* arc: Update variables substitutions in u-boot env filesEvgeniy Didin2018-07-121-3/+3
| | | | | | | | | | | | | 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.

* arc770: Introduce images for SD-cardsAlexey Brodkin2016-08-284-26/+101
| | | | | | | | | | | | | | | | | | | 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>
* arc770: Reduce generalizationAlexey Brodkin2016-08-281-25/+13
| | | | | | | | | | | | | | As support of ARC 770 in OpenWRT/Lede matures we don't need debug-only output binaries any longer, so purging vmlinux for AXS10x boards. 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 sourcesAlexey Brodkin2016-08-161-1/+1
| | | | | | | | | | | | | | 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.

* image.mk: clean up redundant code related to DEVICE_DTSFelix Fietkau2016-07-151-2/+1
| | | | | | | | It is used by a core build template, so the variable should be initialized and added to DEVICE_VARS in the core. Same for DEVICE_DTS_DIR Signed-off-by: Felix Fietkau <nbd@nbd.name>
* arc: Build uImage as well as vmlinux output filesAlexey Brodkin2016-06-051-8/+36
| | | | | | | | | | | | | | | | | | | | | | 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>

* linux: add support of Synopsys ARC770-based boardsFelix Fietkau2015-11-221-0/+40
This patch introduces support of new boards with ARC cores. [1] Synopsys SDP board This is a new-generation development board from Synopsys that consists of base-board and CPU tile-board (which might have a real ASIC or FPGA with CPU image). It sports a lot of DesignWare peripherals like GMAC, USB, SPI, I2C etc and is intended to be used for early development of ARC-based products. [2] nSIM This is a virtual board implemented in Synopsys proprietary software simulator (even though available for free for open source community). This board has only serial port as a peripheral and so it is meant to be used for runtime testing which is especially useful during bring-up of new tools and platforms. What's also important ARC cores are very configurable so there're many variations of options like cache sizes, their line lengths, additional hardware blocks like multipliers, dividers etc. And this board could be used to make sure built software still runs on different HW configurations.
