update the boot crate to use llvm_asm!
add all the PIO registers/pins/etc
gpio ExtiPin patterns
generate UART1-4 device/reg impls with a macro
switch UART device to have aliased registers instead of multiple register blocks and type state
CCU device for peripheral resets/etc
use Infallible instead of Void
BSP crates: pine-a64-lts and pinephone
PR on bounded-regs for having a field named Width breaking things

Stuff for the PinePhone BSP crate

PinePhone debug UART is UART0, PB8/PB9

pine-a64-rust-workspace's Issues

Figure out the u-boot SPL issue

using SPL from apritzel/u-boot.git works, but from upstream doesn't for some reason

spl from https://github.com/apritzel/u-boot.git, branch: sunxi64-image-20180316
sudo dd if=spl/sunxi-spl.bin of=/dev/sda bs=8k seek=1

u-boot from upstream
sudo dd if=u-boot.itb of=/dev/sda bs=8k seek=5
