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)
fix bugs in GPIO register offsets, set loglevel=8 for GTA03

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.

This adds the memory testing code to Qi. It tests the range of memory with
several constants and then a 32-bit walking 1 pattern, and repeats forever.
The entire main SDRAM can be tested due to the fact this runs out of
steppingstone only and does not need to store anything outside of it.
It introduces a steppingstone-based stack for use entirely in steppingstone.

Improve glamo-mmc so that it uses MMC_READ_MULTIPLE_BLOCK and copes with
64 blocks in one command (and STOP sent after each set), instead of sending
a new command per-block

Little cleanup and new code that collects and defers contiguous sector reads
into one potentially more efficient larger sequential read action.
This matters for example on SD Card protocol.

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.

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

This patch adds a small script that knows how to partition, format and
prepare with a bootloader image an SD Card for usage with SD Card boot
on 6410.
You use it like this:
./6410-partition-sd.sh sde sdhc ./image/qi-s3c6410-andy_495294c60f2f1432
This will prepare your card with three partitions and put the bootloader
images at the end as required by 6410 iROM.
If you put anything on the fourth parameter, it skips the fdisk and the
formatting stages and just updates the bootloader.
