Again this default stuff? ;)
I should have replied to your previous comment.
I tried removing this block as you suggest and the board does not boot.
Then I read the following from the FSL U-boot: "/* Enable all clocks (they are disabled by ROM code)*/
That's why I am keeping them.
Most probably it would be sufficient to enable only the clocks needed for booting ;) And not all clocks. On the other boards we do
/* set the default clock gate to save power */ DATA 4 0x020c4068 0x00C03F3F DATA 4 0x020c406c 0x0030FC03 DATA 4 0x020c4070 0x0FFFC000 DATA 4 0x020c4074 0x3FF00000 DATA 4 0x020c4078 0x00FFF300 DATA 4 0x020c407c 0x0F0000C3 DATA 4 0x020c4080 0x000003FF

Do you like to try anything similar here, too?
Best regards
