2017-10-10atmel-samd: Add support for internal filesystems. (#311)Scott Shawcroft
* atmel-samd: Add support for internal filesystems. This allows us to re-enable `os`. `random` is also enabled because it solely depends on `os`. Fixes #266. Its also a pre-requisite for #260. * atmel-samd: Update SAMD51 linker script comments and MICROPY_MAX_STACK_USAGE enabling.
2017-09-28Add support for patching newer ASF4 code. (#292)Scott Shawcroft
* atmel-samd: Support patching after updating ASF4. This makes it possible to automatically fix newer code. * atmel-samd: Update ASF4 to include flash APIs for SAMD51. This is the first automatic update that has caused a few deletions where code was previously copied instead of moved. This is a prerequisite for #260.
2017-09-22Move to ASF4 and introduce SAMD51 support. (#258)3.0.0-alpha.0Scott Shawcroft
* atmel-samd: Remove ASF3. This will break builds. * atmel-samd: Add ASF4 for the SAMD21 and SAMD51. * Introduce the supervisor concept to facilitate porting. The supervisor is the code which runs individual MicroPython VMs. By splitting it out we make it more consistent and easier to find. This also adds very basic SAMD21 and SAMD51 support using the supervisor. Only the REPL currently works. This begins the work for #178.
