Mike Dunn [Sat, 20 Mar 2010 14:53:47 +0000 (10:53 -0400)]
fix software breakpoints on xscale

This patch fixes xscale software breakpoints by cleaning the dcache and
invalidating the icache after the bkpt instruction is inserted or removed.  The
icache operation is necessary in order to flush the fetch buffers, even if the
icache is disabled (see section 4.2.7 of the xscale core developer's manual).
The dcache is presumed to be enabled; no harm done if not.  The dcache is also
invalidated after cleaning in order to safeguard against a future load of
invalid data, in the event that cache_clean_address points to memory that is
valid and in use.

Also corrected a confusing typo I noticed in a comment.

TODO (or not TODO...?): the xscale's 2K "mini dcache" is not cleaned.  This
cache is not used unless the 'X' bit in the page table entry is set.  This is a
proprietary xscale extension to the ARM architecture.  If a target's OS or
executive makes use of this for memory regions holding code, the breakpoint
problem will persist.  Flushing the mini dcache requires that 2K of valid
cacheable memory (mapped with 'X' bit set) be designated by the user for this
purpose.  The debug handler that gets downloaded to the target will also need to
be extended.

David Brownell [Mon, 22 Mar 2010 05:49:23 +0000 (22:49 -0700)]
ft2232 init mess cleanup

In the ft2232 driver, initialization for many layouts punts to a routine
called usbjtag_init(), instead of a routine specific to each layout.

That routine is  a mess  built around a "what type layout am I" core.
That's a bad design ... in this case, especially so, since it bypasses
the layout-specific dispatch which was just done, and obfuscates the
initialization which is at least somewhat generic, instead of being
specific to the "usbjtag" layout.

Split and document out the generic parts of usbjtag_init(), and make
the rest of those layouts have layout-specific init methods.  Also,
rename usbjtag_reset() ... that also was not specific to the "usbjtag"
layout, and thus contributed to the previous code structure confusion.

(Eventually, all layout-specific code (and method tables) should probably
live in files specific to each layout.  These changes will facilitate
those and other cleanups to this driver.)

Basic functionality can be selected with command:
     lpc3180 select 0 slc

David Brownell [Wed, 3 Mar 2010 06:41:59 +0000 (22:41 -0800)]
ARM: start abstracting ADIv5 transports (JTAG/SWD)

To support both JTAG and SWD, ADIv5 needs DAP operations which are
transport-neutral, instead being of JTAG-specific.  This patch:

 - Defines such a transport-neutral interface, abstracting access
   to DP and AP registers through a conceptual queue of operations.

 - Builds the first implementation of such a transport with the existing
   JTAG-specific code.

In contrast to the current JTAG-only interface, the interface adds
support for two previously-missing (and unused) DAP operations:

 - aborting the current AP transaction (untested);
 - reading the IDCODE register (tested) ... required for SWD init.

The choice of transports may be fixed at the chip, board, or JTAG/SWD
adapter level.  Or if all the relevant hardware supports both transport
options, the choice may be made at runtime, This patch provides basic
infrastructure to support whichever choice is made.

The current "JTAG-only" transport choice policy will necessarily continue
for now, until SWD support becomes available in OpenOCD.  Later patches
start phasing out JTAG-specific calls in favor of transport-neutral calls.

LPC1768 updates, IAR board support

Fix some issues with the generic LPC1768 config file:

 - Handle the post-reset clock config:  4 MHz internal RC, no PLL.
   This affects flash and JTAG clocking.

 - Remove JTAG adapter config; they don't all support trst_and_srst

 - Remove the rest of the bogus "reset-init" event handler.

 - Allow explicit CCLK configuration, instead of assuming 12 MHz;
   some boards will use 100 Mhz (or the post-reset 4 MHz).

 - Simplify: rely on defaults for endianness and IR-Capture value

 - Update some comments too

Build on those fixes to make a trivial config for the IAR LPC1768
kickstart board (by Olimex) start working.

Also, add doxygen to the lpc2000 flash driver, primarily to note a
configuration problem with driver: it wrongly assumes the core clock
rate never changes.  Configs that are safe for updating flash after

after switching to use PLL0 at 100 MHz.
