// AST1060-EVB SPDM Requester-Responder Test Configuration
// ARM Cortex-M4F with UART console
//
// Three-process system for testing SPDM requester/responder communication:
//   1. mctp_loopback_server  - Routes MCTP messages between requester and responder
//   2. spdm_requester        - SPDM requester using spdm-lib requester API
//   3. spdm_responder        - SPDM responder using spdm-lib responder API
//
// Memory Layout (PMSAv7-friendly, power-of-2 aligned regions):
//   0x00000000 - 0x00000500: Vector table + kernel annotations (1280 bytes)
//   0x00000500 - 0x00020000: Kernel flash (~127KB)
//   0x00020000 - 0x00028000: mctp_loopback_server flash (32KB)
//   0x00028000 - 0x00040000: spdm_requester flash (96KB)
//   0x00040000 - 0x00058000: spdm_responder flash (96KB)
//   0x00058000 - 0x00070000: Kernel RAM (96KB)
//   0x00070000 - 0x00078000: mctp_loopback_server RAM (32KB)
//   0x00078000 - 0x00090000: spdm_requester RAM (96KB)
//   0x00090000 - 0x000A0000: spdm_responder RAM (64KB)
//
// Total: 0xA0000 = 640KB (fits within the 640KB usable window of the AST1060's 768KB SRAM).
