2021-03-07Automatically count EXTERNAL_FLASH_DEVICES (mk2)Jeff Epler
Instead of counting words in make, which is slightly awful, notice that possible_devices is local to external_flash.c, so we can declare the array with an automatic bound, and then get the count as the element-count (MP_ARRAY_SIZE) of the array. Since EXTERNAL_FLASH_DEVICE_COUNT is no longer a global macro, switch a few sites to using EXTERNAL_FLASH_DEVICES in `#if` checks instead.

2020-11-28Add movable allocation system.Christian Walther
This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review.

2020-06-23atmel-samd: Add SAM E54 Xplained boardJeff Epler
Few peripherals are actually tested. However, USB, I2C and GPIO seem to work. Most pins are silkscreened with the "PX00" style, so the board module only includes the small number that are screened differently. The default SPI, I2C, and UART are the ones on the EXT2 header. This is arbitrary, but the I2C on this connector is shared with the on-board I2C devices and the PCC header, making it the most versatile.

2019-12-10supervisor: external_flash: don't call m_free when it's badJeff Epler
It's extremely dubious that we have these handles that we think are to GC'd memory at a time when the gc pool may not be initialized. Hopefully, they WERE valid GC memory and are undisturbed by the teardown of the interpreter that can lead to this state. In this case, don't try to m_free them, the memory will become free when the GC heap is reinitialized. Closes: #2338 (together with previous commit)
