[PATCH 1/3] char: hw_random: Add Amlogic Meson Hardware Random Generator

[LABBE Corentin]

Hello

I have some minor comments below

> +config HW_RANDOM_MESON

> +	depends on HW_RANDOM && ARCH_MESON

Perhaps you could change to:
depends on HW_RANDOM
depends on ARCH_MESON || COMPILE_TEST

I think you need a test for max < sizeof(u32)
