7e00be9a1e nwz-370/380: increase adc button error margin
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.

9fe854e782 imx233: enhance button driver adc handling
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.

030a9da0d7 imx233: cosmetics
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.

f182e2df66 imx233: make sure not to discharge battery when charge is complete
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.

eac1ca22bd imx233: generate register headers using headergen_v2 and update code for it
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

f6ed4f8306 iPod Classic: use PMU interrupts to detect accessories
- 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.

94b23da3c4 Sansa Connect: change bootloader linker file
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.

e62203aac1 regtools: add headergen_v2
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.

52a6db3a36 iPod Classic: optimize UDMA timming for ATA drives
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:

             UDMA 0      UDMA 1      UDMA 2      UDMA 3      UDMA 4
 tACKENV     (20, 70)    (20, 70)    (20, 70)    (20, 55)    (20, 55)
 tRP         (160, --)   (125, --)   (100, --)   (100, --)   (100, --)
 tSS         (50, --)    (50, --)    (50, --)    (50, --)    (50, --)
 tDVS        (70, --)    (48, --)    (31, --)    (20, --)    (6.7, --)
 tDVH        (6.2, --)   (6.2, --)   (6.2, --)   (6.2, --)   (6.2, --)
 tDVS+tDVH   (120, --)   (80, --)    (60, --)    (45, --)    (30, --)

 Tcyc = tDVS+tDVH
 WR[bytes/s] = 1/Tcyc[s] * 2[bytes]

On Classic (boosted):
 HClk = 108 MHz. -> T = ~9.26 ns.

Old values (used by OF):
 UDMA  ATA_UDMA_TIME  tACK  tRP    tSS   tDVS  tDVH  Tcyc   WR(MB/s)
 0     0x5071152      27.8  166.7  55.6  74.1  55.6  129.7  15.4

New values:
 UDMA  ATA_UDMA_TIME  tACK  tRP    tSS   tDVS  tDVH  Tcyc   WR(MB/s)
 0     0x4071152      27.8  166.7  55.6  74.1  46.3  120.4  16.6
 1     0x2050d52      27.8  129.6  55.6  55.6  27.8   83.4  24
 2     0x2030a52      27.8  101.8  55.6  37    27.8   64.8  30.9

 4     0x1010a52      27.8  101.8  55.6  18.5  18.5   37    54

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.

469d645390 iPod Classic: prepare i2c and PMU for bootloader
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.

c90d42dcc6 jz4670_tools: add usbboot tool, tweak Makefile and packtool
Although the jz4740 contains a similar tool to usbboot, its command-line
interface is not very useful, also it does not compile by default because it
relies on some external code, and it contains code specific to some JZ4740
devices.

5ac0166388 qeditor: port to the new hwstub library and add features
This commit adds support for the version of the hwstub library, which requires
a lot of changes. It also adds some editing features, such as register access
and much better editing of fields using the mouse (double click on a field
to be able to resize and move it).

cc4c9b70bc regtools: add register access to soc desc
Registers (and variants) can now specify the type of access supported:
- unspecified: for variant means same as register, for register defaults R/W
- read/write
- read only
- write only
Backward compatibility is preserved by setting access to unspecified by default.

f6c61eb11a hwstub: port hwstub_shell to the new library
Also use this opportunity to cleanup support for multiple devices: the shell
now supports dynamic changes in the device and will call init() everytime
a new device is selected, to prepare a new environment. The shell now
honors register width on register read/write. The shell also provides access
to variants as follows by creating a subtable under the register using the
variant type in UPPER case and having the same layout as a register.
For example if register HW.GPIO.DIR has variants "set" and "clr", those can
be used like this:
HW.GPIO.DIR.SET.write(0xff)
HW.GPIO.DIR.CLR.write(0xff00)
