Factor out of external flash as well. 2018-11-15T02:30:47+00:00 Scott Shawcroft scott@tannewt.org 2018-11-15T02:30:47+00:00 urn:sha1:b67c53edfaa5792b8cfb38976a9853a1224acc50 Plus some cleanup. Fixes #1324 Move atmel-samd to tinyusb and support nRF flash. 2018-11-09T01:25:30+00:00 Scott Shawcroft scott@tannewt.org 2018-10-20T01:46:22+00:00 urn:sha1:9d91111b1b6a1eee77a88b13faf695ee0c5caea3 This started while adding USB MIDI support (and descriptor support is in this change.) When seeing that I'd have to implement the MIDI class logic twice, once for atmel-samd and once for nrf, I decided to refactor the USB stack so its shared across ports. This has led to a number of changes that remove items from the ports folder and move them into supervisor. Furthermore, we had external SPI flash support for nrf pending so I factored out the connection between the usb stack and the flash API as well. This PR also includes the QSPI support for nRF.
