2012-05-07cfg: add default pid/vid pair to beaglebone board cfg.Bill Traynor
The newer versions of BeagleBone boards use the default vid/pid pair for FT2232 debugging. Please see the following README: http://beagleboard.org/static/beaglebone/latest/README.htm On revision A3/A4 boards, the VID/PID were chosen to match the TI XDS100v2 (0x0403/0xA6D0). On A5 and newer revisions when we've given the authors of CCS the chance to update their software, the generic FTDI VID/PID (0x0403/0x6010) will be used to simplify installation of drivers for systems already having those drivers.

2012-04-26topic: Added support for the SAM4S variantsOlivier Schonken
Atmel introduced 6 new Cortex-M4 processors on 2011-10-26 SAM4S16C - 1024KB flash LQFP100/BGA100 SAM4S16B - 1024KB flash LQFP64/QFN64 SAM4S16A - 1024KB flash LQFP48/QFN48 SAM4S8C - 512KB flash LQFP100/BGA100 SAM4S8B - 512KB flash LQFP64/QFN64 SAM4S8A - 512KB flash LQFP48/QFN48 The SAM4S processors still suffer from the "6 waitstates needed to program device" errata. Other relevant changes are: 1. Address of flash memory starts at 0x400000. 2. EWP (Erase page and write page) only works for the first two 8KB "sectors" 3. Because of the EWP not working for all the sectors, normal page writes have to be used. The default_flash_blank_check is used to check if lockregions should be erased. 4. The EA (Erase All) command takes 7.3s to complete. (Previous timeout was 500 ms) 5. There are 128 lockable regions of 8KB each. Implemented default blank checking, and page erase for load_image scenarios. This is to compensate for the EWP flash commands only working on the first 2 8KB sectors.

2011-10-30config files: Drop incorrect comments.Uwe Hermann
There are many "force an error till we get a good number" comments in target/board files. This refers to the use-case where a config script sets _CPUTAPID to 0xffffffff (which presumely gets overridden later): if { [info exists CPUTAPID ] } { set _CPUTAPID $CPUTAPID } else { # Force an error until we get a good number. set _CPUTAPID 0xffffffff } However, the same comment was also copy-pasted in many files which do _not_ set _CPUTAPID to 0xffffffff, where the comment doesn't make any sense at all. Drop those comments. Also, add one missing comment, and fix small whitespace and grammar issues.
