[Openocd-svn] r2134 - in trunk/tcl: board target

[<zw...@ma...>]

New Revision: 2134

Added:
   trunk/tcl/board/csb337.cfg
Modified:
   trunk/tcl/target/str912.cfg
Log:
David Brownell <da...@pa...>:

Add configuration for an old AT91rm9200 board, the Cogent CSB 337.
Worth noting from the OpenOCD perspective:

 - It got a real hardware trace port connector; wired up here as
   much as we can, lacking inexpensive trace-aware dongles.

 - This is the first in-tree use of the "arm920t cp15" command.
   It adjusts the CPU clocking and enables i-cache, which gives
   more than 4x speedup after booting Linux; it's visible even
   just running U-Boot.

Factor interface list to its own command:
- Add handle_interface_list_command, used by handle_interface_command.
- Display output of new list to command console.

New Revision: 2128

Modified:
   trunk/src/jtag/jtag.c
Log:
Cleanup and simplify handle_interface_command:
- Reduce indent: invert logic of strcmp test.
- Reduce scope: declare variables upon first use in loops.
- Reduce unsaid: compare end of table with NULL.
- Remove superfluous braces around blocks with one statment.
- Improve language that introduces the list of built-in drivers.
