Introduce a Kconfig choice between SOC_K230 and SOC_K230D to support different chip variants. SOC_K230D targets the ATK-DNK230D board with 128MB DDR, while SOC_K230 serves as the default for other K230 boards. Key changes: - Replace single BOARD_C908 config with a choice menu for SoC variant - Move common selects (ARCH_RISCV64, RT_USING_CACHE, ARCH_MM_MMU, etc.) into each SoC config entry - Add ARCH_RISCV_XUANTIE select for Xuantie processor support - mem_layout.h: define per-SoC default memory sizes with #if defined() blocks, add #error guard when no SoC is selected - Fix typo: Kerenl -> Kernel in memory layout ASCII diagram Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

board.h: Remove unused peripheral base address defines for blocks that are not currently supported (SRAM, GSDMA, DECOMP, ISP, VPU, GPU, VO, DSI, Audio, USB2, SDHC, BootROM, Security, DDRC, XIP Flash, etc.). This reduces clutter and keeps only actively used hardware definitions. board.c: Add DBG_TAG/DBG_LVL configuration to enable debug logging via the ulog framework. Replace Chinese comments with English descriptions for better upstream readability. Add LOG_I/LOG_D trace points in primary_cpu_entry() and rt_hw_board_init() to aid bring-up debugging.

Change LOG_I to LOG_D for the "rtc driver register OK" message to reduce console noise during normal boot. Also remove the unnecessary trailing newline character from the log message. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Kconfig: Introduce ARCH_RISCV_XUANTIE option for Xuantie-based SoCs and CONFIG_XUANTIE_SVPBMT under RT_USING_SMART to enable Svpbmt extension support used by the Xuantie C908 core. mmu.c: Several improvements for MMU management: - Add dcache flush after populating early page table entries to ensure they are visible to the MMU hardware before enabling address translation - Handle the case where v2p translation fails during aspace switch for low physical addresses below KERNEL_VADDR_START, falling back to direct physical address (needed during early K230 bring-up) - When ARCH_REMAP_KERNEL is enabled, set up an identity map guard for low physical memory during aspace switch to validate boot context liveness during the transition away from the early page table - Fix pointer arithmetic in _init_region() with explicit rt_ubase_t casts to avoid potential type promotion issues Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
