cc3200: Use peripheral driver library functions from ROM Previously, CC3200 drivers had two options to use the peripheral driver library APIs: 1) Build driverlib SDK files in Zephyr, in ext/hal/ti/cc3200/* 2) Link directly with the driverlib.a, from an externally installed TI CC3200 SDK. A new option is added to replace option 2), and is now the default: 3) Use the driverlib functions already provided in ROM. This enables a savings in code size, which will depend on the types of device drivers configured and the number of SDK APIs actually used. A rom_report build of the shell sample application showed a savings of about 2kb in code space using this new config option.

# CONFIG_CC3200SDK_BUILTIN can be used for debugging purposes.
# In that case, the CC3200 SDK driverlib must be built with level 0
# optimization (-O0) for the uart module to work properly.
# Note the default build for Zephyr is CONFIG_CC3200SDK_ROM_DRIVERLIB=y
# which uses the ROM versions of the APIs instead.
ext: cc3200sdk: Enable build of CC3200 HAL Enable building CC3200 SDK driver peripheral library files in Zephyr. The SDK provides convenience functions to access CC3200 hardware peripherals, and header files with register definitions.
