arc770: 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> Cc: Jo-Philipp Wich <jo@mein.io>

arc: Update variables substitutions in u-boot env files In the latest version of u-boot (2018.05) there was a swith to Hush shell for ARC AXS10x boards(arc770/archs38): commit 9249d74781e1 ("ARC: AXS10x: Enable hush shell"). In Hush shell using "$()" to declare envitonment variables is forbidden, instead of this "${}" need to be used.
