OMAP4460 is the latest addition to the OMAP4 family.
OMAP4460 has dual core Cortex-A9 CPUs that can be clocked upto
1.5 GHz
The memory architecture has been improved to provide better
performance and there several other minor improvements in various
modules.
Aneesh V (5):
omap4: add omap4460 revision detection
omap4: sdram init changes for omap4460
omap: reuse omap3 gpio support in omap4
omap4: support TPS programming
omap4: clock init support for omap4460

TPS62361 is the new power supply used in OMAP4460 that
supplies vdd_mpu.
VCORE1 from Phoenix supplies vdd_core and VCORE2 supplies
vdd_iva. VCORE3 is not used in OMAP4460.

Oops! That is a script mishap. I have a couple of convenience scripts
(wrappers over git format-patch). Used the wrong one here. I didn't
notice it until now.

Forgot to mention that this series depends on the OMAP4 spl series [1]
and the SPL framework series [2]

OMAP4460 is the latest addition to the OMAP4 family.
OMAP4460 has dual core Cortex-A9 CPUs that can be clocked upto
1.5 GHz
The memory architecture has been improved to provide better
performance and there several other minor improvements in various
modules.
This series depends on the OMAP4 spl series [1] and the SPL framework
series [2]
[1] http://marc.info/?l=u-boot&m=131082102506002&w=2
[2] http://marc.info/?l=u-boot&m=131056990001719&w=2
Changes in V2:
* Added missing file in the patch 3/5
* Corrected subject lines of patches
Aneesh V (5):
omap4: add omap4460 revision detection
omap4: sdram init changes for omap4460
omap: reuse omap3 gpio support in omap4
omap4: support TPS programming
omap4: clock init support for omap4460

From: Aneesh V @ 2011-07-20 10:55 UTC (permalink / raw)
To: u-boot
TPS62361 is the new power supply used in OMAP4460 that
supplies vdd_mpu.
VCORE1 from Phoenix supplies vdd_core and VCORE2 supplies
vdd_iva. VCORE3 is not used in OMAP4460.

Wolfgang, Albert,
If it is OK with you I'd like to pull in all the 3 patch sets into u-boot-ti.
This would also include the patch set to update the SPL framework.
Regards,
Sandeep

There is a v3 version of the SPL framework series.
You are pointing to the RFC series.
I hope your patches are based on the v3 patch series of the SPL framework.

I just realized that this change in header file name was breaking some
omap3 boards. I had tested only omap3_sdp3430. But some other boards
used GPIO functions in the board layer, which I didn't notice.
I will send out a patch shortly to fix this.
