Adding this too to devel-am33xx branch. Thanks Tony, Also, request you to add it as part of next pull request to the linux-next, at early rc cycle itself. Paul, Can you also send a pull request for AM33XX voltagedomain, cm, clockdomain, prm, powerdomain patches? Also request you to review clock-tree and hwmod changes, so that, they can also be merged within time. From clocktree perspective, I believe now I have to migrate to Rajendr's common-clock framework changes, so let me finish that and send new version.

[PATCH] ARM: OMAP2+: am33xx: Add AM335XEVM machine support
From: Afzal Mohammed af...@ti.com
This patch adds minimal support for AM335X machine init.
During last merge window, two separate patches supporting am33xx
machine init had been submitted,
1. Link to earlier Baseport patch submission (Legacy):
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg59325.html
2. Link to earlier DT based machine init support patch submission:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg61398.html
And both had got accepted at that time, but got missed during
merge window.
But now, since we have taken decision to make am33xx as a separate
class and not to follow omap3 family, these patches needs to changes
accordingly (only changes),
- Combine both the patches, since early init and timer init
used in board-generic.c file requires them.
- Remove dependency on AM3517EVM, and only use DT approach
for machine init.
- Change the config option (as changed recently)
