Subject: [PATCH] explicitly-link-notes-section.patch
Since 2.6.23 kbuild produces a 3GB arch/arm/boot/Image because it includes a
.note.gnu.build-id section at address 0 which is followed by 3GB of 0x00.
The --build-id option is set in the toplevel Makefile.
This patch explicitly puts the notes section after the TEXT section.

[PATCH] support mtd NAND commandline partitions for S3C2410
This patch adds support for the mtd NAND core standard method of passing
partition table information from the bootloader into the kernel by using
the kernel commandline.
The board specific code can still manually override and provide a fixed
partition table, so this patch will behave backwards compatible.

fix-i2c-s3c2410-resume-race.patch
There is a nasty race between i2c-s3c2410 resume and resume of I2C
driver and the client drivers -- the watchdog device actually gets to
use the dead I2C bus before it is reinitialized by the I2C driver
resume! This patch makes sure any customers get turned away until
the shopkeeper has woken up.

The initialization of clocks uses mutexes, but we execute the resume in
an interrupt context. We therefore have to hand this task to a non-interrupt.

[PATCH] Add Kconfig option to enable NAND bad-block-table support for s3c2410
This patch adds a new CONFIG_MTD_NAND_S3C2410_BBT which, if enabled,
asks the mtd NAND core to use a bad-block table.

Subject: [PATCH] gta01-jbt6k74.patch
This driver adds support for the SPI-based control interface of the LCM (LCD
Panel) found on the FIC GTA01 hardware.
The specific panel in this hardware is a TPO TD028TTEC1, but the driver should
be able to drive any other diplay based on the JBT6K74-AS controller ASIC.

Subject: [PATCH] gta01-vibrator.patch
This patch adds driver support for the vibator device of the FIC/OpenMoko
Neo1973 GSM phone. The driver uses the existing LED class driver framework,
since there's a lot of similarity between the LED and the vibrator function.

Subject: [PATCH] s3c2410_udc-2440_dual_packet-workaround.patch
This is a patch that seems to make the USB hangs on the S3C2440 go away. At
least a good amount of ping torture didn't make them come back so far.
The issue is that, if there are several back-to-back packets,
sometimes no interrupt is generated for one of them. This
seems to be caused by the mysterious dual packet mode, which
the USB hardware enters automatically if the endpoint size is
half that of the FIFO. (On the 2440, this is the normal
situation for bulk data endpoints.)
There is also a timing factor in this. I think what happens is
that the USB hardware automatically sends an acknowledgement
if there is only one packet in the FIFO (the FIFO has space
for two). If another packet arrives before the host has
retrieved and acknowledged the previous one, no interrupt is
generated for that second one.
However, there may be an indication. There is one undocumented
bit (none of the 244x manuals document it), OUT_CRS1_REG[1],
that seems to be set suspiciously often when this condition
occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which
may have a function related to this. (The Samsung manual is
rather terse on that, as usual.)
This needs to be examined further. For now, the patch seems to do the
trick.
Note that this is not a clean solution by any means, because we
might potentially get stuck in that interrupt for quite a while.

Subject: [PATCH] pcf506xx.patch
Moved shared PMU code from pcf50606.h and pcf50633.h (which prevented inclusion
of both at the same time) to pcf506xx.h
- include/linux/pcf50606.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h
- include/linux/pcf50633.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h
Signed off-by: Werner Almesberger <werner@openmoko.org>

Subject: [PATCH] gta02-bt-fixes.patch
Modify GTA02 power manager for bluetooth.
1. Default power value isn't correct. Now we set pcf50633 LDO4 to 3.2 voltage.
2. Separate GTA01 and GTA02 source code.
3. Add pcf50633 API for enable register.

Subject: [PATCH] input-nots-mousedev.patch
This patch disables the reporting of touchscreen-like devices via
/dev/input/mice. In the Neo1973 (much like other handheld devices),
we need this to distinguish between the touchscreen (which uses tslib)
and optional additional usb/bluetooth mice that might be attached.

Fail the build noisily if "mkimage" can't be found, e.g., if we forgot to add
the u-boot directory to PATH.

Subject: [PATCH] introduce-fiq-basis.patch
Adds a C-based FIQ ISR which is very convenient (and unusual --
normally you have to do FIQ ISR in assembler only).
Based on my article:
http://warmcat.com/_wp/2007/09/17/at91rm9200-fiq-faq-and-simple-example-code-patch/
Implemented as a platform device and driver.
Suspend / resume is tested and works.

+/*
+ * Major Caveats for using FIQ
+ * ---------------------------
+ *
+ * 1) it CANNOT touch any vmalloc()'d memory, only memory
+ * that was kmalloc()'d. Static allocations in the monolithic kernel
+ * are kmalloc()'d so they are okay. You can touch memory-mapped IO, but
+ * the pointer for it has to have been stored in kmalloc'd memory. The
+ * reason for this is simple: every now and then Linux turns off interrupts
+ * and reorders the paging tables. If a FIQ happens during this time, the
+ * virtual memory space can be partly or entirely disordered or missing.
+ *
+ * 2) Because vmalloc() is used when a module is inserted, THIS FIQ
+ * ISR HAS TO BE IN THE MONOLITHIC KERNEL, not a module. But the way
+ * it is set up, you can all to enable and disable it from your module
+ * and intercommunicate with it through struct fiq_ipc
+ * fiq_ipc which you can define in
+ * asm/archfiq_ipc_type.h. The reason is the same as above, a
+ * FIQ could happen while even the ISR is not present in virtual memory
+ * space due to pagetables being changed at the time.
+ *
+ * 3) You can't call any Linux API code except simple macros
+ * - understand that FIQ can come in at any time, no matter what
+ * state of undress the kernel may privately be in, thinking it
+ * locked the door by turning off interrupts... FIQ is an
+ * unstoppable monster force (which is its value)
+ * - they are not vmalloc()'d memory safe
+ * - they might do crazy stuff like sleep: FIQ pisses fire and
+ * is not interested in 'sleep' that the weak seem to need
+ * - calling APIs from FIQ can re-enter un-renterable things
+ * - summary: you cannot interoperate with linux APIs directly in the FIQ ISR
+ *
+ * If you follow these rules, it is fantastic, an extremely powerful, solid,
+ * genuine hard realtime feature.

Subject: [PATCH] introduce-fiq-use-timer3-as-source.patch
This makes the FIQ stuff specific to one of the timers on the
s3c244x and adds the platform stuff for fiq in the gta02 init
Currently one sysfs node is exposed, a count of FIQ events

Subject: [PATCH] introduce-fiq-migrate-vibrator-gta02-only.patch
On GTA02 we use FIQ to manage the vibrator IO now. That
is necessary because we stole timer3 from doing hw pwm
for vibrator. This keeps the same UI in /sys but does
"bitbang pwm" on the same vibrator GPIO

Subject: [PATCH] gta01-dehang-printk.patch
This is a temporary work-around Mike Westerhof for this bug:
http://bugzilla.openmoko.org/cgi-bin/bugzilla/show_bug.cgi?id=788
See also
http://lists.openmoko.org/pipermail/openmoko-kernel/2008-February/000804.html
(It's the 2nd option.)
We may settle on a different solution in the future, depending on
feedback from upstream.

Subject: [PATCH] introduce-fiq-hdq.patch
This adds a platform driver and device which performs HDQ
battery protocol using a single GPIO pin which is set
through platform data.
HDQ has some hard latency requirements which can't
be met if interrupts are enabled, so normally using
a GPIO for this will require blocking out all other
interrupts and processes for several milliseconds
per register being read or written.
This HDQ protocol engine is a FSM implemented inside the
the FIQ ISR and regulated by timer interrupts happening
at 20us intervals. The path through the FSM on any
"clock" is very short and should be over with in ~
1us. Because FIQ has guaranteed latencies of <1us,
it means we can service the HDQ protocol without
blocking interrupts or any other process other than
the caller that is waiting for the result. It's pretty
cool performance from 1 GPIO ;-)
Due to it being hard to do locking from the FIQ ISR
the code simply sleeps 10ms or whatever the scheduler
gives it and checks if the transfer took place yet.
This platform driver doesn't have any knowledge about
the device it is talking to, it just knows it is a
HDQ device. It exports three functions for read, write
and confirming HDQ is initialized. It also exports two
/sys nodes that are usable by humans, one dumps the whole
127 register HDQ register space
# cat /sys/devices/platform/gta02-hdq.0/hdq/dump
00 44 55 00 00 00 ba 04 a2 0d 50 00 00 00 00 00

Subject: [PATCH] introduce-bq27000-battery-driver.patch
This is a driver for the bq27000 found in the Highcell A5
battery, and the platform device stuff for it for GTA02. It
is a Power Supply Class battery device.
The driver doesn't contain an HDQ engine but accepts pointers
from the platform data to the HDQ action routines; our
platform data plugs it into the FIQ HDQ engine stuff.
The Power Supply class exposes the battery down /sys so you
can find out battery status by doing the equivalent of this
bash command
for i in capacity charge_full current_now present status technology temp time_to_empty_now time_to_full_now type voltage_now ; do echo -n "$i " ; cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/$i ; done
Here is the kind of result you get from a battery discharging
capacity 0
charge_full 1215585
current_now 183375
present 1
status Discharging
technology Li-ion
temp 276
time_to_empty_now 0
time_to_full_now 3932100
type Battery
voltage_now 2761000
Note that temp is in 1/10 degrees C, other values are in uV,
uA, uW. The time_to_* reported are bogus, but that is what
the battery actually reports.
We can make more mappings to entries in power_supply class
but this is enough to get started with.

From adeb466de3bb306dc68468c64be3ebc61960d788 Mon Sep 17 00:00:00 2001
From: Andy Green <andy@openmoko.com>
Date: Fri, 25 Jul 2008 23:06:01 +0100
Subject: [PATCH] fix-glamo-mci-defeat-ops-during-suspend.patch
We need to be able to use the config option CONFIG_MMC_UNSAFE_RESUME that allows the rootfs
to live on SD. But when we use this, it tries to send a reset command to the SD card during
suspend -- and unfortunately many things like Power have suspended by then.
This patch again rejects IO on the MMC device during suspend of the MMC device, and it
gives the result the rootfs on SD card works okay.

Starting up all the PWMs seems to be needed for PWM3 operation
and FIQ / HDQ / VIB operation. But after starting, turn the
LEDs to GPIO-only.

Subject: [PATCH] introduce-usb-host-power-control.patch
Unless I really really missed the point, there is no support for enabling
USB Host power for USB host mode. This patch adds a /sys node for GTA02
that allows control of the charge pump for 5V out on the USB mini connector
It doesn't change any logical mode in the CPU, just enables (1) and disables
(0) USB host power.
