Re: [PATCH v2 2/2] PRU: Align libmath to PRU ABI

[Dimitar Dimitrov <dimitar at dinux dot eu>]

There is no particular reason. I saw that it is being used by many libm sources. I'm willing to

What is the preferred newlib license? https://spdx.org/licenses/BSD-2-Clause.html or https://
spdx.org/licenses/BSD-2-Clause-FreeBSD.html ?

Thanks,
Dimitar
