mjb/altos/src/avr, branch master

altos: Move common build definitions to src/Makefile.defs

2019-02-18T21:08:23+00:00

This cleans up the build process for all architectures, providing a common place to specify vpath, cflags and build rules for various common files. Signed-off-by: Keith Packard

altos: Declare task stack as union of uint8_t and uint32_t

2019-02-18T21:08:23+00:00

Support -Wcast-align and -Wpointer-arith while still allowing architectures to pick whether they want an 8-bit or 32-bit stack. Signed-off-by: Keith Packard

altos: Clean up AO_ROMCONFIG bits

2018-10-13T15:23:25+00:00

Remove address parameter (doesn't work with gcc), create shared ao_romconfig in kernel. Signed-off-by: Keith Packard

altos: Add generic LED driver.

2018-10-13T15:23:25+00:00

This driver uses the generic GPIO functions and allows per-LED port and pin configuration. It supports up to 32 LEDs. Rename SoC-specific LED drivers. Remove enabled parameter to ao_led_init Signed-off-by: Keith Packard

altos: Eliminate 'pin' field from GPIO functions

2018-10-13T15:23:25+00:00

This was used with the 8051 bit-addressing mode to provide single-instruction access to GPIO pins. Signed-off-by: Keith Packard

altos: Remove 8051 address space specifiers

2018-10-13T15:22:50+00:00

Signed-off-by: Keith Packard

altos: Make CDC ACM 'line coding' public

2017-05-05T05:10:36+00:00

This allows other systems to see what baud rate the host has requested. Signed-off-by: Keith Packard

altos/avr: Avoid warning about unused args in stdio_put and stdio_get

2017-02-20T20:34:01+00:00

Signed-off-by: Keith Packard

Switch from GPLv2 to GPLv2+

2016-07-12T22:41:41+00:00

Signed-off-by: Keith Packard

altos: Declare port register type only in arch header

2014-11-06T23:58:42+00:00

Instead of defaulting to 8 bits, explicitly require declaration of the type of the port register for each architecture. Signed-off-by: Keith Packard
