From d5f3d17ca6b6272d9096912579778b67fa40a164 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 23 Mar 2015 11:06:13 +0100 Subject: [PATCH] armv8: semihosting: delete external interface Now that loading files using semihosting can be done using a command in standard scripts, and we have rewritten the boardfile and added it to the Vexpress64, let's delete the external interface to the semihosting file retrieveal and rely solely on these commands, and staticize them inside that file so the whole business is self-contained.
