arc-fixes-for-2019.04-rc1
A couple of trivial fixes and improvements for ARC Most notable are: * Move of ENV_SIZE/ENV_OFFSET to Kconfig * Fix with private structure allocation for arc_uart * Definition of CONFIG_SYS_CACHELINE_SIZE useful for building drivers

arc-fixes-for-2020.01-rc2
ARC fixes for v2020.01-rc2 The main change is move to DM_MMC of yet 2 another ARC boards: AXS101 & IoTDK. Among that we improve handling of stock-formatted SD-cards of high volume on EM SDP as well as introduction of reset driver for HSDK which is required for prepser reinitialization of some peripherals like USB etc.

arc-fixes-for-2020.04-rc2
As usual a bit late a couple of tiny fixes and improvements for ARC. 1. Switch from ARC UART to a convenient DW UART on ARC simulation platforms. This became avaialble when nSIM got support of that much more standard UART (starting from nSIM v2019.06). FWIW also available now in Free nSIM [1]. This among other things allows us finally to use the same one binary on all our simulators & FPGA-based emulators. 2. Disable networking support on simulated platforms as there's no network interface in them. 3. Add Virtio net & block devices for the configuration supported by QEMU so that we may leverage those virtual peripherals and in fact it's possible to load uImage from TFTP server and bootm it. 4. Minor fixes for HSDK clocks. 5. Rework of how we chose and use compiler options for ARC-based boards. In real world ARC-based designs are customized more or less but very rarely match any of our "templates" thus it makes not much sense to pretend we have some fixed configs, instead we now will fully reply on a SoC or even board on getting precise set of compiler options preferably even extracted from real HW via "tcfgen" utility. 6. Well and finally yet another simplification - switch to generic written in C accessors which are much more universal and just work for any target supported by the complier as compared to GAS implementation which is much more target-dependent. This one was heavily "inspired" by similar implementation for RISCV and ARM. [1] https://www.synopsys.com/cgi-bin/dwarcnsim/req1.cgi

arc-fixes-for-2020.07-rc1
This is pretty minor set of changes mostly touching HSDK board: * Enable on-chip reset controller on HSDK * Add possibility to turn-on & off L2$ on more recent ARC HS processors. * AXI tunnel clock calculation on HSDK

arc-fixes-for-2020.07-rc3
Here we improve clock support for recently introduced HSDK-4xD board as well as finally enable external reset for the USB controller, which is needed to recover USB functionality after "usb reset".

arc-for-2018.05
More ARC changes and fixes for v2018.05 * Update of ARC tools to the most recent arc-2017.09 * Fix for compile-time warning for AXS10x * Add support of platform-specific commands for HSDK * Add support for on-board SPI flash on HSDK Note though that for write support another series [1] is required. I hope that Jagan will be able to review and act on SPI flash improvement series before we get beyond RC1. Also note that to get clean build for HSDK we need to disable stack-usage check [2] as our current GCC erroneously tries to calculate stack-usage on a naked function which leads to warning.

arc-for-2018.05-rc3
Subtle ARC fixes for v2018.05-RC3 These are only very subtle clean-ups here and there including: * Correctly specified CPU freq for HSDK (production boards are all shipped with 500MHZ as opposed to early batch running at 1GHz) * Addition of SNPS internal group email to MAINTAINERS file * Switch to Hush shell on AXS10x boards

arc-for-2018.11
Just 2 non-functinal changes: 1. Rename of EMDK to EMSDP so it matches real marketing name 2. Add essential README for IoTDK
-
arc-for-2019.07
In this small series we migrate ARC boards to DM_MMC so we're hopefully are good now and our boards will be kept in U-Boot for some more time :)
-
arc-for-2019.10-rc4
These are some very late changes mostly required to get 64-bit division working on ARC boards. For that we had to import missing parts of libgcc and add compiler flags to EMSDP which otherwise used very simple profile for compliation. And while at it another fix for EM SDP initialization is inluded as well.

arc-for-2022.07
ARC fixes for 2022.07 A minor build fix for HSDK, kudos to Corentin Labbe.
