This allows other systems to see what baud rate the host has requested.

altos/lpc: Really fix aes entry in lpc vpath2017-04-22T04:32:26+00:00Keith Packardkeithp@keithp.com2017-04-22T04:32:26+00:00urn:sha1:5849ee6c09669e6d2e6940a76bcb5cc23178fc68
I added another entry instead of fixing the existing one. Not ideal.

altos/lpc,altos/stmf0: Use -n flag to work around link editor issue2017-04-22T00:06:23+00:00Keith Packardkeithp@keithp.com2017-04-22T00:06:23+00:00urn:sha1:64ac93f5495db7a8b06f1eb4fe4eb2418125d792
Something changed in the link editor which makes it complain about 'no
space for program headers' on LPC and STMF0 builds. Somehow, adding
the '-n' flag to the linking step fixes it. It doesn't appear to break
the build, so I guess it's ok?

altos/lpc: Add (void *) cast to fix alignment warning2017-04-21T23:40:58+00:00Keith Packardkeithp@keithp.com2017-04-21T23:40:58+00:00urn:sha1:adb842b64b04a7d70e543bad7ae59807d549e85a
The -Wcast-align warning is generated when this cast is not present.

vpath reference to aes was busted.
WARN_CFLAGS needs -Wcast-align.
Wrap AO_CFLAGS.

altos/lpc: Handle USB reset by resetting internal state2016-06-10T21:33:50+00:00Keith Packardkeithp@keithp.com2016-06-10T21:33:50+00:00urn:sha1:54f8d53584d0a902676b441cd122c01cd54f2283
Just like stmf0, this clears internal state at USB reset time so the
driver can survive host OS reboots.

altos: Add one-byte SPI output routine for LPC and STM cores2016-03-26T23:07:20+00:00Keith Packardkeithp@keithp.com2016-03-25T01:25:33+00:00urn:sha1:7348cc4736c9a94f9ad299edd78199b544d0e95a
This allows for SPI output at interrupt time, one byte at a time.

This offers a faster timer callback for higher-precision operation

altos/lpc: Give up on interrupt-driven SPI driver2015-02-07T09:05:57+00:00Keith Packardkeithp@keithp.com2015-02-07T09:05:57+00:00urn:sha1:f9f235bce84df3a6c0261e9d256aac544f87f70f
There are just too many limitations in when interrupts are delivered
to make them useful. Instead, just drive the SPI directly with the
CPU. At higher spi speeds (6Mhz or more), it's probably faster to do
it this way anyways.
