Set SPI_1_POWER_MANAGE and/or SPI_2_POWER_MANAGE to have the spi
blocks powered down when not in use.

altos/stmf0: Add 'ao_serial_shutdown'2019-07-16T18:04:16+00:00Keith Packardkeithp@keithp.com2019-07-16T18:04:16+00:00urn:sha1:bdcb3653bd9fb97f98773ac3bc1f87a6f52b1121
This powers down the UART logic on request.

altos/stmf0: Leave power interface disabled until needed2019-07-16T18:02:56+00:00Keith Packardkeithp@keithp.com2019-07-16T18:02:56+00:00urn:sha1:009d56b4f03c1ba3c9a36bdb54c772ad21844057
We only need the power interface when placing the chip in the lowest
power state, so don't power up the power interface clock at startup,
instead wait until later.

altos/micropeak-v2: Erase log space at end of BOOST_DELAY2019-06-19T06:16:12+00:00Keith Packardkeithp@keithp.com2019-06-19T06:16:12+00:00urn:sha1:c4b8aff07d5366cef2c7209729f6cd22fa67de0c
We have to erase the log before the flight starts, so this seems like
the latest possible moment.

altos/micropeak-v2.0: Go into standby mode after landing2019-06-18T20:02:51+00:00Keith Packardkeithp@keithp.com2019-06-18T20:02:51+00:00urn:sha1:4d4f018f22a0a9814e675a232b1c4239572bdd9a
This is the lowest power state we can reach, and consumes about 15µA
or less.

altos: add ao_time_ns API2019-02-25T23:42:25+00:00Keith Packardkeithp@keithp.com2019-02-25T23:42:25+00:00urn:sha1:cd920a0e5321166ef8b1d6afc3d63fc5de998a93
This provides nano-second resolution times by reading the systick
value (which runs at 250ns ticks on stm).

Make sure AO_TICK_TYPE is used "everywhere", instead of uint16_t or other.

altos: Fix ISR declarations to make them non-weak2019-02-22T03:40:08+00:00Keith Packardkeithp@keithp.com2019-02-22T03:26:41+00:00urn:sha1:3310b22e28d953a6569cd50e83f91c25577424a5
In my zeal to eliminate warnings, I added declarations of all ISR
functions to a shared header file. However, I managed to include the
'weak' declaration, which meant that the intended ISR functions were
as weak as the 'default' ISR functions. This left all interrupts
non-functional, which doesn't make for a happy program.

altos: Move common build definitions to src/Makefile.defs2019-02-18T21:08:23+00:00Keith Packardkeithp@keithp.com2019-02-18T20:59:05+00:00urn:sha1:7a89aa1ea7e1b02b5cd310986adf4239ec0ce91d
This cleans up the build process for all architectures, providing a
common place to specify vpath, cflags and build rules for various
common files.
