cortex_a: fix endiannes issues on  TI TMS570

at91smad: Fixes to 'samd_protect'

Some fixes to 'samd_protect' including:
     - Fix a bug in which the value of 'set' parameter passed into the
     function was ignored so it was impossible to remove flash
     protection once it was set.
     - Check the protection status of the sector via 'is_protected'
     field of the  corresponding 'flash_sector' structure to see if
     any actual HW manipulations needs to be done.
     - Change the way the errors during protection activation are
     handled. Now even in the case of error in the middle of
     protecting a number of sectors the subroutine would still update
     the state of the sector protection in sectors array so as to
     avoid cases where openocd thinks that the sector is not protected
     while it actually is.

tcl: introduce init_target_events and use it for gdb flashing events

This introduces a new global Tcl procedure that is run just after
init_targets and before init_boards.

Its default behaviour is to assign gdb-flash-erase-start and
gdb-flash-write-end to reasonable defaults.

The rationale for doing "reset init" before gdb erases and flashes
memory is that all flash drivers are written in assumption that they
can safely be used only after chip reset (plus chip-specific
configuration in the init handler if any). The need to use "reset
halt" after flashing is because a user expects running firmware after
loading to be the same as running it from power-on-reset.

jlink: add support for Jlink-OB (0x0105) devices

The JLink-OB (onboard) devices work the same way as the normal JLink
except that their PID is 0x0105 (and that's the only one we know of so
far) and their endpoint addresses are different due to there being a
CDC-ACM interface as well.  These JLink-OB devices show up on a lot of
vendors' development kits as an integrated debugger.

This change simply checks whether the adapter we opened has a JLink-OB
PID and, if it does, uses the JLink-OB endpoints rather than the
default.  To do this, we add a new routine, jtag_libusb_get_pid() to the
libusb adapter layer, it in turn just calls
libusb_get_device_descriptor(), which previously had no wrapper.

Also, checkpatch.pl doesn't like the VID/PID macros as defined so I
moved them to the array itself.  This should have no effect on the code.

This change adds the 0102 through 0104 PIDs to openocd.rules as well as this
new 0105 PID.

Tested on an Atmel SAM4S Xplained board which has a JLink-OB, also

Make the Atmel SAM3 family SWD-aware

Atmel's SAM3 and SAM4 processor families are very close to each other
in many respects.  However, so far, only the SAM4 target script
contained the magic to allow using SWD, while SAM3 was tied to JTAG
only.  This e.g. prevented the CMSIS-DAP driver from accessing SAM3
devices as it only uses SWD transport (by now).

The patch pulls all the things from the SAM4 target script that are
also applicable to SAM3 devices.  With the patch, an Atmel CMSIS-DAP
debugger (Atmel-ICE) was proven to be able to successfully attach to a
SAM3S-EK evaluation kit.  I also cross-checked that accessing through
a SAM-ICE (Segger J-Link) still works with the patch.

All Atmel-provided CMSIS-DAP devices use 512 byte packet size

The existing CMSIS-DAP driver matches the USB VID/PID against 0x3eb
(Atmel VID) and 0x2111 (Atmel EDBG embedded CMSIS-DAP debugger), and
then bumps the packet size from its default of 64 to 512.  However, it
turned out that *all* Atmel-provided CMSIS-DAP devices (EDBG with PID
0x2111; JTAGICE3 with firmware version 3.x, PID 0x2140; new Atmel-ICE
[successor of JTAGICE3], PID 0x2141) require a 512-byte packet size.
Obviously, all run the same USB implementation inside their custom
microcontroller.  Thus, it seems best to simply assume that *all*
Atmel CMSIS-DAP devices use this packet size, and don't check the PID
at all.

The XDS100v2 is often embedded in a number of platforms using the
VID/PID of 0x0403/0x6010 and a generic FTDI device description.  Add

stlink: Use callback to increase frequency of trace data sampling

The ST-LINK/V2 has limited internal buffering, such that trace data
can be missed if the target is generating data at a rate quicker than
the OpenOCD trace sampling. The issue of lost data is compounded since
individual TPIU packets may be split across individual STLINK_TRACE_EP
reads, and misleading results can occur if mid-packet loss occurs.

This patch increases the frequency of checking for pending trace data
with the aim of minimising such losses. Note: With the limited (I/O
and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a
guarantee against trace data loss.

The timer callback is only added when enabling tracing, and is removed
when tracing is disabled.
