From 3ea744e87359f95251ae7ec3c7a92f8b3293593b Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Tue, 22 Mar 2022 16:59:23 -0400 Subject: arm: smh: Add some functions for working with the host console This adds three wrappers around the semihosting commands for reading and writing to the host console. We use the more standard getc/putc/puts names instead of readc/writec/write0 for familiarity.
