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.
