Pull Request Overview

This PR aims to add comprehensive support for the XuanTie RISC-V cores across the E, R, and C series by removing obsolete/system-specific implementations and updating build configurations.

• Legacy system initialization, startup, and trap handling files for various architectures (e.g., c907fd, c907fd-rv32, c906fdv, etc.) have been removed.
• The linker script’s minimum heap size has been increased significantly, and the BSP compile configuration JSON has been updated to include additional board configurations.

bsp/xuantie/libraries/xuantie_libraries/chip_riscv_dummy/src/arch/*	Removal of legacy system, startup, and trap handling code for various chip variants to consolidate or replace with new implementations
bsp/xuantie/libraries/xuantie_libraries/chip_riscv_dummy/gcc_flash_xiaohui.ld	Increased __min_heap_size value to support new platform memory requirements
.github/ALL_BSP_COMPILE.json	Updated BSP sub-configurations to include new board variants

bsp/xuantie/libraries/xuantie_libraries/chip_riscv_dummy/src/arch/c907fd/system.c:1

• Multiple system initialization and trap handling files have been removed across various architectures; please confirm that all dependent modules have been updated to use the new consolidated support for RISC-V cores to avoid unresolved references.

/* entire file removal */

bsp/xuantie/libraries/xuantie_libraries/chip_riscv_dummy/gcc_flash_xiaohui.ld:24

• The minimum heap size has been increased from 0x200 to 0x20000; please verify that this new value meets the memory requirements of the updated configurations and does not introduce unintended memory overhead.

__min_heap_size = 0x20000;
