Nothing has changed between postings. I resent same patch because during 
first posting of this patch I got message as below:

[U-Boot] [PATCH] da830: add MMC support
Is being held until the list moderator can review it for approval.

Apologize, If you got two versions of same patch. Please ignore first
version and consider this patch for review.

[U-Boot] i2c loop command

[TigerLiu at viatech.com.cn]

Hi, experts:
There is an iloop command in older version uboot.
Current uboot also included "i2c loop" cmd.
It's an infinite loop on i2c_read.

So, when to use this command?
Just for debugging I2C read function?

Best wishes,

[U-Boot] i2c loop command

Yes.

Yes!

> So, when to use this command?

If you want to read in a loop from an i2c chip addr ... It is in the
first place for debugging purposes.

bye,
Heiko

OK, thanks.  The first copy was approved by the moderators :)  I should
pick this up for the TI tree soon.
