This patch adds firmware dump support for marvell
bluetooth chipset. Currently only SD8897 is supported.
This is implemented based on dev_coredump, a new mechnism
introduced in kernel 3.18rc3
Firmware dump can be trigger by
echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcd*/data
We have prepared following script to divide fw memory
dump data into multiple files based on memory type.
[root]# cat btmrvl_split_dump_data.sh
#!/bin/bash
# usage: ./btmrvl_split_dump_data.sh dump_data
fw_dump_data=$1
mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST"
for name in ${mem_type[@]}
do
sed -n "/Start dump $name/,/End dump/p" $fw_dump_data > tmp.$name.log
if [ ! -s tmp.$name.log ]
then
rm -rf tmp.$name.log
else
# Remove the describle info "Start dump" and "End dump"
sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
if [ -s /data/$name.log ]
then
echo "generate /data/$name.log"
else
sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
echo "generate /var/$name.log"
fi
rm -rf tmp.$name.log
fi
done

A vendor specific command is sent to firmware during
initialization to enable this feature. This command is for
SD8897 only.

For SD8897, CMD52 write_to_clear may have missing interrupts
under certain corner case condition. Use CMD53 read-to-clear
to fix the problem.

Some ARM versions of Chromebook need to download a new calibration
data from host driver to firmware. They do have EEPROM but still
need a piece of new calibration data in test mode.
The cal-data is platform dependent. It's simpler and more feasible
to use device tree based cal-data instead of configuration file
based cal-data.
This patch remove configuration file based cal-data downloading
and replace it using cal-data from device tree.
When CONFIG_OF is not selected, or the specific property is not
present in the device tree, the calibration downloading will not
happen.

A text file containing calibration data in hex format can
be provided at following path:
/lib/firmware/mrvl/sd8797_caldata.conf
The data will be downloaded to firmware during initialization.

The SD8787 firmware image is shared with mwifiex driver.
Whoever gets loaded first will be responsible for firmware
downloading.

The driver uses "u32" for alignment check and calculation which
works only on 32-bit system. It will crash the 64-bit system.
Replace "u32" with "unsigned long" to fix this issue.

The Marvell Bluetooth SDIO driver has a really complicated concept on how
firmware names are assigned to specific device ids. Fix that by doing a
proper structure and assign it to the module device table.
And while at it fix various coding style weirdness that is still present
in this driver.

Both header files of the Marvell Bluetooth driver are private anyway and
if the driver happens to include them twice or they create a circular
dependency then the driver needs fixing. So just remove both pointless
ifdefs.

This driver supports Marvell Bluetooth enabled devices with SDIO
interface. Currently only SD8688 chip is supported.
The helper/firmware images of SD8688 can be downloaded from this tree:

This patch incorporates a lot of comments given by
Nicolas Pitre <nico@marvell.com>. Many thanks to Nicolas Pitre.
