Hi all,
Some resources related work in this series:
- add missing IORESOURCE_MEM flag to resources created by the
wrapper in register_device
- add helper to register memory devices
- drop struct memory_platform_data
- switch all of the memory to new helper
- get rid of some map_base in the core
- convert the majority of i.MX devices to struct resource
The following changes since commit 7530c82c3d295c2e93f440dc2ee6440a72e41c3a:
startup.c: make DEBUG_LL output more useful (2011-07-18 23:04:18 +0200)
are available in the git repository at:
git://uboot.jcrosoft.org/barebox.git resource

We might want to add real resource tracking later. Also
The first resource may not be a IORESOURCE_MEM at all.
For these reasons introduce a wrapper function for
driver so that they do not have to fiddle with resources
directly.

To: barebox
From: Sascha Hauer <s.hauer@pengutronix.de>
Add a helper function for boards to register their memory
devices. This makes the board code smaller and also helps
getting rid of map_base and struct memory_platform_data.
And switch all of the memory to it

This is the non invasive approach. All this type casting
shows this driver should be really cleaned up (or retired)

From: Sascha Hauer <s.hauer@pengutronix.de>
Add a helper function for boards to register their memory
devices. This makes the board code smaller and also helps
getting rid of map_base and struct memory_platform_data.
And switch all of the memory to it
