Voltage can be read using as3543 adc (i.e. ascodec api, on this target implemented
via ioctl()). TODO: Look into possibly controlling charging more by re-using
powermgmt-ascodec.c. However, charging seems to be controlled by the kernel,
so may not be needed.
Charger state can be read using /dev/minivet. It allows to differentiate between
wall charger and usb charging, but that's not implemented (is it even worthwhile?)

This commit changes the default HDD endianness to the correct one,
but stays compatible with the old endianness.
If an MBR with the wrong endianness is detected, it will
automatically enable word swapping and issue a warning splash.
To permanently fix this you'll need to upgrade emCORE to at least r836.
This will wipe all data! A post-r836 build of emCORE will be
officially released during the next couple of days.

DEBUG_GIO allows users to set any GIO options (direction, output state). As this feature should be used only by experienced users it is compiled conditionally.
Raise I2C delay values since udelay() is now precise and previous values seems to be too low for some devices.

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

The new menu is very helpful on RaaA, but also shown in the sim. It shows
the process cpu usage, process' time stats (user,sys,real) and the cpu
frequency stats.
It uses a thread to sample the data, however the thread is not created
until the menu is visited for the first time.

Nick some aspects from the as3525 ascodec driver to improve throughput in
the beast's SPI communications by switching tranfer descriptors to the
caller's stack and getting rid of thread synchronization.
Fix a bug that suddenly became obvious that could permanently stall the SPI
driver because all data could be shifted out before the interrupt could get
serviced. In that case, it needs a kick to restart it. Should probably put
the SPI interrupt priority above DVFS.
A tweak to the event registration interface to simplify it.

Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections,
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.

When a global pointer is not declared as constant, gcc will put it in
memory. Getting the address of the string it points to requires loading
the address of the pointer and then loading the pointer. When the pointer
is declared constant, the address of the string is loaded directly.

* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
so that -ffunction-sections works for those asm file too.

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).
