2021-04-27teensy: Provide own implementation of gc_collect, to not use stm32.Damien George
Signed-off-by: Damien George <damien@micropython.org>
2020-12-18teensy: Fix build errors and warnings and enable -Werror.Damien George
Changes are: - Remove include of stm32's adc.h because it was recently changed and is no longer compatible with teensy (and not used anyway). - Remove define of __disable_irq in mpconfigport.h because it was clashing with an equivalent definition in core/mk20dx128.h. - Add -Werror to CFLAGS, and change -std=gnu99 to -std=c99.

2020-04-29all: Factor gchelper code to one place and use it for unix & ARM ports.Jim Mussared
No functionality change is intended with this commit, it just consolidates the separate implementations of GC helper code to the lib/utils/ directory as a general set of helper functions useful for any port. This reduces duplication of code, and makes it easier for future ports or embedders to get the GC implementation correct. Ports should now link against gchelper_native.c and either gchelper_m0.s or gchelper_m3.s (currently only Cortex-M is supported but other architectures can follow), or use the fallback gchelper_generic.c which will work on x86/x64/ARM. The gc_helper_get_sp function from gchelper_m3.s is not really GC related and was only used by cc3200, so it has been moved to that port and renamed to cortex_m3_get_sp.
2020-04-05ports: Enable error text compression for various ports, but not all.Jim Mussared
Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32, esp8266, cc3200, teensy, qemu-arm, nrf. Not enabled on others to be able to test the code when the feature is disabled (the default case).

2019-12-27ports: Allow overriding CROSS_COMPILE in a custom makefile.David Lechner
Many ports already allow overriding CROSS_COMPILE. This modifies the remaining ports to allow it as well.
2019-02-12teensy/Makefile: Use common gchelper_m3.s code from lib/utils.Damien George
2017-09-06all: Update Makefiles and others to build with new ports/ dir layout.Damien George
Also renames "stmhal" to "stm32" in documentation and everywhere else.
2017-09-06ports: Make new ports/ sub-directory and move all ports there.Damien George
This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.
