v0.7.0-remake (#168)
* Literally clear the repo to nothing for starters

* The screen color changes with key presses

There's enough code here that the screen color can change when you press the keys. Right now it's most all unsafe code directly in the example file. The strange thing is that llvm is making us define atomic helper functions when it's not supposed to do that, so we need to investigate more before proceeding too much.

* can't tell if this is broken or if mgba is busted on mac

* unix dumper

* don't panic

* oops

* GbaCell into its own file, also i had broken the rt irq handler.

* closer to an acceptable demo.

* make IrqFn into just an alias.

* wrap most current mmio types.

* more stuff

* Use paste to remove a whole bunch of repetition (#166)

* gba cells are "unwind safe", they can't be in a bad intermediate state, that's the point

* Once again we must thank Yandros for saving us from ourselves.

* assembly updates.

* oops

* finish video MMIO basics, no docs yet.

* small note.

* simplify asm irq handler stack usage.

* ewram support.

* more cell stuff.

* Remove the non-Zlib dependency, sorry Sp00ph :(

* add proper dma support.

* small docs improvement.

* bitmap and oam declarations

* more macros

* single bit constants will be extremely useful

* add `IntrWait`

* rename for clarity

* improvements

* use the new constant

* improve sound support

* timers

* key support

* add a prelude module.

* fix doc

* more and more assembly (mem fns will need global_asm probably)

* more comments.

* comment updates.

* readme

* more video support, and put IrqFn alias into interrupts module.

* finish working in the EABI code.

* CI config.

* funding file.

* rustc plz inline these functions when you can :3

* "rt0" is unnecessarily cryptic

* overhaul the readme.

* phrasing

SioSerial improvements (#100)
Make a few improvements to the SioSerial struct:
- Have init() return Self. It's more ergonomic to create and initialize
the empty struct in one call.
- Enable FIFO. The GBA has a 4-byte UART FIFO. This makes it less
likely to lose received bytes.
- Derive Clone on SioSerial so it can be split and shared with an
interrupt.
- Derive Debug on SioError so results can be unwrapped.

Add Serial and GPIO registers and implement embedded_hal traits (#96)
* Add Serial and GPIO registers and implement embedded_hal traits

Use VolAddress and phantom_fields to populate the SIOCNT, RCNT, and
SIODATA8 registers. Implement embedded_hal serial traits around an empty
SioSerial struct.

Hide serial read and write traits behind a "serial" feature flag
to make embedded-hal and nb dependencies optional.

* UART echo example

Enable the serial feature for this example. Provide a pinout
diagram to assist people with wiring up a USB to UART adapter.

Lokathor ac031627c8 Update IME to be u16 sized, avoid newtype_enum
newtype_enum makes an enum, but an enum can be UB if it's no a valid bit pattern. We should avoid having registers mapped to enum types.

Ian Pickering d15168068b Add __IRQ_HANDLER symbol to hello_magic example
The hello_magic example does not depend on the gba crate, but the crt0
now assumes that the symbol for the interrupt handler which is defined
in it will be present, as interrupts ought to be handled in some
manner. If neither the symbol or the crate are added then the linker
will give an error, but if anything in the gba crate is used also then
the symbol will be brought in, so defining it manually also would
cause a duplicate definition error. In the future something like
cortex-m-rt's `exception!` macro could be used to better document how
to define this symbol (all their examples depend on at least one
symbol from their runtime library, so they don't have this problem).
