Johny Mattsson	b0f9788a6d	Move constants to ROM. Frees up 16k+ of RAM. ... Accessing 8bit and 16bit constants from ROM rather than RAM comes with a performance cost, as these loads go through the load/store exception vector. Any performance critical constants can be forced back into RAM as RAM_CONST_ATTR. The entry point has changed from call_user_start() to user_start_trampoline() in order for the exception handler to be installed early enough.	2015-06-23 15:41:14 +10:00
