Zynq7000 Rust Run-Time Support

Startup code and minimal runtime for the AMD Zynq7000 SoC to write bare metal Rust code. This run-time crate is strongly based on the startup code provided by AMD.

Some major differences:

• No L2 cache initialization is performed.
• MMU table is specified as Rust code.
• Modification to the stack setup code, because a different linker script is used.

This crate pulls in the cortex-a-rt crate to provide ARM vectors and the linker script.

Features

• rt is a default feature which activates the run-time.

Re-Generating the MMU table

The MMU table is a static flat map of 4096 entries for each 1 MB in the memory map. It was generated using the mmu-table-gen tool.
