* arc770: enable unaligned access handling simulation in softwareJohn Crispin2016-04-091-2/+3
| | | | | | | | | | | | This enables misaligned access handling by software in Linux kernel. With some wireless drivers (ath9k-htc and mt7601u for example) we see misaligned accesses here and there and to cope with that without fixing stuff in the drivers we're just gracefully handling it on ARC.

* arc770: build kmod-ath9k-htc wpad-mini by defaultJohn Crispin2016-04-092-2/+2
| | | | | | | | | | | | | | | | AXS101 beind a development board lacks built-in wireles inerfaces. So we have to use external USB dongles to turn the board into wireless router. The best USB Wi-Fi dongles to work in AP-mode seem to be based on ath9k-htc chipset. And so with that change we add support of mentioned dongles in default and axs101 builds.

* arc: clean-up and move CFLAGS to include/target.mkFelix Fietkau2016-01-181-1/+0
| | | | | | | | | | | | | | | | | | | Most of currently mentioned CFLAGS in arc770/Makefile are not really required because: [1] "-Os -pipe" are set by default in include/target.mk [2] "-fno-caller-saves" gets enabled via menuconfig as an extra compiler flag for developers So the only one that makes sense is "-matomic" and that one is really essential. Without it many software packges won't build complainin on unresolved atomic ops.

* 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: move arc patches to target/linux/genericFelix Fietkau2016-01-152-127/+0
| | | | | | | | | | | | | | | | Given those patches are relevant to any ARC platform and even ISA version it makes perfect sense for patches to exist in one place instead of being duplicated for each new ARC-based ASIC. Note this is a prerequisite for upstreaming of ARC HS38 support in OpenWRT.

* arc770: bump linux kernel from 4.3 to 4.4Felix Fietkau2016-01-158-25/+30
| | | | | | | | | | | | | | | | 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 Fietkau2015-11-2219-0/+981
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.
