SVD - D1 v1.0 manual

Hi @duskmoon314

Google recently recommended this project to me when I was looking for the SVD allwinner D1.
I tried to do the same in relation to the manual v1.0 D1-H but had a issue during the extraction.
Do you have a script to extract the manual or is there another way?

Issues when building d1-pac due to yanked dependency

A number of versions of the riscv crate have been yanked, causing issues when building the d1-pac.

The dependency versions should be updated to riscv = "0.10.1" and riscv-rt = "0.11.0".
Will the renovate bot do this automatically, or should I create a pull request for this?

Reading and writing with different bit width need to be supported for SPI rx and tx registers

Document of SPI_RXD:

This register can be accessed in the byte, half-word, or word unit by AHB. In the byte accessing method, if there are data in RXFIFO, the top word is returned and the RXFIFO depth is decreased by 1. In the half-word accessing method, two SPI bursts are returned and the RXFIFO depth is decreased by 2. In the word accessing method, the four SPI bursts are returned and the RXFIFO depth is decreased by 4.

These registers respond to different load (lb, lh and lw) and store (sb, sh and sw) instructions in different ways.

[TODO] Refactor of the repo

To support more SoC in a more convenient way, it is better to learn from stm32-rs. My goal is to organize the repo into the following structure:

svd
  | peripherals/**.yaml         # peripherals like uart, twi, etc.
  | <soc>_unofficial.yaml       # yaml for patching
  | <soc>_unofficial.svd        # patched yaml
<soc>-pac/                      # crates' meta and generated codes

[d1-pac] `Peripherals::take()` cannot use without `critical-section`

how to call it ? thanks

22   |     let p = pac::Peripherals::take().unwrap();
     |                               ^^^^ `Peripherals` is not an iterator
     |
    ::: /home/youngday/.cargo/registry/src/mirrors.ustc.edu.cn-12df342d903acd47/d1-pac-0.0.28/src/lib.rs:1751:1
     |
1751 | pub struct Peripherals {
     | ---------------------- doesn't satisfy `Peripherals: Iterator`

Fix katyo/publish-crates

After katyo/publish-crates used cargo metadata to extract information, it seems unable to publish one package without checking the whole workspace.

[d1-pac] check with user manual v1.2/v1.3

Allwinner has released the D1-H user manual v1.2/v1.3. Need to check what has changed since v0.1/1.0 (This crate is mostly developed according to v0.1 and v1.0)

Roadmap to d1-pac/v0.1.0

TODO

more detailed description of registers

Here are the peripherals I haven't added a detailed description of registers

• THS
• IOMMU
• DSP_MSGBOX
• RISC_V_MSGBOX
• RTC
• TCON_LCD0
• TCON_TV0
• TVE_TOP
• TVE
• CSIC
• TVD_TOP
• TVD0
• I2S_PCM
• DMIC
• OWA
• AudioCodec
• USB1
• PWM

peripherals with no detailed description in the user manual

• de (seems can get from tina-linux)
• dramc (don't know where to get yet)
  • msi + memc 0x03102000-0x03301fff
• ...

check all names

• Use the same naming convention in peripherals, registers, fields, and enumerates.

riscv 0.9.0 yanked, can't compile

The 0.9.0 release of the riscv crate has been yanked:
https://crates.io/crates/riscv/0.9.0

aw-pac could just bump to the latest release, I think.
