From aaf7be96c2c14aa190d39e50fa3606389eafda8e Mon Sep 17 00:00:00 2001 From: "Ying-Chun Liu (PaulLiu)" Date: Thu, 3 Jul 2025 07:28:07 +0100 Subject: efi: add EFI_SYSTEM_TABLE_POINTER for debug Add EFI_SYSTEM_TABLE_POINTER structure for remote debugger to locate the address of EFI_SYSTEM_TABLE. This feature is described in UEFI SPEC version 2.10. Section 18.4.2. The implementation ensures support for hardware-assisted debugging and provides a standardized mechanism for debuggers to discover the EFI system table.
