altos/avr: telescience doesn't have room for the flash write code2011-10-12T00:57:32+00:00Keith Packardkeithp@keithp.com2011-10-12T00:48:11+00:00urn:sha1:75960500d1f290fa9f82183431443ac122f12c19
This is useful for debugging the SPI and flash drivers, but not
necessary in production code.

Not that we have any way of knowing how much stack we're using, but at
least this seems to work.

altos/avr: Clear SPI receive buffer before clocking new data in2011-10-12T00:57:32+00:00Keith Packardkeithp@keithp.com2011-10-12T00:10:45+00:00urn:sha1:3a28846d3ff8f82b0e97c211b9debf6d67ee5af5
I don't know why this is necessary, but the receive buffer gets
'extra' data added somehow.

Wrap the argument to ao_arch_critical in do { } while (0); to make
sure it gets correctly checked as a statement.
