[U-Boot] [PATCH] DEBUG 8xxx cpu_numcores

[Ed Swarthout]

The following debug patch shows that gd->cpu is not being relocated to
ddr.  Linux may not be able to boot due to "fdt board" crashing if
flash has been erased or changed.

On mpc8572ds:

=> fdt board
fdt board
cpu_numcores gd=3fe6df68 cpu=effed578 n=2
cpu_numcores gd=3fe6df68 cpu=effed578 n=2
cpu_numcores gd=3fe6df68 cpu=effed578 n=2
cpu_numcores gd=3fe6df68 cpu=effed578 n=2
