arc: enable building of all dtbs

2015-10-27T21:12:13+00:00

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs are not really dependent on a platform being enabled or any other kernel config, so for testing coverage it is convenient to build all of the dtbs. This builds all dts files in the tree, not just targets listed. Signed-off-by: Rob Herring Acked-by: Vineet Gupta

arc: use common make variables for dtb builds

2015-10-27T21:12:13+00:00

Use dtb-y and always make variables to build dtbs instead of explicit dtbs rule. This is in preparation to support building all dtbs. Signed-off-by: Rob Herring Acked-by: Vineet Gupta

ARC: [plat_arcfpga]->[plat_sim]

2015-06-19T12:39:26+00:00

* Remove remanants of legacy ARC FPGA platforms (AA4, ML509...) * Only nsim simulation platform is left, rename platform accordingly * AA4 DT stuff is compatible with nsim for ARC700 so rename it too Signed-off-by: Vineet Gupta

ARC: [kbuild] Avoid DTB rebuilds if DTS are untouched

2013-04-17T12:49:14+00:00

Currently, for every ARC kernel build I see the following: --------------->8----------------- DTB arch/arc/boot/dts/angel4.dtb.S AS arch/arc/boot/dts/angel4.dtb.o LD arch/arc/boot/dts/built-in.o rm arch/arc/boot/dts/angel4.dtb.S <-- forces rebuild next iter CHK kernel/config_data.h --------------->8----------------- This is because *.dts.S is intermediate file in dtb generation and is by default deleted by make which needs a ".SECONDARY" hint to NOT do so. This could have ideally been done in scripts/Makefile.lib - for benefit of all, however .SECONDARY doesn't seem to work with wildcards. Thanks to Stephen for suggesting .SECONDARY (vs .PRECIOUS) and making that work using a non wildcard version in arch makefile. Thanks to James Hogan for pointing out that *.dtb.S now needs to be added to clean-files Signed-off-by: Stephen Warren Signed-off-by: Vineet Gupta

ARC: [plat-arcfpga]: Enabling DeviceTree for Angel4 board

2013-02-15T17:45:57+00:00

* arc-uart platform device now populated dynamically, using of_platform_populate() - applies to any other device whatsoever. * uart in turn requires incore arc-intc to be also present in DT * A irq-domain needs to be instantiated for IRQ requests by DT probed device (e.g. arc-uart) TODO: switch over to linear irq domain once all devs have been transitioned to DT Signed-off-by: Vineet Gupta Cc: Grant Likely Cc: Arnd Bergmann

ARC: [DeviceTree] Basic support

2013-02-15T17:45:55+00:00

This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".
