+Disclaimer text:  // High-density devices only (Maple Native)
+
+
+Board portability is implemented by adding a header file to ./libmaple with the
+name of the BOARD target, and then editing libmaple.h to add this file as an
+option.
+
+A pin maple file should be added to ./notes describing the pin numbering
+
+Files to check by hand:
+#   adc.c
+#   adc.h
+#   exc.c
+#   exti.c
+#   exti.h
+#   flash.c
+#   flash.h
+#   gpio.c
+#   gpio.h
+#   libmaple_types.h
+#   nvic.c
+#   nvic.h
+#   rcc.c
+#   rcc.h
+#   ring_buffer.h
+#   rules.mk
+#   spi.c
+-   spi.h
+#   syscalls.c
+#   systick.c
+#   systick.h
+#   timers.c
+#   timers.h
+#   usart.c
+#   usart.h
+#   util.c
+#   util.h
+#   libmaple.h
+#   usb/*
+#   wirish/*
+
+
+ADC Notes:
+    only using ADC1?
+    untested
+
+EXTI Notes:
+    need to update huge table in comments?
+    untested
+
+NVIC Notes:
+    I don't think NVIC_ISER3 and NVIC_ICER3 actually exist?
+    Only CANBUS and USB OTG use interrupts above #63, but I updated the nvic code anyways
+
+RCC Notes:
+    Added some clock stuff to all boards even though they aren't usable... blah.
+
+SPI Notes:
+    SPI3 is only in XL chips so didn't really handle that
+
+TIMER Notes:
+    High-density devices add an advanced timer (TIMER8) and another normal one (TIMER5).
+    TIMER6 and TIMER7 are much less useful.
+    There is some partial progress towards adding timer5/timer8 functionality,
+    but not much. This should probably all be rewritten.
+
+USART Notes:
+    The USART/UART nomeclature is a little mixed up.
