flash Kinetis: new KVx family added
Cortex-M0+ and M4 motor control MCUs KV10, KV11, KV30, KV31, KV42, KV44 and KV46 added to SDID identification. Watchdog disable code changed to work on Cortex-M0+ (KV1x) Protection size set to 1K for 16K flash devices (KV10Z16) - cherry picked from Andrey Smirnov's change #2051 Change-Id: Ia6f4868eaf7e2cb6ad6a736210c703a67e0027be Signed-off-by: Tomas Vanek <vanekt@fbl.cz> Reviewed-on: http://openocd.zylin.com/3235 Tested-by: jenkins Reviewed-by: Kyle Manna <kyle.manna@fuel7.com> Reviewed-by: Freddie Chopin <freddie.chopin@gmail.com>__archive__
