John Safranek 8d97ee9250 Port Zephyr test sample to 3.4.0 and 4.4.0 ... Zephyr 3.5 moved the RAM disk driver from Kconfig to devicetree and 4.1 replaced CONFIG_NET_SOCKETS_POSIX_NAMES with CONFIG_POSIX_API. Port the sample to the new APIs while keeping it buildable on older Zephyr. - add ramdisk.overlay (zephyr,ram-disk node) for the FS scenarios; drop CONFIG_DISK_RAM_VOLUME_SIZE - switch to CONFIG_POSIX_API; include the POSIX time/select/socket/netdb headers in test.h and port.h, gated on ZEPHYR_VERSION_CODE >= 4.1.0 so older Zephyr keeps the BSD names from <zephyr/net/socket.h> - select RAM disk (overlay >= 3.5, else CONFIG_DISK_RAM_VOLUME_SIZE) and POSIX (CONFIG_POSIX_API >= 4.1, else the legacy symbols) in CMakeLists.txt, with ramdisk_legacy.conf / posix_legacy.conf fallbacks - tests, nofs and kbi scenarios pass on qemu_x86 with Zephyr 3.4.0 (SDK 0.16.1) and 4.4.0 (SDK 1.0.0)		2026-07-14 13:58:43 -07:00
