archs38: Introduce images for SD-cards
Historically on ARC we started from initramfs-based images because: a) It was much easier to debug especially when toolchain and other components were changing quite dynamically b) It was our usual approach for embedded Linux But now with ARC port of Lede/OpenWRT getting more stable and mature we're ready for more real-life scenarios with FS permanently stored on SD-card. This essentially benefits from ability to setup devices that survive reboots with all settings and extra packages kept in place. Still we keep an ability to build images with initramfs. This allows us to use storage-less simulators for testing still. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: John Crispin <john@phrozen.org>
