Note: I am taking over patch submission for OMAP4 from Aneesh.
This is version 3, which takes into account all feedback to date, and has
been rebased on the next branch.
The folowing series adds support for two boards based upon the TI
OMAP4430. The OMAP4430 is a Cortex-A9 based SOC from TI.
The first patch in this series renames the cpu arm_cortexa8 to armv7 so
that the existing cortex A8 code can be shared with cortex A9. Both A8 and
A9 are based on ARMV7 architecture.
The 2nd patch adds basic OMAP4 architecture support.
The 3rd and 4th patches add minimal board support for the Panda and SDP.
The 5th patch restructures the OMAP mmc driver code so that it can be
shared by both OMAP3 and OMAP4 boards. This patch depends on a previously
submitted patch (OMAP: mmc: add support for second and third mmc channel):
http://www.mail-archive.com/u-boot at lists.denx.de/msg31765.html
The 6th and 7th patches add mmc support for Panda and SDP.
The 8th patch restructures the OMAP i2c code so that it can be shared by
both OMAP3 and OMAP4 boards.
And, finally, the 9th and 10th patches add i2c support for Panda and SDP.

The purpose of this patch is to prepare for adding the OMAP4 architecture, which is Cortex A9
Cortex A8 and A9 both belong to the armv7 architecture, hence the name change.
The two architectures are similar enough that substantial code can be shared.

OMAP4430 SDP is a reference board based on OMAP4430, an ARMV7 Cortex A9 CPU
This patch adds minimum support for booting the board. It assumes U-boot
is loaded to SDRAM with the help of another small bootloader (x-load)
running from SRAM. U-boot currently relies on x-load for clock, mux, and
SDRAM initialization

It'd be preferred if you could reorganize the patch series to first make
all CPU/SOC changes, then finally do 1 patch for each board. This is
generally considered cleaner than having patches bouncing back and forth
between common and board specific code. Right now the SDP and Panda
boards each require 3 patches when 1 patch apiece should suffice. eg:
ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
ARMV7: Add basic support for TI OMAP4
ARMV7: Restructure OMAP mmc driver to allow code sharing between OMAP3 and OMAP4
ARMV7: Restructure OMAP i2c driver to allow code sharing between OMAP3 and OMAP4
ARMV7: Add support for TI OMAP4430 SDP
ARMV7: Add support for TI OMAP4 Panda
Best,
Peter

In the past I've had complaints that I should break each piece of
functionality into a separate patch :-)
I'm happy to do whatever is preferred! Wolfgang, would you like a v4
with the proposed structure?
Regards,
Steve

Well, the rules are formulated as clear as I could (improvments always
welcome!) - please see "General Patch Submission Rules" bullet # 2 at
http://www.denx.de/wiki/U-Boot/Patches

Yes, please. Peter is absolutely right. And please keep in mind that
at each step in your patch series the code must be buildable and
runnable, so we can use git bisect to isolate problems.
Best regards,
Wolfgang Denk

In the beginning there was nothing.
And the Lord said "Let There Be Light!"
And still there was nothing, but at least now you could see it.

OK, will do. Version 4 will be on the way shortly!
