* arc770/axs101: fix console outputFelix Fietkau2016-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While bumping kernel version kernel command line was unintentionally modified in attempt to make it closer to upstream version. In case of AXS that has not only serial port but HDMI/USB both capable of being debug console we have 2 entries in kernel's command line: ------------------->8----------------- console=tty0 console=ttyS3,115200n8 ------------------->8----------------- But as it turned out OpenWRT uses procd as init instead of Busybox. And in its turn procd gets the first "console" entry from kernel command line (/proc/cmdline) and uses it if default inittab is used: ------------------->8----------------- ... ::askconsole:/bin/ash --login ------------------->8----------------- So what we got is non-functional serial console. That change removes "console=tty0" which brings serial console back to life.

* arc770: bump linux kernel from 4.3 to 4.4Felix Fietkau2016-01-154-3/+4
| | | | | | | | | | | | | | | | This switch involved: [1] Regeneration of config (few options went away) [2] Regeneration of patches so they apply cleanly (different offsets) [3] Update of .dts files because we now explicitly specify memory regions in use as opposed to previously used offset from 0x8000_0000 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Felix Fietkau <nbd@openwrt.org> Cc: Jo-Philipp Wich <jow@openwrt.org> Cc: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 48240
* linux: add support of Synopsys ARC770-based boardsFelix Fietkau2015-11-225-0/+454
This patch introduces support of new boards with ARC cores. [1] Synopsys SDP board This is a new-generation development board from Synopsys that consists of base-board and CPU tile-board (which might have a real ASIC or FPGA with CPU image). It sports a lot of DesignWare peripherals like GMAC, USB, SPI, I2C etc and is intended to be used for early development of ARC-based products. [2] nSIM This is a virtual board implemented in Synopsys proprietary software simulator (even though available for free for open source community). This board has only serial port as a peripheral and so it is meant to be used for runtime testing which is especially useful during bring-up of new tools and platforms. What's also important ARC cores are very configurable so there're many variations of options like cache sizes, their line lengths, additional hardware blocks like multipliers, dividers etc. And this board could be used to make sure built software still runs on different HW configurations.
