This pointer needs to be updated to point to an address in RAM after relocation has occurred otherwise Linux may not be able to boot due to "fdt board" crashing if flash has been erased or changed.

The gd->cpu pointer is set to an address located in flash when the
probecpu() function is called while U-Boot is executing from flash.
This pointer needs to be updated to point to an address in RAM after
relocation has occurred otherwise Linux may not be able to boot due to
"fdt board" crashing if flash has been erased or changed.

mpc85xx: Fix booting on various boards 2009-10-16T15:21:56+00:00 Anton Vorontsov avorontsov@ru.mvista.com 2009-10-12T19:55:39+00:00 91525c67153fcf2c19b2fc8d9c6376ac1a019f52 commit 0e870980a64584a591af775bb9c9fe9450124df9 ("8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx") breaks U-Boot on various boards, namely the ones that call get_sys_info() from board_early_init_f(). get_sys_info() calls cpu_numcores(), which depends on probecpu() being called before. But probecpu() is called after board_early_init_f(), and so cpu_numcores() returns random values, which in turn crashes get_sys_info(). To fix the issue we place probecpu() before board_early_init_f() in an initialization sequence. Booting on the following boards should be revived now: mpc8540ads mpc8541cds mpc8548cds mpc8555cds mpc8560ads mpc8568mds mpc8569mds and maybe more.

commit 0e870980a64584a591af775bb9c9fe9450124df9 ("8xxx: Removed
CONFIG_NUM_CPUS from 85xx/86xx") breaks U-Boot on various boards,
namely the ones that call get_sys_info() from board_early_init_f().

get_sys_info() calls cpu_numcores(), which depends on probecpu()
being called before. But probecpu() is called after board_early_init_f(),
and so cpu_numcores() returns random values, which in turn crashes
get_sys_info().

To fix the issue we place probecpu() before board_early_init_f()
in an initialization sequence.

Booting on the following boards should be revived now:
 mpc8540ads
 mpc8541cds
 mpc8548cds
 mpc8555cds
 mpc8560ads
 mpc8568mds
 mpc8569mds
 and maybe more.
