This patch turns on the SYS and BAT monitoring filters, and checks if the battery
meets the BAT OK threshold. If it doesn't, which is the case if the battery is
not present, it disables the "indicator" (eg, LED, vibrator) stuff and holds the
CPU at 200MHz during the boot into Linux.
This allows the GTA02 A6 here to boot with no battery up to the point it is
going to bring up backlight, and this with 100mA limit on USB at PMU. Enabling
the threshold filters for battery and SYS seems to have been critical in
getting any stability with this.

tty0 is the LCM... this patch changes the defaults so that the kernel
always treats tty0 as a console, but it also sets the loglevel so that
only KERN_ERR or worse will be printed there. With matching changes
to the kernel, most of the noise at KERN_ERR is reduced to KERN_INFO,
so it gets the behviour the LCM by default is not cluttered with
messages unless they are important during boot.

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.

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.

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).
