Note: I left behind lcd_bitmap in features.txt, because removing it
would require considerable work in the manual and the translations.

'swcodec' is now always set (and recording_swcodec for recording-capable
units) in feature.txt so the manual and language strings don't need to
all be fixed up.

Allow user to select cpu undervolt
There have been quite a few issues across the SANSA AMS line related
to CPU undervolting while most players show greatly increased runtime
some crash.
Rather than constanly upping the voltage we now have a
setting with a safe value for all players and the option for lower voltages
I plan to add a few other options here later such as disk
timings and maybe some other clocks/experimental settings
Added: Disk Low speed option for AS3525v2 devices cuts
frequency to 12 MHz from 24 MHz
Added: Disk Low speed option for AS3525v1 devices cuts
frequency to 15.5 MHz from 31 MHz
Added: I2c Low Speed AS3525 devices, should be bigger improvement for v1 devices
Fixed: Debug menu for AS3525v2 No SDSLOT frequency,
Showed IDE freq though it is unused
Added: DBOP and SSP underclocking affects display on v1/v2 respectively
Fixed: debug menu now has SSP frequency, and SSP_CPSR
Update: made settings menu more generic
Update: cleaned up code
Added: Clip v1 & Fuze v1 didn't have HAVE_ADJUSTABLE_CPU_VOLTAGE.
not sure why but, waiting on testing to confirm
Added: C200v2 and E200v2 devices and HAVE_ADJUSTABLE_CPU_VOLTAGE.
Fixed: v1 devices don't like display timing set lower (dbop)
v1 devices don't have a divider set for ssp (causes divide by 0)
Fixed: ClipZip display lags with Max SSP divider changed from 0xFE to 0x32
Fixed: v1 devices didn't work properly with highspeed sd cards
Added code from http://gerrit.rockbox.org/r/#/c/1704/
Added powersave and IDE interface enable/disable
Added: V2 devices now have powersave enabled on sd interface
Update: cleaned up code, lang defines, added manual entries
Update ssp clock mechanism added calculated ssp divider to clipzip
Update turn display clock off when clip+ turns off display
Fixed: clipzip wrong register for SSP clock

TODO: add other players?
Adds the ability to load firmware from other drives on MULTIVOLUME targets
Mihail Zenkov <mihail.zenkov@gmail.com> had posted a hard coded patch
to allow this on several Sansa players, I made it more universal
Redirect file rockbox_main.<name> should placed in root of
drive you would like to be main, if this file empty or there a single
slash '/' firmware will be loaded from /.rockbox in root of this drive
If instead a /<*DIRECTORY*> is supplied in rockbox_main.<name> then
firmware will be loaded from /<dir>/.rockbox/
NOTES*
The directory can have multiple levels however..
leading slash MUST be included
trailing slash can be omitted
(eg. /test/.rockbox would be simply '/test' in the redirect file)
Redirect file will not work on internal drive (whatever is default boot drive)
Volume with the highest index containing redirect file will be loaded
first.
Firmware file is checked for boot data region, if missing, firmware
image will not be loaded.
On failure or if no redirect file is found load will fallback to
internal drive
Currently only Sansa Fuze+, Sansa Clip+,
Sansa Clip Zip, Sansa Fuzev2, and Sansa Fuzev1 are implemented.
Players (with HAVE_MULTIVOLUME)
will need #define HAVE_BOOTDATA and #define BOOT_REDIR "rockbox_main.<name>"
added to their config file
boot_data is implemented in crt0.s file (See g#1552)
ARM and IMX233 have aleady been implemented
Once these conditions are met <HAVE_MULTIBOOT> will be defined by config.h
Partitions on the drives are able to have a redirect as
well.

With this changes rockbox can be loaded from SD card when internal storage
can't be mount (due to hardware or software problem).

Voltage is reduced when the CPU is unboosted, resulting in a large
reduction in power consumption. In analogy with the AMSv1 voltage
scaling code (currently disabled due to problems with SD cards),
I have defined a config file option to enable/disable it.
Change-Id: Ia89c31ec06dd012354b4d53435e7b5b36243b206
Voltage scaling is not yet enabled, but will follow once we are sure
these changes are stable. Preliminary testing suggests a large
increase in battery life, which will be further improved by voltage
scaling. Patch by Mihail Zenkov with help from myself and others on
the forums.

For some reason, the bootloader and config files didn't define
HAVE_BOOTLOADER_USB_MODE, also remove the special cases in usb.c which they
implied.
Change-Id: I68c29be7d03627e64cac4ff7678e0c211e087a8c
Except for unfinished or experimental ports, it isthe case that
USE_ROCKBOX_USB and HAVE_USBSTACK are both defined or both undefined.
Furthermore, it is a leftover of some early developments on the USB stack and
doesn't make sense anymore.

* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application)
to break powermgmt.c's assumption about the ability to read battery voltage.
There's now additionally percentage (android) and remaining time measure
(maemo). No measure at all also works (sdl app). If voltage can't be measured,
then battery_level() is king and it'll be used for power_history and runtime
estimation.
* Implement target's API in the simulator, i.e. _battery_voltage(), so it
doesn't need to implement it's own powermgmt.c and other stubs. Now
the sim behaves much more like a native target, although it still
changes the simulated battery voltage quickly,
* Other changes include include renaming battery_adc_voltage() to
_battery_voltage(), for consistency with the new target functions and
making some of the apps code aware that voltage and runtime estimation
is not always available.

Fix problems with volume of recorded material by converting 14-bit samples to
16-bit. Remove duplicate samples from recorded data and support proper
samplerate since ADC runs 1/2 the codec clock. Support monitoring mono on both
output channels by feeding data manually to I2SOUT under the right conditions.
DMA is no longer used for recording since frames must be processed as described
above but it does allow full-duplex audio.
Miscellaneous change includes a proper constant (HW_SAMPR_DEFAULT) to reset the
hardware samplerate when recording is closed. PP5024 and AS3525 have different
default recording rates (22kHz and 44kHz respectively) but both have half-speed
ADC.
