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.

Moves various .h into include from drivers
Gets glamo-mmc.h working so we can detect
card ID / Size if the card is plugged in.
Adds FAT / MMC kernel source entry for GTA02 that
is first before the NAND one. When it works it will
favour to boot off SD Card if a kernel is found there, but
right now we don't have a working filesystem parser and
partition handling hooked up.

Move serial.c into drivers/serial-s3c24xx.c and qi-serial.h into include/serial-s3c24xx.h
making things a bit cleaner for being s3c24xx-specific. This needed a lot of meddling
additionally, ending up with a new puts() callback that belongs in the board structure
and removal of the debug uart member, since the puts() action was the only user.
Also change serial init API name and function to only fix to 115kbps and adapt to
PCLK.

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
