Squashed commit of the following: confgs/launchxl-cc1310: Add board support for the LaunchXL-CC1310. This is a work in progress and does not yet build error free. arch/arm/src/tiva/cc13xx: cc13x0_trim.c now compiles; Make xxx_rom.h header files conform a little more closely to the NuttX coding style. arch/arm/src/tiva/cc13xx: CC13x2 (V1 and V2) rom.c files now build with no errors or warnings. Still have to work through the CC13x0 version. arch/arm/src/tiva/hardware: Add CC13x0/CC13x2_CC26x2 AON BATMON register definition header file. arch/arm/src/tiva/cc13xx: A little more progress converting TI DriverLib ROM code to NuttX coding style. Lots of possibilities for breakage here! arch/arm/src/tiva/cc13xx: Remove functions from cc13x._rom.c that are defined from ROM access in cc13x._rom.h; Add prototypes in cc13x._rom.h for functions in cc13x._rom.c that are not defined in cc13x._rom.h. arch/arm/src/tiva/cc13xx: Remove some dangling whitespace at the end of lines. arch/arm/src/tiva/cc13xx: Second (and final) round of name changes to get ROM function-like defines consistent with NuttX coding standard arch/arm/src/tiva/cc13xx: Fix a few errors in last big name conversion. arch/arm/src/tiva/cc13xx: First round of name changes to get ROM function-like defines consistent with NuttX coding standard arch/arm/src/tiva/cc13xx: Remove ROM_ prefix from function-like defines.
