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.

topic: Added support for the SAM4S variants 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.
