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
