This patch series is submitted to add support for MMC/SD along
with SPL support. Also, fixed incorrect register offset of
ddr and timer registers.

The patches have been compile tested and run on AM335X EVM.

The patches depends on previous patch series which was submitted
for supporting AM33xx platform.

The patches are applies on uboot v2011.09 baseline.

Chandan Nath (3):
  ARM:AM33XX: Fix ddr and timer register offset
  ARM:AM33XX: Add mmc/sd support
  ARM:AM33XX: Add SPL support for AM335X EVM

This patch is added to update incorrect ddr, pll and timer
register offset along with some additional cleanup like
removing unused code. Also, generic CONFIG_AM33XX symbol
is added for AM33XX platform.

The omap_hsmmc.c part isn't needed (I had added that when playing with
an idea and didn't remove from the WIP patch I sent you).

Note that the intention is that CONFIG_AM335X goes away (and we can
evaluate the right symbol breakdown once a non am335x am33xx part
arrives.

Please see the Overo SPL thread where Wolfgang mentions the right way
to init this to 0 and have it be in the data section, followed by me
saying I'd see if <linux/compiler.h> had a shortcut.

Something I wanted to see, but hadn't had a chance to look into was if
we could use the OMAP4/5 code for boot_mode as well, can you please
check?

Not that it's a huge deal but you didn't update lowlevel_init.S to not
pass in a param when calling s_init.

Stuff either belongs in arch-am33xx/sys_proto.h or we need to re-think
where we're going with the pinmux code.  I know things will get more
complicated once we add i2c and can detect board revs and all of that.

In the future please send things vs either top of tree mainline or top
of tree u-boot/next, depending on what's required (in this case, just
top of tree mainline would be fine).  The defines for which boot
devices aren't at all what I sent you along (which tries to make this
a bit less of a mess for whatever comes along next) because 2011.09
doesn't have OMAP5.  Thanks.

But here looks like he doesn't intend to initialize it to 0?

OMAP4/5 code parses ROM code structures (using a pointer passed by ROM
code). If those structures and their layout are exactly same in AM33XX,
it may work, otherwise it won't.

I intended to before going "oh, that's right, it ends up in the BSS
not the data section, lemme set it to a value".

Yes, I think we share enough ROM code that it should work.  We're
using the OMAP4/5 code for boot device already (and it works for a
number of modes, we just don't have all the supporting code in
submittable state).
