From 67482f57e6127d7d3e216dae6860dac7b33132d5 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Fri, 25 Nov 2016 16:23:43 +0300 Subject: arc: Add support for HS Development Kit board ARC HS Development Kit board is a new low-cost development platform sporting ARC HS38 in real silicon with nice set of features such as: * Quad-core ARC HS38 with 512 kB L2 cache and running @1GHz * 4Gb of DDR (we use only lowest 1Gb out of it now) * Lots of DesigWare peripherals * Different connectivity modules: - Synopsys HAPS HT3 - Arduino-compatible connector - MikroBUS This initial commit supports the following peripherals: * UART (DW 8250) * Ethernet (DW GMAC) * SD/MMC (DW Mobile Storage) * USB 1.1 & 2.0 Signed-off-by: Alexey Brodkin --- arch/arc/Kconfig | 4 ++++ arch/arc/dts/Makefile | 1 + arch/arc/dts/hsdk.dts | 50 ++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 55 insertions(+) create mode 100644 arch/arc/dts/hsdk.dts (limited to 'arch/arc') diff --git a/arch/arc/Kconfig b/arch/arc/Kconfig index 6e4b1d0..e3f9db7 100644 --- a/arch/arc/Kconfig +++ b/arch/arc/Kconfig @@ -132,10 +132,14 @@ config TARGET_AXS101 config TARGET_AXS103 bool "Support Synopsys Designware SDP board AXS103" +config TARGET_HSDK + bool "Support Synpsys HS DevelopmentKit board" + endchoice source "board/abilis/tb100/Kconfig" source "board/synopsys/Kconfig" source "board/synopsys/axs10x/Kconfig" +source "board/synopsys/hsdk/Kconfig" endmenu diff --git a/arch/arc/dts/Makefile b/arch/arc/dts/Makefile index 218a647..63a6694 100644 --- a/arch/arc/dts/Makefile +++ b/arch/arc/dts/Makefile @@ -6,6 +6,7 @@ dtb-$(CONFIG_TARGET_AXS101) += axs101.dtb dtb-$(CONFIG_TARGET_AXS103) += axs103.dtb dtb-$(CONFIG_TARGET_NSIM) += nsim.dtb dtb-$(CONFIG_TARGET_TB100) += abilis_tb100.dtb +dtb-$(CONFIG_TARGET_HSDK) += hsdk.dtb targets += $(dtb-y) diff --git a/arch/arc/dts/hsdk.dts b/arch/arc/dts/hsdk.dts new file mode 100644 index 0000000..a7b276c --- /dev/null +++ b/arch/arc/dts/hsdk.dts @@ -0,0 +1,50 @@ +/* + * Copyright (C) 2017 Synopsys, Inc.
