Hello Hans,

I am looking for bit of advice on how to handle these errors I see in 
the dmesg print , it starts here :

[    0.077227] pinctrl core: initialized pinctrl subsystem
[    0.079533] NET: Registered protocol family 16
[    0.080837] DMA: preallocated 256 KiB pool for atomic coherent 
allocations
[    0.094301] No ATAGs?
[    0.094369] hw-breakpoint: found 5 (+1 reserved) breakpoint and 4 
watchpoint registers.
[    0.094438] hw-breakpoint: maximum watchpoint size is 8 bytes.

and then continues with this bit a little later :

[    4.303004] gmac-3v3: disabling

I have been compiling my own kernels from Fedora src rpms due to the 
need to add in the 'b53' switch drivers . I have just used standard 
Fedora CONFIGs with addition of

CONFIG_PHY_SUN4I_USB=y
CONFIG_MFD_AXP20X=y
CONFIG_AXP20X_POWER=y
CONFIG_INPUT_AXP20X_PEK=y
CONFIG_REGULATOR_AXP20X=y

But this did not seem to make any difference . Is there something that I 
am missing out in config , or a patch somewhere in the dts ?

Any information welcomed .

Best Regards
