* [U-Boot] [PATCH 01/10] ARM: Rename arch/arm/cpu/arm_cortexa8 to armv7
2010-06-15 4:39 [U-Boot] [PATCH 00/10] Add support for TI OMAP4 SDP and Panda Steve Sakoman

To: u-boot
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.

Once the declaration in /board/ti/sdp4430/sdp.c is made global this won't be
needed.

It still seems to be needed to avoid a compile time error, even with
the global declaration
in /board/ti/sdp4430/sdp.c.

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

From: Steve Sakoman @ 2010-06-15 4:39 UTC (permalink / raw)
To: u-boot
OMAP4 Panda 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

This seems identical to me to the defines in
arch/arm/include/asm/arch-omap24xx/i2c.h and
arch/arm/include/asm/arch-omap3/i2c.h
Instead of making here a third copy of this defines, we
should make a common omap i2c.h file, which collects all
common defines, and only add in this file here the
specific defines.
This applies to a lot of defines below. Please
clean up, thanks!

Thanks for the comments. I made the changes and I'm preparing a
version 2 patch.
A quick procedure question. Should I post individual version 2 patch
replies for each patch in the series that has received comments, or is
it preferred to post a complete version 2 series? I see both
approaches used on the list so I'm a bit confused which is proper.

I have no preference, both seems Ok to me. Say you have to make
for some patches a version 2, 3, 4 and they fit together with
lower versions from other patches from your patch series, it is
okay to post only individual versions, but the complexity can grow,
mainline code changes, so it could make sense to post the complete
patch series again.

I have no omap4 hw yet so I can't test this but I have build-tested this

still works on Beagle.
