docs: Documentation improvements

* Move supported toolchain information from application docs to
README.md to avoid duplicatiing it on all supported examples.
* Move supported platforms description from docs/prerequisites.md to
README.md to list and describe the supported platforms in one place.
* Add supported versions information to supported targets.

 ## Supported Targets
 
-* [Corstone-300](https://developer.arm.com/Processors/Corstone-300)
+Arm Corstone-3xx targets includes an example subsystem based on the Cortex-M
+CPU and Ethos NPU, alongside a range of other components in a scalable and
+flexible reference package. This enables designers to build secure,
+AI-capable SoCs faster.

+## Supported Toolchains
+
+* Arm Compiler for Embedded (armclang)
+* Arm GNU Toolchain (arm-none-eabi-gcc)
 
+> Note:
+  The build script `./tools/scripts/build.sh` assumes
+  `Arm Compiler for Embedded (armclang)` by default, append the extra option
+  `--toolchain GNU` to build using Arm GNU Toolchain.

 # Prerequisites
 
-## Setting up the platforms
-
-This reference integration supports [Arm ecosystem FVPs](https://developer.arm.com/downloads/-/arm-ecosystem-fvps).
-
-The Corstone-310 model is a reference subsystem for a secure SSE-310 SoC
-aligned with the Arm MPS3 development platform. It is based on a Cortex®-M85
-processor and an Ethos-U55 neural network processor and the DMA-350
-Direct Memory Access controller. Follow the [link](https://developer.arm.com/downloads/-/arm-ecosystem-fvps)
