ARC: Add support for EM Development Kit board

2018-05-31T17:13:29Z

Synopsys DesignWare ARC EM Development Kit (ARC EMDK) is an FPGA-based development platform from Synopsys aimed to speed-up development of software for ARC EM cores and entire subsystems based on ARC EM like Data Fusion, Secure and Sensor & Control subsystems. U-Boot is supposed to be used as a primary bootloader on EMDK allowing users to easily load and start their application from micro-SD card. Signed-off-by: Alexey Brodkin

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

ARC: HSDK: Enable SPI flash support

2018-04-02T09:27:56Z

HSDK board has sst26wf016 SPI flash IC which we want to support. Add SPI controller, CS-gpio and SPI flash nodes to hsdk device tree. Enable corresponding options in hsdk defconfig. For SPI write functionality to work we need [1] which adds support of sst26xxx ICs.

ARC: HSDK: Add platform-specific commands

2018-04-02T09:27:56Z

This patch add support of hsdk platform-specific commands: hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq environment variables/command line arguments hsdk_clock get - save clock frequencies to axi_freq, cpu_freq and tun_freq environment variables hsdk_clock print - show CPU, AXI, DDR and TUNNEL current clock frequencies. hsdk_clock print_all - show all currently used clock frequencies. hsdk_init - setup board HW in one of pre-defined configuration (hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 / hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4) hsdk_go - run baremetal application on hsdk configured by hsdk_init command. This patch changes default behaviour of 'bootm' command: now we are able to set number of CPUs to be kicked by setting 'core_mask' environment variable before 'bootm' command run.

ARC: AXS10x: DTS: Remove unused interrupt properties

2018-04-02T09:26:13Z

Some device tree nodes (like ethernet, ohci, ehci) in axs10x_mb.dtsi were copied from linux device tree, so they have interrupts properties. As we don't use interrupts in uboot we don't have interrupt controller node in AXS10x device tree. In result we get warnings when we compile such device tree. So remove unused interrupts properties to get rid of this warnings. Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin

arc: Add support for HS Development Kit board

2017-06-29T16:34:10Z

ARC HS Development Kit board is a new low-cost development platform sporting ARC HS38 in real silicon with nice set of features such as: * Quad-core ARC HS38 with 512 kB L2 cache and running @1GHz * 4Gb of DDR (we use only lowest 1Gb out of it now) * Lots of DesigWare peripherals * Different connectivity modules: - Synopsys HAPS HT3 - Arduino-compatible connector - MikroBUS This initial commit supports the following peripherals: * UART (DW 8250) * Ethernet (DW GMAC) * SD/MMC (DW Mobile Storage) * USB 1.1 & 2.0 Signed-off-by: Alexey Brodkin

arc: dts: separate single axs10x.dts file

2017-03-24T11:47:52Z

We want to use the same device tree blobs in both Linux and U-Boot for ARC boards. Earlier device tree sources in U-Boot were very simplified and hadn't been updated for quite a long period of time. So this commit is the first step on the road to unified device tree blobs. First of all we re-organize device tree sources for AXS10X boards. As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and AXC003 cpu tiles respectively we add corresponding device tree source files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for cpu tiles and axs101.dts and axs103.dts to represent actual boards. Also we delete axs10x.dts as it is no longer used. One more important change - we add timer device to ARC skeleton device tree sources as both ARC700 and ARCHS cores contain such timer. We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree sources as it is referenced via phandle from timer node in common skeleton.dtsi file.

arc: Rename AXS101 board to more generic AXS10x

2016-08-05T09:50:33Z

As of now we have 2 flavors of ARC SDP boards: 1) AXS101 - with ARC770 in ASIC 2) AXS103 - with ARC HS38 in FPGA Both options share exactly the same base-board and only differ with CPU-tiles in use. That means all peripherals are the same (they are implemented in FPGA on the base-board) and so generic board could be used for both. While at it: * Recreated defconfigs with savedefconfig * In include/configs/axs10x.h numerical sizes replaced with defines from linux/sizes.h for better readability.
