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

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.
