From f1467d4b0014256a4405f97beb3ca46246fa1967 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Tue, 20 Sep 2016 20:31:32 +1200 Subject: nativesdk-qemu-helper: drop old Zaurus flash tools These tools are relics of an earlier time when the Zaurus devices were reference platforms - these days they are no longer needed. It seems amazing that they survived earlier purges.
