Enables rtic-monotonic

Affects timer::monotonic…

i2c-write-iter

Implement i2c-write-iter traits

Enables i2c-write-iter

dcp-fast-f64

Use DCP to accelerate some (but not all) f64 operations.

If you really want to save every last micro-amp, and know you aren't doing any f64 operations, you can disable this feature (which is on by default) and then manually disable the DCP by either clearing the bits we set for you in the CPACR register, or changing the #[entry] macro to not set those bits.

Almost everyone will want this on, but we let the BSPs make that choice.

binary-info = rt

Add a binary-info header block containing picotool-compatible metadata.

Requires 'rt' so that the vector table is correctly sized and therefore the header is within reach of picotool.

Enables binary-info of rp-binary-info
