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
