[U-Boot] [PATCH 0/4 v2] AM35X: Add musb support

[U-Boot] [PATCH 0/4 v2] AM35X: Add musb support

[Ajay Kumar Gupta]

Remy,

These patches add support for musb in AM35x.
Changes from v1:
	- Moved SCM definitions to am35x specific file am35x_def.h

Patches have been created against uboot-ti/master tree (as on 9th July)
but they also apply cleanly to both denx/master and uboot-usb/master
as there is no interdependent changes.

Regards,
Ajay

[U-Boot] [PATCH 1/4 v2] AM35x: Adding SCM general register definitions

[Ajay Kumar Gupta]

Adding general register structure of system control module (SCM)
of AM35x. This would be required to access devconf2 and ip_sw_reset
register in musb module.

You ACK these? I would expect they go in through the USB repository.
What is your expectation - who should apply these patches? 

Best regards,

I guess I was not fully awake when I sent that, I thought it was part
of a bigger series that should go in the u-boot-ti tree...
Anyway, I applied it to the u-boot-usb tree already a week ago...

Kind regards,

Remy
