+# Deprecation Notice
 
-# cortex-a
+This crate has been renamed to `aarch64-cpu`. Please find it at
+- https://github.com/rust-embedded/aarch64-cpu
+- https://crates.io/crates/aarch64-cpu
 
-Low level access to Cortex-A processors.
+Version `8.1.1` will be the last version of this crate and has been added to get this message out.
+To keep the version history sane, the first version of `aarch64-cpu` starts at `9.0.0`.
 
-## Currently Supported Execution States
-
-- [x] AArch64
-- [ ] AArch32
-
-## Minimum Supported Rust Version
-
-Requires a recent nightly of Rust if the (default) `nightly` feature is enabled. Without this the
-register access module is not available.
-
-## Usage
-
-Please note that for using this crate's [register definitions](src/registers) (as provided by
-`cortex_a::registers::*`), you need to also include
-[`tock-registers`](https://crates.io/crates/tock-registers) in your project. This is because the
-`interface` traits provided by `tock-registers` are implemented by this crate. You should include
-the same version of `tock-registers` as is being used by this crate to ensure sane
-interoperatbility.
-
-For example, in the following snippet, `X.Y.Z` should be the same version of `tock-registers` that
-is mentioned in `cortex-a`'s [`Cargo.toml`](Cargo.toml#L27).
-
-```toml
-[package]
-name = "Your embedded project"
-
-# Some parts omitted for brevity.
-
-[dependencies]
-tock-registers = "X.Y.Z"
-cortex-a = "A.B.C"       # <-- Includes tock-registers itself.
-```
-
-### Example
-
-Check out https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials for usage examples. Listed
-below is a snippet of `rust-raspberrypi-OS-tutorials`'s early boot code.
-
-```rust
-use cortex_a::{asm, registers::*};
-use tock_registers::interfaces::Writeable; // <-- Trait needed to use `write()` and `set()`.
-
-// Some parts omitted for brevity.
-
-unsafe fn prepare_el2_to_el1_transition(
-    virt_boot_core_stack_end_exclusive_addr: u64,
-    virt_kernel_init_addr: u64,
-) {
-    // Enable timer counter registers for EL1.
-    CNTHCTL_EL2.write(CNTHCTL_EL2::EL1PCEN::SET + CNTHCTL_EL2::EL1PCTEN::SET);
-
-    // No offset for reading the counters.
-    CNTVOFF_EL2.set(0);
-
-    // Set EL1 execution state to AArch64.
-    HCR_EL2.write(HCR_EL2::RW::EL1IsAarch64);
-
-    // Set up a simulated exception return.
-    SPSR_EL2.write(
-        SPSR_EL2::D::Masked
-            + SPSR_EL2::A::Masked
-            + SPSR_EL2::I::Masked
-            + SPSR_EL2::F::Masked
-            + SPSR_EL2::M::EL1h,
-    );
