[PATCH] of: export of_platform_populate()

From: Stephen Warren <swarren@nvidia.com>

Without this, modules can't use this API, leading to build failures.

This is useful in 3.5.

Booting MX28-EVK without bootloader support

[Subodh Nijsure]

I am using git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git 
for-next branch to get familiar with device tree.

I am following procedure described in following thread --

http://lists.ozlabs.org/pipermail/devicetree-discuss/2012-April/014600.html

Turn on CONFIG_ARM_APPENDED_DTB,  CONFIG_ARM_ARAG_DTB, then appending 
imx28-evk.dtb and constructing zImage_dtb

However this image never initializes network interfaces, I can't mount 
nfs as rootfs. Is the appended DTB supposed to work from above 
referenced git repo & branch?

Is there a device-tree newbies mailing list by any chance?

Pardon me, if this is too basic DT question on device tree 
initialization sequence. During initialization I see that - 
mxs_machine_init gets called which invokes of_platform_populate(). 
However I don't see the mx28evk_init() function never gets called, 
should that function be getting called?

If mx28evk_init shouldn't be called how is MXS ethernet driver supposed 
to get registered when using device tree?

Applied for 3.5.

Thanks.

Do you know when it will show up in linux-next and/or 3.5 itself? The
patch hasn't rebased out of my local tree yet.

Unless I missed it, Grant has not yet pulled my pull request with this.
I'm just the maillist patch monkey. :)
