Qeditor has been improved in many ways:
- it can now dump all registers, just like the lua DUMPER.dump_all() command
- several crash were fixed
- when connected to a hwstub command, one can correctly edit individual fields
- the code was simplified in several places

The graphical editor can now display and editor description files.
The library has been improved to provide more useful function.
The XML format has been slightly changed: only one soc is allowed per file
(this is was already de facto the case since <soc> was the root tag).
Also introduce a DTD to validate the files.

- drop support for PP500x: it's very different from other PP and although
it would be possible to support them, I don't have one to test the code
- make sure only the CPU is started
- add PP descriptor to report chip ID and revision
- add code in shell and lua to support pp (no register description yet)
- compile for ARMv4 because PP502x is an ARM7TDMI

It is very similar to how e200tool from MrH works but uses the framework
of hwstub which is makes it completely trivial since we already have the
USB driver written.

This is actually the trivial part of e200tool from MrH: it simply writes the
code on the bulk endpoint. Code was mostly copied from imxtools/sbloader.

On some OSes like Windows or if running in a virtual machine, the one second
timeout might be too short.

The UI now has a "read-only" check box to prevent accidently changes: once
unchecked, the UI can do write to register (only full register writes are
supported for now). If the register supports it, the UI provides SCT writes
as well. The display register panel was moved to its own class to cleanup
things a bit.

The code was a mess with respect to soc handling: some code just plain copied
the SoC descriptor which are big objects, some was using indexes. The new soc
factor out everything in a few classes which hide these ugly details so that
descriptors are never copied.

A SoC descriptor is not a small object: it can be as large as ~100KiB so
it's better to avoid copying things over.

This commit add the very handy feature of being able to read registers
directly from a device using hwstub. This is mostly trivial using the hwstub
library and the biggest change here is actually:
- being able to read registers by name and/or addresses
- being able to enumerate devives
The UI code currently doesn't handle hotplug but the backend does so it should
be trivial to add in the future. It also opens up the possibility the write
registers from hwstub or save the register values to a file.
Since it relies on both hwstub and libusb, a switch has been introduced in
qmake to disable it (use -config nohwstub).

In might be useful to load hwstub in an environment with the MMU active,
in which case care must be taken on the order in which things are done.
Mostly, one should not disable the MMU before moving stuff around. The code
assumes the linking address (0 currently) is identity mapped.

The protocol has evolved a lot during the 2.x.y lifetime, bringing more
features which later got unused. This commit removes all the unused stuff
and simplifies everything:
- drop the feature mask: everything is mandatory or stalled on error
- remove the info request and put all static information in standard USB
descriptors which are part of the configuration descriptor (and can be
retrieved using the standard GetDescriptor request).
- remove the USB interface, we had only one anyway
- remove all endpoint descriptors
- remove the exit/atexit stuff, it never worked as intended anyway
- update the hwstub library and make it able to handle any device
- update the tools (mostly renaming and removing of code)

This test software setups timer T0 periodic interrupt.
In ISR it changes backlight level. The interrupt handler
does not support nesting and the whole ISR is run in interrupt
context. Exceptions are not handled yet.

This is the basic port to the new target Samsung
YP-R1, which runs on a similar platform as YP-R0.
Port is usable, although there are still
some optimizations that have to be done.

The getty service mointors /dev/ttyGS0 (also created by the patched firmware).
When the g_serial.ko module is loaded this automatically enables shell access
via usb. It exposes a cdc-acm device to the host which is compatible to linux
(usb_serial.ko) and windows.
The g_serial.ko is not included module can be build from the YP-R0 open source
package provided by samsung. It can be loaded via rc.user on the internal memory.

This simple program shows how to setup timer for periodic
operation. Interrupts are not used yet and simply pending
irq bit is polled and cleared when set. This program
supports my understanding of disassm of ADEC_N63.BIN that
P_CLK is configured for 7.5MHz and timer clock source is P_CLK
directly.
