reset: fix reset halt bug

I was finally able to figure out the cause of this problem.  There are two
parts to the patch.  The first patch modifies the configuration file I
originally generated for the Atmel AT91SAM9G20 board and achieves the
following:

+++ Splits the reset-init handler into a reset-start handler for some of the
initial configuration activities and keeps the remainder in the reset-init
handler as was the case before.  This was the real issue that was causing
the timing problems I identified before.  This solution was confirmed with
an o-scope on actual target hardware.

+++ Adds a new instruction in the reset-start handler to disable fast memory
accesses in the reset-start handler.  When the target jtag clock is started
out at 2 kHz during system clock initialization, memory writes (i.e.
register write to enable external reset pin -- basically to RSTC_MR) are
naturally slow and cause GDB keep-alive issues (refer to PATCH 2/2 for
additional fixes).

+++ Modifies the configuration file to use srst_only reset action. The
reset-start/reset-init handler split also now allows the correct behavior to
be used in the configuration file (previously had to use both SRST and TRST
even though only SRST is actually used and connected on the evaluation
board).

+++ Adds external NandFlash configuration support to take advantage of flash
driver added earlier.  Doesn't fix any bugs but adds functionality that was
marked as TBD before and thrown in when I did other work on the
configuration file.

xscale: add support for length arg to wp command

This patch adds support for the length argument to the xscale implementation of
the wp command.  Per discussion with David, the length argument specifies the
range of addresses over which a memory access should generate a debug exception.
This patch utilizes the "mask" feature of the xscale debug hardware to implement
the correct functionality of the length argument.  Some limitations imposed by
the hardware are:

   - The length must be a power of two, with a minumum of 4.
   - Two data breakpoint registers are available, allowing for two watchpoints.
     However, if the length of a watchpoint is greater than four, both registers
     are used (the second for a mask value), limiting the number of watchpoints
     to one.

This patch also removes a useless call to xscale_get_reg(dbcon) in
xscale_set_watchpoint() (value had already been read from the register cache,
and the same previously read value is then modified and written back).

I have been using and testing this patch for a couple days.

Questions, corrections, criticisms of course gratefully received.

14 years agoxscale: fix analyze_trace for trace data collected in wrap mode
Mike Dunn [Tue, 13 Apr 2010 17:34:52 +0000 (13:34 -0400)]
xscale: fix analyze_trace for trace data collected in wrap mode

This patch fixes the xscale_analyze_trace() function.  This function was
defective for a trace collected in 'fill' mode (hiccups with repeated
instructions) and completely broken when buffer overflowed in 'wrap' mode.  The
reason for the latter case is that the checkpoint registers were interpreted
incorrectly when two checkpoints are present in the trace (which will be true in
'wrap' mode once the buffer fills).  In this case, checkpoint1 register will
contain the older entry, and checkpoint0 the newer.  The original code assumed
the opposite.  I eventually gave up trying to understand all the logic of the
function, and rewrote it.  I think it's much cleaner and understandable now.  I
have been using and testing this for a few weeks now.  I'm confident it hasn't
regressed in any way.

Also added capability to handle (as best as possible) the case where an
instruction can not be read from the loaded trace image; e.g., partial image.
This was a 'TODO' comment in the original xscale_analyze_trace().

Outside of xcsale_analyze_trace(), these (related) changes were made:

- Remove pc_ok and current_pc elements from struct xscale_trace.  These elements
  and associated logic are useless clutter because the very first entry placed
  in the trace buffer is always an indirect jump to the address at which
  execution resumed.  This type of trace entry includes the literal address in
  the trace buffer, so the initial address of the trace is immediately
  determined from the trace buffer contents and does not need to be recorded
  when trace is enabled.

- Added num_checkpoints to struct xscale_trace_data, which is necessary in order
  to correctly interpret the checkpoint register contents.

- In xscale_read_trace()
  - Fix potential array out-of-bounds condition.
  - Eliminate partial address entries when parsing trace (can occur in wrap mode).
  - Count and record number of checkpoints in trace.

- Added small, inlined utility function xscale_display_instruction() to help
  make the code more concise and clear.

TODO:
 - Save processor state (arm or thumb) in struct xscale_trace when trace is
   enabled so that trace can be analyzed correctly (currently assumes arm mode).
 - Add element to struct xscale_trace that records (when trace is enabled)
   whether vector table is relocated high (to 0xffff0000) or not, so that a
   branch to an exception vector is traced correctly (curently assumes vectors
   at 0x0).
