Pull request overview
Adds a new src/port/wolfHAL/ port intended to let wolfIP run on any target that provides wolfHAL whal_Eth / whal_EthPhy, with STM32H563ZI Nucleo-144 as the first reference board and a standalone Makefile-based bare-metal build.
Changes:
- Introduces a generic wolfHAL-based link-layer adapter (
wolfhal_eth.c/.h) that bridges wolfIP ll_dev poll/send towhal_Eth_Recv/whal_Eth_Sendand starts the MAC after PHY negotiation. - Adds a generic bare-metal
main.cfor bringing up wolfIP, configuring a static IPv4 address, and starting a TCP echo server. - Adds a complete STM32H563ZI Nucleo board package (startup/IVT/linker/board init/syscalls + board.mk) and a port-local build system +
.gitignore.

Summary
whal_Eth_Recv/whal_Eth_Send
Structure
src/port/wolfHAL/
├── Makefile, main.c, wolfhal_eth.c/h # Generic (board-independent)
└── boards/stm32h563zi_nucleo/ # Board-specific: clock, GPIO, ETH, UART, linker
Adding a new board requires only a
boards/<name>/directory with board.c/h, board.mk, and bare-metal startup files. The generic main.c and wolfhal_eth.c are shared across all boards.Build
Requires arm-none-eabi-gcc and wolfHAL cloned as a sibling directory (overridable via WOLFHAL_ROOT).
Testing

ping 192.168.1.100on my host PC. I successfully got a responses back.
