dbab3d2b27 adjust L2 cache flush region to 512k 
although te cache is only 128k, experiments show that the cache
is not reliably flushed until 512k is written. Not sure why...

f4232a3236 stabilize suspend/resume a bit 
- introduce wfi backoff during the suspend process
- increase the region of cache flush - seems to improve
stability
- remove some print calls to avoid interference during
the sleeping process

ebf0a02345 a patch for issue #73 
the problem is that during the computation of the lines, the
cursor isn't wrapping to the next line if the last character
would render "into" the edge of the box. adding a trailing
space to any incoming strings forces the line to wrap.

you can aggravate this condition by typing the following
sentence into the shell:

this is a test of a message that is too long a message

when it fails, it renders

this is a test of a messag
e that is too long a messag

adding the trailing space causes it to render as

this is a test of a messag
e that is too long a messa
ge

which is the desired behavior

387b5d22e5 another fix for issue #75: llio resume failure 
Found the following KP on resume. This time it looks like it's
failing in a syscall, during a send_message call. There's no
more visibility into what causes this, so this commit tries to clean
up some loose ends in the resume path that could send messages before
the system is ready. Namely, the console mux call got condensed into
an abridged version that doesn't send log messages (you couldn't see
them anyways...), and the I2C engine now pauses suspend until
the current transaction at hand completes. I suspect it's quite
likely that it's the I2C engine that's causing the issues...

198ef3d0c8 attempt to address issue #75 
resume failure was seen due to a crash in the engine-25519 process,
in particular, it's crashing on a try_send_message call.
Seems like probably the loader -> kernel transition could have
left some turds in the curve25519 engine, triggering an interrupt
when the system is not yet stable.

this attempts to smooth that over.

5df8275c00 major refactor of the keyboard server 
This one gets rid of a ton of awful, crufty code that was pre-std.
It also removes the following features:

- raw scancode reporting: nobody uses them, and they've never been tested.
They can be added in later if someone wants to e.g. build a MAME emulator.
- multi-listener: there is no good reason to do this on a secure system.
multi-listener is basically a keyboard logger. It's better if we just
control it to a single keyboard listener.

2a77c38a6a minifb: remove fps limiter 
The fps limiter ends up blocking the whole system due to how it limits
the framerate.

If we want to put in a proper rate limiter, we should move the Server
into a different thread and keep just the framebuffer on the main
thread.
