Map short menu press to context menu/quickscreen.
Map long menu press to return to main menu.
Also remove some stupid keylock mapping, that doesn't make sense.

Always enable support for SET_BLOCK_COUNT on mmc: it is mandatory. For some
reason (probably a mistake) it was disabled unconditionaly on mmc.
Also deselect sd card after init. Although it is unlikely to make a difference,
it is already done for mmc so stay consistent.

The screen currently displays for each device the bus width, set_block_count

Some players like the ZEN X-Fi have a wide but not tall screen, it is
thus better to display everything on one line for each button

ffmpeg_bitstream.c is included in libcodec, so there doesn't seem to
be any reason for individual codecs to also compile it (and clobber
any previous copy while they're at it, leading to broken builds)

This screen allows to put the device in a special mode where:
- charging is disabled
- device only draws power from 5V (thus battery is untouched)
This is useful to measure the device consumption by measuring directly
the usb power consumption.

Per Freescale recommandation, we need to ramp up the 4.2V rail before enabling
charging. Ramping should be done at 1 step/10ms, but the old code did 1 step/1s
because the powermgmt_step() function is called once every second. Use a tick
task to ramp up much faster.

The old code used button_get() to read the button status and wait for a
key to leave the panic screen. This is broken since when IRQ are disable,
the button mask is not updated anymore for touchpad and adc buttons. For
now, only use pswitch: this should be good enough for all targets.

The old timrot setup API was very low-level and unfriendly. The new one
makes in easier to select the frequency source. Use to simplify timer
and kernel timer code.

The adc channel monitored for jack detection does not really have a fixed
value when plugged. Instead use the same logic as the OF and simply use a
threshold.

For some reason those targets have quite imprecise button voltages and the
old margin was too small. This should fix the button-not-working issue,
especially when the player is very hot and cold.

The current driver is limited to checking if the adc value equals another
one with a hardcoded margin. This commit changes two aspects of that:
- the margin can be changed globally using IMX233_BUTTON_LRADC_MARGIN
and can also be overriden per button using the new LRADC_EX macro
- the lradc logic gained two comparison modes to check if the source
value is greater (or lower) than a threshold.

Shorten some text to make the text readable in the debug screen of
targets with small LCD (like NWZ-380). In some screens, the only
option is to display less information.

The power management code was erroneously shuting down the 4.2V rail
when charging is complete. This resulted in the DCDC draining the battery
and thus the battery discharging with USB plugged...
The new code keeps the 4.2V rail active so that battery remains untouched
once charge is complete.

NOTE: this commit does not introduce any change, ideally even the binary should
be almost the same. I checked the disassembly by hand and there are only a few
differences here and there, mostly the compiler decides to compile very close
expressions slightly differently. I tried to run the new code on several targets
to make sure and saw no difference.
The major syntax changes of the new headers are as follows:
- BF_{WR,SET,CLR} are now superpowerful and allows to set several fileds at once:
BF_WR(reg, field1(value1), field2(value2), ...)
- BF_CS (use like BF_WR) does a write to reg_CLR and then reg_SET instead of RMW
- there is no more need for macros like BF_{WR_,SET,CLR}_V, since one can simply
BF_WR with field_V(name)
- the old BF_SETV macro has no trivial equivalent and is replaced with its
its equivalent for BF_WR(reg_SET, ...)
I also rename the register headers: "regs/regs-x.h" -> "regs/x.h" to avoid the
redundant "regs".
Final note: the registers were generated using the following command:
./headergen_v2 -g imx -o ../../firmware/target/arm/imx233/regs/ desc/regs-stmp3{600,700,780}.xml

- Speed auto detection is launched when an accessory is inserted,
so the user doesn't need to modify settings to use accessories
that operates at different speeds (or when the same accessory is
unplugged and plugged again).
- UART controller is disabled when no accessory is inserted, not
much powersave but everything counts.

Since the stub code is shared with NWZ-360, it enables the pullup for the
hold button, but the NWZ-370/380 doesn't have a hold button so don't compile
this code in, it could potentially have unexpected effets or increase consumption

This change ensures that Sansa Connect bootloader.bin will fit in its flash
partition.
Fix _flash_sizem calculation, division was not working properly because
FLASHSIZE included subtraction and defined value was not in parenthesis.
Prior to this change _flash_sizem was 0x00800000, now it is correctly set
to 4 in case of Sansa Connect and 8 in case of other TMS320DM320 players.
This significantly improves boot time as cache is now enabled only for
real flash memory region.

PMU interrupts are used to detect USB Vbus, wall adaptor, accessories
and holdswitch. A thread is needed to poll the PMU throught I2C, ATM
it does nothing but showing the state of the inputs on the HW debug
menu, funcionallity for each individual input will be added in next
patches.

When the bootloader starts, most of HW never has been initialized.
This patch includes all code needed to perform the preliminary
initialization on SYSCON, GPIO, i2c, and MIU.
The code is based on emCORE and OF reverse engineering, ported to

This new header generator works differently from the previous one:
- it uses the new format
- the generated macro follow a different style (see below)
- the generated macro are highly documented!
- it supports SCT-style platform or RMW-style ones
Compared to the old style, the new one generate a big set of macros per
register/field/enum (loosely related to iohw.h from Embedded C spec). The user
then calls generic (names are customizable) macros to perform operations:
reg_read(REG_A)
reg_read(REG_B(3))
reg_read_field(REG_A, FIELD_X)
reg_read_field(REG_B(3), COOL_FIELD)
reg_write(REG_A, 0x42)
reg_write_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_write_fielc(REG_B(3), COOL_FIELD_V(I_AM_COOL), BLA(42))
the following use RMW or SET/CLR variants, depending on target:
reg_set_field(REG_A, FLAG_U, FLAG_V)
reg_clr_field(REG_A, FIELD_X, FIELD_Y, IRQ)
reg_clr_field(REG_B(3), COOL_FIELD, BLA)
the following does clear followed by set, on SET/CLR targets:
reg_cs(REG_A, 0xff, 0x42)
reg_cs(REG_B(3), 0xaa, 0x55)
reg_cs_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_cs_field(REG_B(3), COOL_FIELD_V(I_AM_COOL))
The generator code is pretty long but has lots of documentation and lots of
macro names can be customized.

The write buffer size is undefined to use the default 24Kb. size
defined (and recomended) in usb_storage.c, the read buffer size is
also decremented to 24 Kb. USB sequential read and write benchmarks
using diskdump are now 8-9% faster.

This patch optimizes UDMA timings to increase write transfer rate on
ATA bus, these transfers are clocked by HCLK, tDVS+tDVH is modified to
decrease Tcyctyp (typical write cycle period). This is not overclocking,
we meet the ATA standar, the settings used by OF are not well optimized
for each UDMA mode, we will never know but probably this was due some
documentation issue.
ATA_UDMA_TIME register is documented on s3c6400 datasheet, information
included in s5l8700 datasheet is wrong or not valid for s5l8702.
From ATA specs, (Minimum, Maximum) values in nanoseconds:

To verify that the settings are correct, a write-to-cache test was
performed using emCORE, the measured transfer rate (WRm) is compared
against the theoric transfer rate (WR) at 108 Mhz for the old and
the new UDMA4 settings (iPod 160, HDD Toshiba MK1634GAL):
UDMA ATA_UDMA_TIME Tcyc(ns) WR(MB/s) WRm(MB/s) RDm(MB/s)
4 0x2010a52 46.3 43.2 42.9 59.8
4 0x1010a52 37 54 53.5 59.8
Notes:
- The new UDMA4 settings increases ~25% the ATA transfer rate for
cached-writes. The real HDD write speed is limited by the internal
transfer rate (depends on cilinder, for the MK1634GAL it is 276 to
573 Mbits/s). Sequential write benchmark using diskdump on USB are
~8% faster.
- Read transfers are clocked by the device, it depends on UDMA mode
selected and are not affected by HClk or ATA_UDMA_TIME settings.
Read-from-cache tests results (RDm) using HClk=108 and HClk=54 for
UDMA4 are 59.8 MB/s on MK1634GAL.
- Minimum HClk is limited by tACKENV specs, using current settings
it is 54 MHz for UDMA4,UDMA3 and 43 MHz for UDMA2,UDMA1,UDMA0.

When the bootloader starts only IRAM is available, the first task is to
ask the PMU to verify if the iPod has previously been hibernated by OF.
Due to memory limitations, the kernel cannot be used on this stage.
This patch modifies I2C and PMU low level functions to not to depend
on kernel (removes mutexes, and uses HW timer instead of current_tick),
actual kernel functions are modified to be 'mutexed' wrappers of the new
functions.

The kernel on this device reports nonexistent key presses, in particular it
reports right presses when pressing the left button... Since when it happens,
the right press comes after the left one, the new code simply ignores any
right press when the left button in pressed.
