Adding USB MSD implementation to the HAL: Now, when you plug the Native USB port of the Arduino DUE to your PC, it will be detected as a composite USB device: One of the devices is a USB CDC (Serial port over USB) with native USB handshake (no more overflows!!) (set SERIAL_PORT to -1 to use it as main serial port) and also, a MSD (USB Mass Storage Device) will be detected, and the SD card present on the socket will be reflected as a Removable disk on your PC)
Reimplemented SW SPI for DUE in assembler. This allows to reach 12Mhz as SPI Clock and improves 4x the transfer speed to the SD card. This is REQUIRED so access to SD from USB is usable (allows 600Kbytes/second transfer speeds)
Adjusted timings on the ST7290 u8glib so RE-ARM and RAMPS4DUE have no problems when writing to the graphics LCD. This fixes Issue #8787 - Special thanks to Bergerac56 for testinf this out !!!
Backported latest improvements and fixes from the SdFat liibrary to our own version. This includes support for CRC7 validation on commands and also, made sure that even if using software SPI implementations, SD card speed is properly adjusted when transitioning from INITIALIZATION to DATA TRANSFER mode. ALL HALs implement spiInit, even in SW SPI mode, and we NEED this change to improve 25x the transfer speed of the SD card and allow implementations of USB MSD
Some to correct missing files from previous PR to completely avoid
HardwareTimer Class (reduce overhead). Some changes to formatting.
Changes to DMA ADC to work correctly.
Change to F1 sanity check.
Fixes for the Arduino DUE HAL (Serial Port, Graphics Display, EEPROM emulation) (#8651)
* Fixing the DUE serial port assignments: Now -1 means the SAM3x USB Device emulating a serial port, and 0 means the USB to serial adapter included as a programming port
* Improving the Fast IO port access implementation on Arduino DUE
* Implemented EEPROM emulation on Due by storing data on the internal FLASH (with wear leveling)
* Implemented a Software SPI for the ST7920 graphics display for the Arduino RAMPS for DUE, as the default one in u8glib is clocking data too fast on ARM, and the display does not understand it.
* Fixing the case where the serial port selected is the USB device
* Adding configuration for the Makerparts 3D printer (www.makerparts.net)
* Tuned MakerParts acceleration on X and Y axis so it never loses steps. Also adjusted pulses per mm to match default hw configuration
* Fine tuned Maximum acceleration for MakerParts printer
* Style cleanup
* Style cleanup (2)
* Style fixes (3)

* Style changes to u8g_dev_st7920_128_64_sw_spi.cpp
* Even more improvements to the FastIO HAL for DUE. Now WRITE() is 2 ASM instructions, if value is constant, and 5 cycles if value is not constant. Previously, it was 7..8 cycles
* After some problems and debugging, seems we need to align the interrupt vector table to 256 bytes, otherwise, the program sometimes stops working
* Moved comments out of macro, otherwise, token pasting does not properly work sometimes
* Improved Software SPI implementation on DUE: Now it honors the selected speed passed to spiInit(). This allows much faster SDCARD access, improving SDCARD menus and reducing latency
* Update u8g_dev_st7920_128_64_sw_spi.cpp
* Disabling EEPROM over FLASH emulatiion if an I2C or SPI EEPROM is present
