[PATCH 0/3 v8] hsdk: initial port for HSDK board

This series introduces some required preparations and initial port of ARC HS Development Kit board with some basic features such as serial port, USB, SD/MMC and Ethernet. Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) and heavily use IO Coherency for speeding-up DMA-aware periph

[PATCH 3/3] ARC: hsdk: initial port for HSDK board

From: Alexey Brodkin This initial port adds support of ARC HS Development Kit board with some basic features such serial port, USB, SD/MMC and Ethernet. Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) and heavily use IO Coherency for speeding-up DMA-aware peripherals. Note as

[PATCH 1/3] ARC: Set IO-coherency aperture base to LINUX_LINK_BASE

Most of the time we indeed use the one and only LINUX_LINK_BASE set to 0x8000_. But there might be good reasons to move the kernel to another location like 0x9z etc. And we want IOC aperture to cover entire area used by the kernel, so let's make its base matching link base and add required ass

[PATCH 2/3] ARC: Decouple linux kernel memory address and link address

We faced with problem when we tried to utilize 1G DRAM by linux on HSDK. We can't use our usual kernel memory address (0x8000) like on AXS103 because of DCCM memory bank located at exactly same address (0x8000) But we can't simply move kernel memory address to another address (like 0x9

[PATCH] earlycon: initialise baud field of earlycon device structure

For now baud field of earlycon structure device is't initialised at all in of_setup_earlycon (in oppositе to register_earlycon). So when I use stdout-path to point earlycon device (like stdout-path = &serial or stdout-path = "serial:115200n8") baud field of earlycon device structure remains uninit

[PATCH] hsdk: Enable INPUT_EVDEV

This is required for user-space apps to work with keyboard/mice. Signed-off-by: Alexey Brodkin Cc: Eugeniy Paltsev --- arch/arc/configs/hsdk_defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arc/configs/hsdk_defconfig b/arch/arc/configs/hsdk_defconfig index f4190bcde594..b3d212
