OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP
architecture. It's a dual core SOC with GIC used for interrupt
handling and with an integrated L2 cache controller.

OMAP5432 is another variant of OMAP5430, with a
memory controller supporting DDR3 and SATA.

Patch includes:
 - The machine specific headers and sources updates.
 - Platform header updates.
 - Minimum initialisation support for serial.
 - IO table init

I am not sure whether we had discussed on this before, couldn't find it.

Why don't we reuse OMAP4 data here and elsewhere??

This is conflicting with AM33XX, you may want to rebase it again, since
AM33xx clock tree is already pushed and available in
linux-omap/devel-am33xx-part2.

We have mix of such definitions here, for example,

"arch/arm/plat-omap/include/plat/sram.h"
and now in arch/arm/plat-omap/sram.c here itself.


May be right time to clean it up now.

Because data is not same between OMAP4 and OMAP5.
Wherever it is same, it is taken care.

Thats because of an interconnect BUG which needed it exported
at plat level in case of OMAP4.

Above most of the base-addresses are same as omap4.

And what about clocktree and hwmod? Is it going tobe same as omap4? 
Or we have separate data generated?

Not only omap4, but we have 2, 3, 4 and AM33xx definitions present there
at plat/sram.h and public PA (SRAM_PUB_PA) address is defined in sram.c file.

The data generated is different for OMAP5. Hwmod, powerdomain, clockdomain,
muxes. This data is out of the tree now since we are waiting for ES2.0
data which
has some differences w.r.t ES1.0. This was discussed in the beginning
as part of this
series review on the list.

I see that now. Infact there is no need for any of those PA's to be defined
there except OMAP4 which needs to have that macro available for an errata.

I will clean that up once the series is merged. Don't want to introduce any
regression in last moment changes.

Ok, this is useful information.

My bad, I missed that discussion, and will refer to archives now.
