2020-02-12ARC: rework setting of ARC CPU specific compiler optionsEugeniy Paltsev
It's a very rare if at all existing occasion when ARC CPU template is used as is w/o any changes - in the end it's a beauty and competitive advantage of ARC cores to be tailored for a particular use-case - and so it doesn't make a lot of sense to offer template-based "-mcpu" selection. Given for each and every platform we end-up adding quite a few more flags it's logical to move "-mcpu" selection to platform's definition as well which we exactly do here.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

Even though EM SDP is FPGA-based board and different FPGA images (known as .bit-files) are awailable for the board still there's a common subset of options we may rely on for all configs. These are: * Normalizer * Swap instructions * Simple multiplier * Barrel-shifter * Floating-point unit * Shorter instructions (code density) This among other improvements allows to compile code with 64-bit divisions, see [1].

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <trini@konsulko.com>

2017-12-11ARC: HSDK: Fixup DW SDIO CIU frequency to 50000000HzEugeniy Paltsev
DW SDIO controller has external CIU clock divider controlled via register in the SDIO IP. Due to its unexpected default value (we expected it to divide by 1 but in reality it divides by 8) SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual is 12500000Hz) and works unstable (see STAR 9001204800). So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz by switching from the default divisor value (div-by-8) to the minimum possible value of the divisor (div-by-2) in HSDK platform code.

In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit compared t previous implementation. In particular: * We used to have a generic START bit for all cores selected by CORE_SEL mask. But now we don't touch CORE_SEL at all because we have a dedicated START bit for each core: bit 0: Core 0 (master) bit 1: Core 1 (slave) * Now there's no need to select "manual" mode of core start Additional challenge for us is how to tell which axs103 firmware we're dealing with.

2017-03-24arc: dts: separate single axs10x.dts fileVlad Zakharov
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.

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.

2016-06-13board: axs10x: Flush entire cache after programming reset vectorAlexey Brodkin
Now when we have support of IOC (IO-Coherency block) cahce operations on regions are tuned to not be dummy stubs if IOC was found and enabled in the core. That makes flush_dcache_range() useless for our purposes here.
