Instead of having to enable ramfunc support manually, just make it transparently available to users, keeping the MPU region disabled if not used to not waste a MPU region. This however wastes 24 bytes of code area when the MPU is disabled and 48 bytes when it is enabled, and probably a dozen of CPU cycles during boot. I believe it is something acceptable. Note that when XIP is used, code is already in RAM, so the __ramfunc keyword does nothing, but does not generate an error. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> |
