mpc85xx, mpc86xx: Fix gd->cpu pointer after relocation

2009-12-15T21:45:51+00:00

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.

This bug was introduced in commit
a0e2066f392782730f0398095e583c87812d97f2.

mpc85xx: Fix booting on various boards

2009-10-16T15:21:56+00:00

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.

ppc/8xxx: relocate cpu pointer in global data

2009-09-08T14:10:04+00:00

Now that we have a pointer to the cpu struct we need to relocate it once
we get into ram.

Standardize mem_malloc_init() implementation

This lays the groundwork to allow architectures to share a common
mem_malloc_init().

Note that the x86 implementation was not modified as it did not fit the
mold of all other architectures.
