tcl/target: add CC2538 and CC26xx target files (with cJTAG procedure) Added support for the Cortex-M3 based TI low power RF SoC CC2538 and the CC26xx family. These chips need a start sequence for switching from cJTAG to JTAG before being used with OpenOCD, this is done in the tcl proc ti_cjtag_to_4pin_jtag in the ti-cjtag.cfg config. The configs for CC2538 and CC26xx run the start sequence on post-reset event and set the ICEPick IDCODE in the data register for OpenOCD to read, this is done so that every time OpenOCD resets the device, it will enable JTAG.

Fix spelling of ARM Cortex It's Cortex-Xn, not Cortex Xn or cortex xn or cortex-xn or CORTEX-Xn or CortexXn. Further it's Cortex-M0+, not M0plus. Cf. http://www.arm.com/products/processors/index.php Consistently write it the official way, so that it stops propagating. Originally spotted in the documentation, it mainly affects code comments but also Atmel SAM3/SAM4/SAMV, NiietCM4 and SiM3x flash driver output. Found via: git grep -i "Cortex " git grep -i "Cortex-" | grep -v "Cortex-" | grep -v ".cpu" git grep -i "CortexM" Change-Id: Ic7b6ca85253e027f6f0f751c628d1a2a391fe914 Signed-off-by: Andreas Färber <afaerber@suse.de> Reviewed-on: http://openocd.zylin.com/3483 Tested-by: jenkins Reviewed-by: Marc Schink <openocd-dev@marcschink.de> Reviewed-by: Andreas Fritiofson <andreas.fritiofson@gmail.com>
