HardwareSerial has been tested on Uart0 (debug header) and Uart3 (i2c connector)
Software Serial has been tested to work bi-directionally at 9600 and 115200
using pins 6 and 63 on J5, and unidirectionally (write only) at 250000.
The code used to test was Teemuatlut's tmc2208 patch, and a few small changes to main used to echo recieved chars back to a host pc.
Uses PWM1 to directly control pins 4, 6 & 11 (servo 0, 1 & 3) and PWM1
generated interrupts to control other pins.
Interupt control of the servo pins had too much jitter so switched all
that we could to PWM1 direct control. The PWM1 direct control pins have
less than 1 microsecond pulse width jitter while the interrupt
controlled ones can have 20+ microseconds of jitter.
Also added insurance to the servo code in the "disable servo after move"
section.
* LCD_UBL_memory_slot_corrections
Changed the memory slot edit function to work with the
`settings.calc_num_meshes()`
* Add a little more safety margin...
* More corrections
Error handling when the EEPROM is not available.
move from legacy precise to trusty build image
fix PATH not including buildroot/bin
remove symolic link to ~/bin as trusty travis image doesn't include it in PATH anyway

Revert "Base HAL SPI Changes"
This reverts commit 2afc521b8b6a81b2281a038f1b99a69f4a008e64.
Revert "Initial HAL SPI API"

* Fix mistake in gitignore file and add in missing core files.
The missing leading slash on "lib" meant all folders names lib in the directory tree are ignored, rather than just the top level PlatformIO lib folder
* Add LiquidCrystal Library and associated headers modified to compile.
Because of the Re-ARM card's pinout there is only one SPI connected to
the RepRap Discount Full Graphic LCD display. The LCD responds to ANY
SCK transitions no matter if it's enable is inactive. The result is
garbage (usually bars) on the LCD display whenever there is SD card
activity.
This code minimizes this by only accessing the SD card when changing
directory levels if :
SDCARD_SORT_ALPHA is enabled
SDSORT_USES_RAM is true
SDSORT_CACHE_NAMES is true
The code changes result in file names being pulled from the ALPHA SORT
memory array rather than the SD card.
The code also gives the file count and file index functions their own
variables. When they shared a common variable the index function
sometimes resulted in the file count being short by 1.
=======================================================================
cardreader.cpp & pins_RAMPS_RE_ARM.h changes
Added another condition to cardreader.cpp to enable getting file names
only from RAM.
pins_RAMPS_RE_ARM.h :
Added comments about the SD card accesses and the LCD display
Combined all versions into this one.
