it must have been lost in the copy and paste I will fix it.

As you probably know, a lot of "magical" initialization is done in the
U-boot from Marvell. So maybe is it the reason why u-boot was mentioned.
However you're right I will ask more information about especially if it
is safe to have this value with an older u-boot.

Thanks,

Gregory
