Subject: [PATCH] MIPS: Calculate VMLINUZ_LOAD_ADDRESS based on the length of vmlinux.bin
Date: Tue, 31 Aug 2010 13:24:19 +0300	[thread overview]
Message-ID: <4c7cd856.cb71df0a.1986.ffffad0f@mx.google.com> (raw)

Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of vmlinux.bin,
the actual uncompressed kernel binary.

Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF
vmlinux), which is bigger than vmlinux.bin.
As a result, vmlinuz was loaded into a memory address higher then actually
needed - a problem for small memory platforms.
