* trng: Rename rand to trng_randTom Hughes2022-07-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | The declaration for rand conflicts with the standard library declaration so rename it from "rand" to "trng_rand". This has the benefit of making it obvious when we're using the true random number generator. For consistency, this also renames init_trng/exit_trng to trng_init/trng_exit. This is a reland of commit a6b0b3554f59cc9b0c4aae9bff7dff075f2089a9.

* chip/host: Add check for TEST_BUILD in trng.cCraig Hesling2019-07-271-0/+4
| | | | | | | | | | | | | | | | | | | Due to the possibly unnoticeable security vulnerability it would cause if the dummy host trng driver made it's way into production (non-test) code, this change adds a small check to ensure it is being used only in test or fuzz builds. This isn't as much of a concern for other dummy host drivers. For example, including a fake spi driver may simply manifest as broken feature.

This adds fake SPI Master and TRNG support to the host target. This change also adds the missing emulated gpio interface function. Although general purpose, these changes are setup for allowing fuzzing of the FPMCU specific host commands. Thus, they do not impact any outstanding code.
