From 9515e41d38cc81046c9bc5c766552ce5e278b263 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 26 Dec 2019 13:46:27 +0300 Subject: ARC: nSIM: switch from ARC UART to DW UART Since v2019.06 DesingWare nSIM supports DesignWare UART simulation and so we may switch from pretty unusual ARC UART to much more standard DesignWare UART (which in case of U-Boot is just an ordinary 16650 UART). This among other things makes built dinaries compatible with our other platforms to name a few: FPGA-based HAPS boards, QEMU and even ZeBU.
