*	altos: Make stdio 8-bit clean by making pollchar return int	Keith Packard	2012-11-30
\| \| \| \| \| \| \| \| \| \|	We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Switch drivers to ao_arch_block/release_interrupts	Keith Packard	2012-10-25
\| \| \| \| \| \|	Stop using cli/sei, which are avr-specific Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Replace __critical usage with ao_arch_critical as needed	Keith Packard	2012-10-25
\| \| \| \| \| \| \| \| \| \| \| \| \|	sdcc offers __critical as a machine-independent way to block interrupts, but as gcc doesn't, we need to use a compiler-independent construct instead. ao_arch_critical has been around since the AVR port, but some old __critical usages remained. This fixes a bunch of random hangs when communicating with MM over USB or the radio as the various stdio loops were running without interrupts blocked between the test and the sleep.

*	altos: reorder stm USB state stores to avoid races	Keith Packard	2012-06-27
\| \| \| \| \| \| \| \| \| \| \| \| \|	Must set ao_usb_in_pending before telling USB about new data or an interrupt could arrive at the wrong time to clear it. Same for ao_usb_in_flushed. Without these changes, I've seen the USB bus lock up on occasion, waiting for an IN packet to consume data, but with no IN data pending in the hardware.

*	altos: stm: delay during USB config with pull-up off	Keith Packard	2012-05-07
\| \| \| \| \| \| \|	This makes sure that a reboot will reliably cause the device to disconnect from the USB bus. Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Starting to write cc1120 driver	Keith Packard	2012-04-17
\| \| \| \| \| \| \|	This does "something" in radio test mode, appearing to generate a 730MHz signal. Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Correct STM USB driver	Keith Packard	2012-04-14
\| \| \| \| \| \| \|	Configure endpoint registers correctly now. Restructure code to make sure we send the right IN packets. Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Massive product config cleanup	Keith Packard	2012-04-14
\| \| \| \| \| \| \| \|	Support multiple serial ports more cleanly Split out parts of ao.h into separate feature header files Signed-off-by: Keith Packard <keithp@keithp.com>
*	altos: Add STM USB driver	Keith Packard	2012-04-14
