ARC: HSDK: Fix timer frequency value

2018-09-05T15:11:45Z

CPU (and hence cpu timers) on HSDK board runs at 500MHz after preloader so fix wrong CPU frequency value in hsdk.dts Signed-off-by: Eugeniy Paltsev

AXS10x: add spi flash support

2018-07-31T04:49:47Z

AXS10x boards have n25q512 spi flash IC, so add corresponding nodes to device tree and enaple corresponding options in defconfig. Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin

GPIO: CREG: improve flexibility of hsdk-creg-gpio driver

2018-07-31T04:49:47Z

CREG GPIO is a driver for weird soc-specific output ports, which are controlled by some fields in memory mapped register. Example: 31 9 7 5 0 < bit number | | | | | [ not used | gpio-1 | gpio-0 | <-shift-> ] < 32 bit register ^ ^ | | write 0x2 == set output to "1" (activate) write 0x3 == set output to "0" (deactivate) As of tooday we only support fixed (hardcoded) bit per gpio line, activate / deactivatei and shift values. Fix that by read them from device tree to be able to use this driver for other boards. Remove "hsdk" prefix from compatible string as this driver can be used with different boards like HSDK, AXS101, AXS103, etc. Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin

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
