arc770: Introduce images for SD-cards 2016-08-28T11:51:42+00:00 Alexey Brodkin Alexey.Brodkin@synopsys.com 2016-08-24T14:48:12+00:00 30d75720faa8d9e92454705e15d5f9ebcb9d0c6a 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.

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.

As for uImage for nSIM it makes completely no sense because there's no way to run U-Boot on nSIM. So we remove add_arcYYY_XXX scripts making code more compact and cleaner.

arc: use patched .dts from sources 2016-08-16T10:18:28+00:00 Alexey Brodkin Alexey.Brodkin@synopsys.com 2016-08-16T11:49:16+00:00 a3cde14f5a9ef0bca820341cbbd6d5cfb80451fc Instead of using off-the-tree .dts files for ARC boards we're switching to use in-tree ones. And for that to work properly we apply upstream patch that adds currently missing "model" property.

arc: Build uImage as well as vmlinux output files 2016-06-05T21:23:57+00:00 Alexey Brodkin Alexey.Brodkin@synopsys.com 2016-05-31T17:12:21+00:00 668dbec3f4e50f9689ddfdfb4e84818fa736aa9f Initially for ARC we were building vmlinux images because it was both simpler and more convenient to debug Linux kernel in runt-time via JTAG. Now when base system works quite nice we may finally use U-Boot for loading the system image as well. Still we keep building vmlinux images as some of our boards are development boards and loading images with JTAG could be at some points very beneficial. Note for U-Boot header it's required to specify 2 values: * loading address * entry point (if it doesn't match loading address) and in case of ARC entry point (EP) not only differs from loading address but also changes from build to build due to initramfs being placed between loading address and text section. To accommodate that feature we have to calculate EP after vmlinux gets built and before call to mkimage. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
