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)
1. Exclude the file regress.c from the Zephyr testing sample. The test
is covered in many other environments already. The test needs some
retooling to fit in with the Zephyr build, as it is a standalone
application with a main() function and it depends on a testing build
of libwolfssh.
2. Whitespace.
