From: Alexey Brodkin Date: Thu, 4 Aug 2016 11:35:01 +0000 (+0300) Subject: arc: Rename ARCangel4 board to nSIM X-Git-Tag: v2016.09-rc2~134 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=cc8be222d1cf37c4299c019b95d7d932f2a4bbcc;p=oweals%2Fu-boot.git arc: Rename ARCangel4 board to nSIM ARCangel was one of the main development boards back in the day but now it's gone and replaced by other boards like ARC SDP. But we also used to have simulation platform very similar to ARCangel4 in terms of CPU settings as well as basic IO like UART. Even though ARCangel4 is long gone now we have a replacement for simulation which is a plain or stand-alone nSIM and Free nSIM. Note Free nSIM is available for download here: https://www.synopsys.com/cgi-bin/dwarcnsim/req1.cgi And while at it: * Finally switch hex numerical values in nsim.h to defines from include/linux/sizes.h * Add defconfigs with ARC HS38 cores * Recreated all defconfigs with savedefconfig Signed-off-by: Alexey Brodkin --- diff --git a/arch/arc/Kconfig b/arch/arc/Kconfig index f1dc6c8d77..b81d0ca3c3 100644 --- a/arch/arc/Kconfig +++ b/arch/arc/Kconfig @@ -123,8 +123,8 @@ choice config TARGET_TB100 bool "Support tb100" -config TARGET_ARCANGEL4 - bool "Support arcangel4" +config TARGET_NSIM + bool "Support standalone nSIM & Free nSIM" config TARGET_AXS101 bool "Support axs101" diff --git a/arch/arc/dts/Makefile b/arch/arc/dts/Makefile index d4772ecabb..196f882963 100644 --- a/arch/arc/dts/Makefile +++ b/arch/arc/dts/Makefile @@ -3,7 +3,7 @@ # dtb-$(CONFIG_TARGET_AXS101) += axs10x.dtb -dtb-$(CONFIG_TARGET_ARCANGEL4) += arcangel4.dtb +dtb-$(CONFIG_TARGET_NSIM) += nsim.dtb dtb-$(CONFIG_TARGET_TB100) += abilis_tb100.dtb targets += $(dtb-y) diff --git a/arch/arc/dts/arcangel4.dts b/arch/arc/dts/arcangel4.dts deleted file mode 100644 index bfcb9d8369..0000000000 --- a/arch/arc/dts/arcangel4.dts +++ /dev/null @@ -1,24 +0,0 @@ -/* - * Copyright (C) 2015 Synopsys, Inc.
