From eaac4fb296b1899369e49d941f2c0d346c7f5c7a Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 26 Sep 2018 14:07:41 +0200 Subject: [PATCH] sandbox: Fix set_working_fdt_addr users When running sandbox with the new pointer sanitization we just recently introduced, we're running into a case with FIT images where we end up interpreting pointers as addresses. What happened is that most callers of set_working_fdt_addr() simply convert pointers into addresses without taking into account that they might be 2 separate address spaces. Fix the callers up to map their pointers into addresses. This makes sandbox tests pass for me again.
