-Subject: [PATCH 1/1] bios: Don't try to guess the sections alignment
-
-For the compression / decompression to succeed, the sections layout must
-be the same between the virtual memory and load memory. The section
-alignment was kept in sync by introducing aligment that should be
-greater or equal to the actual section alignment.
-
-This patch compute the load memory addresses of the sections so that
-the layout is the same as the virtual memory addresses.
