ppc: Use r12 instead of r14 as GOT pointer.

2010-01-26T18:30:13+00:00

r14 is not supposed to be clobbered by functions. Switch
to r12 and call GET_GOT when needed. This will allow u-boot
to loose the -ffixed-r14 gcc option.

ppc: Loose GOT access in IRQ

2010-01-26T18:30:12+00:00

Using the GOT in IRQ handlers requires r14 to be -ffixed-r14.
Avoid this by relocatate transfer_to_handler too.
This will allow to free up r14 later on.

relocation: Do not relocate NULL pointers.

2009-10-08T07:33:36+00:00

NULL is an absolute value and should not be relocated.
After this correction code like:
 void weak_fun(void) __attribute__((weak));
 printf("weak_fun:%p\n", weak_fun);
will still print null after relocation.

74xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache

2008-10-30T23:25:08+00:00

The patch is following the commit 392438406041415fe64ab8748ec5ab5ad01d1cf7

mpc86xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache

This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.

lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

also, the r2 is used as global data pointer.

PPC: Create and use CONFIG_HIGH_BATS

2008-06-03T15:48:41+00:00

Change all code that conditionally operates on high bat
registers (that is, BATs 4-7) to look at CONFIG_HIGH_BATS
instead of the myriad ways this is done now.  Define the option
for every config for which high bats are supported (and
enabled by early boot, on parts where they're not always
enabled)

[PATCH] Add support for Prodrive P3M750 & P3M7448 (P3Mx) boards

2006-11-29T15:14:05+00:00

This patch adds support for the Prodrive P3M750 (PPC750 & MV64460)
and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are
quite similar and share the same board directory "prodrive/p3mx"
and the same config file "p3mx.h".
