Using this slower clock eliminates sampling problems with the ADC and
cleans up the chaoskey raw data.

altos/stmf0: Clean .bin files from flash-loader dirs2016-08-02T23:55:11+00:00Keith Packardkeithp@keithp.com2016-08-02T23:53:50+00:00urn:sha1:1934468e96ea9d179abf6e3e728b6b14ce793f46
The .bin files are what the DFU utility uses to flash the boot loader
using USB.

altos/stmf0: Hook up clock output support2016-08-02T23:55:11+00:00Keith Packardkeithp@keithp.com2016-08-02T23:32:43+00:00urn:sha1:782013d0ff2c9f076952c0e172bfcb7016699d5f
This was used to try and not have two xtals on telemini, but failed
because the provided clock has too much noise.

This can't work without a lot more effort.

altos/stmf0: Rework the sram allocation to save a few text bytes2016-06-12T05:16:12+00:00Keith Packardkeithp@keithp.com2016-06-12T05:16:12+00:00urn:sha1:1704d27248f1845c545ec61cf1bad58bf41189af
Boot loaders were going over 4096 bytes of ROM. I suspect we'll need
more serious work soon.

stmf0: Do not send more data than requested for GET_DESCRIPTOR2016-06-10T05:06:30+00:00Keith Packardkeithp@keithp.com2016-06-10T05:06:30+00:00urn:sha1:36ba97fabbed2f2a4a89da5be221c630ea3ff66f
When Linux boots, it asks for only the first 8 bytes of the device
descriptor; we must limit the amount of data sent back to that amount
or USB will get wedged.

stmf0: Clear all USB state when resetting chip. Wakeup all sleepers2016-06-10T05:05:24+00:00Keith Packardkeithp@keithp.com2016-06-10T05:05:24+00:00urn:sha1:2970de9f92243b11d3beef56f3b1df3ef3579b95
When USB is reset, but the board is not power cycled, all of the
internal USB state needs to be reset, and any tasks blocked on sending
or receiving packets need to be awoken so they can go wait for USB to
start running again.

Missing a reserved address in the registers broke everything nicely,
but the priority values were also wrong - stm32f0 exposes 8 bits per
priority, like the stm32l, but it uses only the top two bits.
