Subject: [PATCH] ARM: Add relocatable binary support
Date: Mon,  4 Mar 2013 21:03:03 +0100	[thread overview]
Message-ID: <1362427389-2144-1-git-send-email-s.hauer@pengutronix.de> (raw)

The following adds relocatable binary support for ARM. This can
be useful when a suitable memory location for the barebox binary
is not known at compile time, for example when compiling for multiple
SoCs.

In most cases enabling this feature will only result in the visible
effect that the binary gets bigger, so this feature is fully optional.
The relocatable support can be enabled for the PBL and the real binary
independently for greater flexibility and better debugability.

This series has been tested on various boards and I hope I have
covered all combinations of PBL enabled/disabled, PBL relocation
enabled/disabled, relocation enabled/disabled and MMU enabled/disabled.
