hwstub: port hwstub_shell to the new library

2016-04-08T17:38:18+00:00

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)

hwstub/qeditor: add support for atomic read/writes

2014-11-18T22:30:44+00:00

The current code assumed that READ/WRITE would produce atomic read/writes for
8/16/32-bit words, which in turned put assumption on the memcpy function.
Since some memcpy implementation do not always guarantee such strong assumption,
introduce two new operation READ/WRITE_ATOMIC which provide the necessary
tools to do correct read and write to register in a single memory access.

hwstub: don't put revision in the protocol, it's specific to the implementation

utils/hwstub: completely rework the protocol, drop unused features

2014-02-10T22:14:24+00:00

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)

hwstub: major improvement in the stub and the tools

2013-06-13T00:25:15+00:00

Fix the stub in many way to correctly detect the STMP family and
act upon that. Drop some unused commands and bump version.
Rewrite the tool to allows scripting in lua and load the register
description from an XML file using the regtools. Introduce a new
tool to load and run code using the hwstub (either binary format
or Rockbox additive scramble format). Also switch to an optimise
version of the memcpy/move/set functions to correctly handle
alignement issue (like writing a full word/half-word when
possible for registers which is crucial)
