dechao_gong f156812c0c arch/arm: add Realtek AmebaSmart (RTL8730E) CA32 support ... Add NuttX support for the Realtek AmebaSmart (RTL8730E) running on the CA32 (Cortex-A32) application core, with the KM4/KM0 cores kept as vendor firmware (KM4 acts as the WiFi network processor over WHC IPC). Stage 1 bring-up, hardware verified: - CA32 boot / exception vectors / MMU + page allocator / heap - LOGUART console (RX via KM0-owned IPC + shared memory) - IRQ controller, timer, serial - On-chip SPI NOR flash MTD -> littlefs mounted at /data - WHC-host WiFi netdev (STA): scan / connect / DHCP, verified end to end (association -> 4-way -> DHCP -> ping, bidirectional TCP) IC-agnostic Ameba glue is shared from arch/arm/src/common/ameba via a relative VPATH entry (matching the rtl8721dx pattern), which also avoids the empty mkdeps --dep-path that a leading-":" VPATH entry produced and which intermittently broke parallel .ddc dependency generation. The FIP packaging / flash image assembly is driven by common/ameba/tools/ameba_smart_flash.sh from the board scripts. Vendor blobs and build artefacts under the board prebuilt/ directory are kept out of the tree via prebuilt/.gitignore.
