42e54c508f imx233: workaround hardware dma bug
This bug mostly affects the ZEN and ZEN X-Fi and hangs the lcdif dma randomly
on boot.

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

e671472c3f imx233: fix dma for stmp3600 and stmp3700, improve support
Add finer granularity to start command: now commands can be
prepared, schedule and semaphore increased independently.

246c2127a7 imx233: small dma changes, update debug screen
Reduce DMA maximum transfer size since transfering 64Kb requires
to set a size of 0 and it's not worth adding checks everywhere
to handle this special case. Also add statistics about unaligned
transfer (wrt to cache). Update debug screen accordingly and
simplify it so it can fit smaller screens too.

7d4fed53cc imx233:fuze+: major memory and usb rework
- now identity map dram uncached and have a cached and buffered virtual alias
- rework dma to handle virtual to physical pointers conversion
- fix lcd frame pointer
- implement usb detection properly
- implement bootloader usb properly
- allow the bootloader to disable MMC windowing (useful for recovery)
