Sean Cross 2f95cc95a4 litex: move more critical code to RAM ... The XIP SPI flash on Fomu is slow, which results in certain operations taking a long time. This becomes a problem for time-critical operations such as USB. Move various calls into RAM to improve performance. This includes the call to __modsi3 and __udivsi3 which are used by the supervisor handler to determine if periodic callbacks need to be run. This finishes fixing #3841 Signed-off-by: Sean Cross <sean@xobs.io>		2020-12-24 14:06:57 +08:00
