[U-Boot] [PATCH][MPC8272ADS]

[Jean-Michel Hautbois]

When trying to compile and boot from u-boot (after make distclean ;
make MPC8272ADS_config ; make), I had these three errors:

Loading Device Tree to 007fb000, end 007ff159 ... OK
Unable to update property /cpus/cpu at 0:bus-frequency, err=FDT_ERR_NOTFOUND
Unable to update property /cpus/cpu at 0:timebase-frequency, err=FDT_ERR_NOTFOUND
Unable to update property /cpus/cpu at 0:clock-frequency, err=FDT_ERR_NOTFOUND

When looking at the include/configs/MPC8260ADS.h file, the OF_CPU was
set to "cpu at 0".
In the linux kernel, the dts file in
arch/powerpc/boot/dts/mpc8272ads.dts contains "PowerPC,8272 at 0".

Here is the little patch I am proposing in order to correct this issue
for the MPC8272ADS board.

Best Regards.
JM
