cd9906847b arm: Fix PortalPlayer linker scripts with binutils 2.21+
For reasons that are still unclear, the 'ncbss' region was overlapping
the "audiobuffer" when linked with 2.21, but okay with 2.20.

Fixed it by making the audiobuffer explcitly use the current position
instead of relying on it being implicit.

With this change, portalplayer-based targets generate working binaries
when built with binutils 2.21 or newer.

This bug also theoretically affects imx233/imx31 targets as they
also have NOCACHE_BASE games in their linker scripts, but I lack
access to one to test with.

5bd86eb4b4 pp502x: Don't fill the cache starting from address 0x0
The pp502x cache init code tries to flush the cache by reading
a block of DRAM.  Change the starting point from 0x0 to 0x1000
so the compiler doesn't helpfully insert an undefined instruction
to deliberately crash the target.

(This behavior is intentional on the part of GCC, and was triggered
 by using -Os with my experimental 4.9.4 toolchain)

7442742208 iPod Classic: disable IRAM1
On Classic, IRAM1 (second 128Kb of a total of 256KB available IRAM) is
slower than DRAM. Codecs that actually are using regions of IRAM1 runs
faster when DRAM is used, so IRAM1 is disabled and only IRAM0 remains
enabled: 48KB for core and 80KB for codecs/plugins.

The next test_codec results shows how decode time is decreased:

file           boosted     unboosted
*.ra           ~1.5%       ~0.5%
*.mpc          ~21%        ~4.5%
*.ogg          ~0.5%       ~0%
nero_he*.m4a   ~8%         ~1%
nero*.m4a      ~25%        ~7%
wmapro*.wma    ~4.5%       ~0%
wma*.wma       ~25%        ~7%

In addition there is a small power save when IRAM1 HW is disabled.

6f0320a953 As3525 v1/v2 Add power savings menu
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

dcd71e66bd Optimize lcd-ssd1303 driver (clip series)
Saves 100+ bytes (50 of it in iram), saves a bit of power

Internal LCD clock decreased but with added efficiency of drawing routines
loses only around 2 Hz on the scanrate (~75Hz) while fps is slightly increased

Column offsets are now calculated outside the loops saving a few instructions

Passing a LCD_NOP command after lcd_update turns off Data/Cmd# gpio
saving a bit more power

Added a function lcd_write_cmd_triple() that allows 3 commands to be sent at once
when enabled with LCD_USE_FIFO_FOR_COMMANDS it sends them back to back without
checking FIFO status in between or sending to thhe D/C# Gpio.
Makes an assumption about the FIFO being large enough to
accept 3 commands after being emptied which should be the case on the
clipv1, clipv2, clipplus. I have only enabled it for the clip plus
as thats the only device I have to test it on.

On clip+ the SSP clock is now turned off when screen is off

no way to read most of the debug menu items.

This patch makes the menu button scroll the text 1 character
to the right with each press and the center (select) button
re-aligns the text

Adds SSP frequency(v2) & register
Adds SD slot frequency(v2)

1f63604e2c Fuze PLUS Fix lcd_update_rect()
Lcd_update rect was hanging during horizontal screen update x = 238 and width = 2
which was within the bounds of the screen, this seems to be a weird corner case
but more testing needs done.

Update_rect now properly bounded between 0 - screen w/h
--Cleaned up code

Pixels in x are now multiples of 4.

Datasheet states:
-------------------------------------------------------------------------------------------
WORD_LENGTH=0 implies the input frame buffer is RGB 16 bits per pixel.
DATA_FORMAT_16_BIT field indicates if the pixels are in RGB 555 or RGB 565 format.
Limitations:
— BYTE_PACKING_FORMAT [3:0] should be 0x3 or 0xC if there is only one pixel per word.
— If there are two pixels per word, BYTE_PACKING_FORMAT [3:0] should be 0xF and
H_COUNT will be restricted to be a multiple of 2 pixels.

and

WORD_LENGTH=3 indicates that the input frame-buffer is RGB 24 bits per pixel (RGB 888). If
BYTE_PACKING_FORMAT [3:0] is 0x7, it indicates that there is only one pixel per 32-bit word
and there is no restriction on H_COUNT.
Limitations:
— If BYTE_PACKING_FORMAT [3:0] is 0xF, it indicates that the pixels are packed, i.e. there
are 4 pixels in 3 words or 12 bytes. In that case, H_COUNT must be a multiple of 4 pixels.
-------------------------------------------------------------------------------------------

We are using 16 bits per pixel and byte_packing = 0xF but device crashes with multiple of 2 pixels

Behaviour can be verified with plugin - oscilloscope, Horizontal mode device hangs as indicator
reaches right of screen

f4c4221306 Convert i.MX31 and AMS target to use RTC interrupt
Instead of checking ticks, set a sticky dirty flag that indicates
that the RTC needs to be read. This gives a timely update and more
accurate readout without actually reading the RTC until it changes.
The implementation should atomically read the flag and clear it.
Setting the flag would typically happen in an RTC tick ISR.

Still no floating point support if ever that would be desired.

* Width and precision: 'n', '.n', '*' and '.*'

* Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z'

* Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X'

(*) Provision exists to switch lesser-used stuff on or off or when
certain functionality isn't desired (bootloader?). The compulsory
radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length
modifiers being optional. The default setup is 'l', 'z', 'c', 'd',
'p/P', 's', 'u', 'x/X'.

* Move fdprintf() to its own file. It was in a strange place.

* Make callers compatible and fix a couple snprintf() bugs while
at it.

Could smush it down in size but I'm gonna get over the binsize
neurosis and just the let optimizer do its thing.

1654efc313 Unify storage threads into one
* Editing a bunch of drivers' thread routines in order to
implement a new feature is tedious.

* No matter the number of storage drivers, they share one thread.
No extra threads needed for CONFIG_STORAGE_MULTI.

* Each has an event callback called by the storage thread.

* A default callback is provided to fake sleeping in order to
trigger idle callbacks. It could also do other default processing.
Changes to it will be part of driver code without editing each
one.

* Drivers may sleep and wake as they please as long as they give
a low pulse on their storage bit to ask to go into sleep mode.
Idle callback is called on its behalf and driver immediately put
into sleep mode.

* Drivers may indicate they are to continue receiving events in
USB mode, otherwise they receve nothing until disconnect (they
do receive SYS_USB_DISCONNECTED no matter what).

* Rework a few things to keep the callback implementation sane
and maintainable. ata.c was dreadful with all those bools; make
it a state machine and easier to follow. Remove last_user_activity;
it has no purpose that isn't served by keeping the disk active
through last_disk_activity instead.

* Even-out stack sizes partly because of a lack of a decent place
to define them by driver or SoC or whatever; it doesn't seem too
critical to do that anyway. Many are simply too large while at
least one isn't really adequate. They may be individually
overridden if necessary (figure out where). The thread uses the
greatest size demanded. Newer file code is much more frugal with
stack space. I barely see use crack 50% after idle callbacks
(usually mid-40s). Card insert/eject doesn't demand much.

* No forcing of idle callbacks. If it isn't necessary for one or
more non-disk storage types, it really isn't any more necessary for
disk storage. Besides, it makes the whole thing easier to implement.
