* Starts to rework build framework.
* Fully reworks build API, builds with RP2040 again.
* Adds docs and doc generation.
* Renames source to register_definitions, makes Target.configure optional.
* Adds issue tracking links.
* Drops CI for now

* start on new docs to match api
* tweak the MicroZig dependency tree
* use microzig_options
* remove empty.zig
* add test programs
* keep it to one arch, bump flash for debug
* new for loop syntax and recursive dependencies allowed for removal of import-module.zig
* fix chip standard path
* move to build.zig
* update template too
* stm32f407: add Uart support
* lpc1768: add cpu_frequency in board and chip
Allow using them with microzig Uart, which ensures the clock is present
* lpc1768: fix UART2 and UART3 peripheral clock register
They are in the PCLKSEL1 register, not PCLKSEL0
* uart-sync: use native microzig Uart, target different boards/chips
The previous example was lpc1768 specific, this new example should work with all
board and chips which implement the microzig Uart functionality. Instead of 4
LEDs, the new example uses a single LED to provide minimal debugging
capabilities if something does not work correctly.
This allows building this example for the stm32 f3 and f4 discovery boards.
* Add stm32f429 registers
Generated using regz with:
./regz STM32F429.svd > registers.zig
Using this SVD:
871761af63/data/STMicro/STM32F429.svd
* Add initial support for the stm32f429idiscovery eval board
Blinky example working on the board
* Add stm32f407 registers
Generated using regz with:
./regz STM32F407.svd > registers.zig
Using this SVD:
871761af63/data/STMicro/STM32F407.svd
* Add initial support for the stm32f4discovery eval board
The blinky example is working on the board
* mostly implemented, need different patch in order to wire it in
* add generated code
* turned interrupts back on
* fix symbol names for avr
* export in cpu file
* Emits a function instead of a `void` symbol.
* add interrupt test to avr
* Removes invalid comment.

* build.zig: Trivial rename around UART test
* mmio: Add writeRaw() to set a full register
* UART: Add TODO for auto baud rate detection
* STM32F30x Initial USART1 output/transmit support
All code assumes default chip clock configuration.
Code assumes STM32F303xB / STM32F3030xC.
Code supports only 8 data bits, 1 stop bit.
* stm32f3discovery @panic() to UART1
This is done by implementing `debugWrite()` for the board,
which only initializes UART1 if that was not yet done,
and flushes afterwards to make sure the host receives all.
* stm32f303: Support UART1 reader
This is done by implementing `rx()` and `canRead()`.
* stm32f303 UART1 correctly support 7 and 8 bits
This includes correctly masking the parity bit
on reads.
* stm32f3 UART1 support 0.5/1.5/2 stop bits
* stm32f303 UART1 simplify parity code
* Make work with regz-generated registers.zig change
* After #23 repair Reset on stm32, lpc1768
* Support disabling UART test configs
* `zig build [install]` also builds .bin files
* Support one blinking LD3 on STM32F3DISCOVERY board
These changes were mostly copied from the stm32f103 already there.
But this is far from complete, many shortcuts were taken:
- Most importantly,
only a single LED on the board, and its port/pin, is supported,
viz. the 'north' LD3 on bit 9 of GPIOE.
- Setting RCC_AHBENR bit IOPEEN ("I/O port E clock enable") is done
at the same as setting the mode (input or output) on one of its pins.
No idea if that is the right place to do this.
- In cortex-m4.zig, using 'max ram' as the initial stack pointer.
The rest is completely copied from cortex-m3.zig.
- UART test is disabled.
(It seems to assume mbed-lpc1768 pin numbers.)
* Nicer initial stack pointer: exactly after RAM
* Fix build error
(How was this code working earlier?!?)
* stm32f30x: Allow all 16 pins, all GPIOx registers
* STM32F3DISCOVERY: map all LED pins
* create linkerscript step
* catch up to master, do some cleanup
* remove references to micro_linker
* commas
* remove package
* use root path trick for cpus and chips
* remove duped file
