Allow a board to "indicate" events if it likes on whatever it has
On GTA02 we light AUX during boot and run the vibrator briefly when we
skip a partition or device.

Despite what the docs say, steppingstone is always resident at
0x40000000 on s3c2442, this patch changes our linker script to
stick all steppingstone code there. The mapping of steppingstone
at 0x0 is broken by OM[] bus change dynamically caused for example
by GTA02 AUX button actuation.

Recent addition of append and noboot file checks broke NAND

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.

We dedicate 256MB for bootloader in GTA03 SD image, but actually they're
around 25KB currently. Reduce the stage2 pull to 32KByte.

This patch changes Qi to insist to fetch device-specific kernels from
filesystems that have named kernels. The kernels looked for are now
called
GTA01: /boot/uImage-GTA01.bin
GTA02: /boot/uImage-GTA02.bin
GTA03: /boot/uImage-GTA03.bin
This is part of the support for single rootfs that can be run on
multiple devices with correct kernel and module handling by the
bootloader.

The hack to find the number of sectors turns out to be
sensitive to the host kernel. This is a workaround until
we find something in /proc or /sys that has the same info
in a more accessible way.

The first revision for GTA03 A1 is "1", but we only populated
the info for revision 0.

We don't have card detect connected. Try to fake it better by
enabling the peripheral fuction to the ball and forcing pulldown
(card detect is active-low).

Prefer GTA03, enable dual mDDR init (killing SMDK compatability for now)

This gives compatability with SD Cards using the old U-Boot scheme of an initial
VFAT part for kernel and then ext2. If you put the kernel you actually want to
use in /boot/uImage.bin in the ext2 partition, it can boot these cards then.

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.

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.
