The fdisk and mkfs was factored out into a shell function
so that it is easier to create dirfferent partition layouts.
The default case was left the same as the original script
The partitions can be specified as percentages of the
available space (after Qi reserved space has been taken out)
by providing a comma separated list of values:
e.g. 25,0,50
Which would create partitions 1 and 3 with 25% and 50%
of the usable capacity. Partitions 2 and 4 would not be
assigned.

s3c6410 defaults to all clocks up, this leads to 120mA idle current at 5V.
Gating all the unused clocks off gets us down to 76mA idle current at 533Mhz
CPU clock down to 133MHz only helps by a further ~1.5mA.
During these tests camera unit was active with no camera attached, no EDGE.

Hello Andy,
I am in the process of making a modified 6410-partition.sh
and I wonder if there is a mistake in the VFAT partition size:
Shouldn't the "+ $REARSECTORS" in the FATSECTORS calculation
be a subtraction, otherwise the backupfs will overlap the
space reserved for Qi at the end of the SD Card.
Please look at this dif to see what I mean:
Hi Andy,
Sorry, previous patch to enable reset function of LCM is not working
stably somehow. :(
Since it's pin configuration is input. Attached patch is to set LCM
reset pin as output.
Cheers,

There's no trailing space after the last mac address addition, it
was broken before the recent patch adding the second mac address.
Also, we don't need to add the first space by hand if it's unconditionally
added in the string afterwards.

Because of this patch I can no longer load g_ether module with host_addr= and
dev_addr= parameters.
The module is always loaded using factory mac for HOST and random mac for DEV.
That messes up my setup a bit, as I use NetworkManager 0.7 on FreeRunner
itself (and it expects DEV mac to be the same each time).
Would it be a problem to also include g_ether.dev_addr?
Attached patch solves my problem.

There's one more thing that wants dynpart computed block offset -
the kernel offset used for NAND boot.
This patch moves the business end of the dynparts computation into
the port_init_gta02() so it's done earlier, and writes the block
index into the board_api struct NAND option's partition block start
field.
It also adds a field to the nand_dynparts struct so we can hold both
the true length and true block offset for each partition for later
use by the original code in append_device_specific_cmdline_gta02.

Now everything else is in place, we are able to mount
the GTA02 "identity" partition and extract the USB Ethernet
MAC Address from it, and add it to the kernel commandline.
This causes the Ethernet gadget to use the same MAC address
each boot, simplifying DHCP server situation. The MAC
address in the identity partition is globally unique from
the factory.

Previously we insisted on NAND block granularity read addressing
and buffer length, even though we normalized the block indexing to
512 bytes to be compatible with ext2 and SD.
This patch improves the read functions so they are completely 512-
block friendly, any number of 512 byte blocks can be fetched from
any 512 byte boundary now.

This adds dynamic partition computation support for Qi on GTA02.
It's for compatability with existing GTA02 using U-Boot partition
scheme where a bad block in the previous partition moves on the
start of the next partition by one block.
It's important that Qi has no private state, so we need to compute
the NAND arrangement each boot. It turns out this is extremely fast
using Qi's bad block code originally from Xinagfu.

Changes in the last couple of weeks aimed at cleaning this
code broke the block device init cache logic. This patch
restores the logic and reduces the card init failures when
there is no SD Card present to 1 regardless of the number
of partitions probed on the card.
Together with the reduction in Glamo card wait on init this
reduces the delay before trying NAND to 1/9th of before the
patches.

3000 retries is a very long time for an SD card to wake up,

On ext2 the symlink can be stored in inode itself if it's not larger than
60 bytes. If the symlink path is exactly 60 bytes, then one more byte is
needed to store terminating NULL, therefore the path is placed in a
separate block.
The PMU initializes all GPIOs to inputs in NoPower, including GPIO2,
which drives GSM_ON and has an external pull-up. Furthermore, we may
have entered PMU.Standby with the modem up.
Unlike u-boot, qi didn't initialize the GPIOs. With this patch is
does.

On the devices where we have only 2 physical buttons, one of those buttons
(i.e. POWER) is connected directly to PMU. The other button (AUX) is
connected directly to S3C pin and we can get its state immediately, it is
currently used to skip a boot possibility. To allow user to debug boot
problems we can use the POWER button, but we cannot poll for it too many
times as it slows down the boot considerably, therefore a dedicated
function is needed.
Finally all the restructuring pays off: we can cleanly separate the
uImage loader from all the rest, which will make it easy to add
loaders for other kernel image formats.
