u-boot.git/cpu/mpc86xx, branch v2009.11

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.

ppc/85xx/86xx: Device tree fixup for number of cores

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

Fixing the number of cores in the device tree based on the actual number of
cores on the system.  With this same device tree image can be used for dual
core and single core members of otherwise exactly same SOC.

For example:
* P2020RDB and P2010RDB
* P1020RDB and P1011RDB
* MPC8641D and MPC8641

ppc/85xx,86xx: Handling Unknown SOC version

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

Incase the system is detected with Unknown SVR, let the system boot
with a default value and a proper message.

Now with dynamic detection of SOC properties from SVR, this is necessary
to prevent a crash.

8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xx

2009-08-28T22:12:38+00:00

The number of CPUs are getting detected dynamically by checking the
processor SVR value.  Also removed CONFIG_NUM_CPUS references from all
the platforms with 85xx/86xx processors.

This can help to use the same u-boot image across the platforms.

Also revamped and corrected few Freescale Copyright messages.

8xxx: Refactored common cpu specific code for 85xx/86xx into one file.

2009-08-28T22:12:38+00:00

Removed same code pieces from cpu/mpc85xx/cpu.c and cpu/mpc86xx/cpu.c
and moved to cpu/mpc8xxx/cpu.c(new file)

86xx: Remove redudant PLATFORM_CPPFLAGS

2009-08-28T22:12:37+00:00

For historic reasons we had defined some additional PLATFORM_CPPFLAGS like:

PLATFORM_CPPFLAGS += -DCONFIG_MPC86xx=1
PLATFORM_CPPFLAGS += -DCONFIG_MPC8641=1

However these are all captured in the config.h and thus redudant.  Also
moved common 86xx flags into cpu/mpc86xx/config.mk.

86xx: Rename ccsr_ddr's sdram_mode_1, sdram_cfg_1 fields

2009-07-22T14:43:47+00:00

Rename sdram_mode_1 to sdram_mode and sdram_cfg_1 to sdram_cfg to match
the 86xx user's manual and other Freescale architectures

previous CONFIG_DDR_ECC
