Subject: [PATCH 2/2] arm: Clean up linker script using new linker script macros.
From: Nelson Elhage <nelhage@...lice.com>
This patch is mostly a straightforward translation. The primary side
effect to the resulting vmlinux should be to increase the alignment on
the initramfs to the standard PAGE_SIZE from 32 bytes.
