From 34cc1a8fe0d3f89f3602b49f1121a99d2bfc5efc Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Tue, 19 Apr 2011 15:42:43 -0400 Subject: ARM: zImage: no need to get the decompressed size from the filesystem In commit d239b1dc093d the hardcoded 4x estimate for the decompressed kernel size was replaced by the exact Image file size and passed to the linker as a symbol value. Turns out that this is unneeded as the size is already included at the end of the compressed piggy data. For those compressed formats that don't include this data, the build system already takes care of appending it using size_append in scripts/Makefile.lib. So let's use that instead.
