ppc: Use r12 instead of r14 as GOT pointer.

2010-01-26T18:30:13Z

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. Signed-off-by: Joakim Tjernlund

ppc: Loose GOT access in IRQ

2010-01-26T18:30:12Z

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. Signed-off-by: Joakim Tjernlund

relocation: Do not relocate NULL pointers.

2009-10-08T07:33:36Z

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. Signed-off-by: Joakim Tjernlund

Coding style cleanup, update CHANGELOG.

Update U-Boot's build timestamp on every compile

Use the GNU 'date' command to auto-generate a new U-Boot timestamp on every compile. Signed-off-by: Peter Tyser

mpc8641: Support 36-bit physical addressing

2008-11-10T16:10:05Z

This patch creates a memory map with all the devices in 36-bit physical space, in addition to the 32-bit map. The CCSR relocation is moved (again, sorry) to allow for the physical address to be 36 bits - this requires translation to be enabled. With 36-bit physical addressing enabled, we are no longer running with VA=PA translations. This means we have to distinguish between the two in the config file. The existing region name is used to indicate the virtual address, and a _PHYS variety is created to represent the physical address. Large physical addressing is not enabled by default. Set CONFIG_PHYS_64BIT in the config file to turn this on. Signed-off-by: Becky Bruce

mpc8641: Change 32-bit memory map

2008-11-10T16:10:04Z

The memory map on the 8641hpcn is modified to look more like the 85xx boards; this is a step towards a more standardized layout going forward. As part of this change, we now relocate the flash. The regions for some of the mappings were far larger than they needed to be. I have reduced the mappings to match the actual sizes supported by the hardware. In addition I have removed the comments at the head of the BAT blocks in the config file, rather than updating them. These get horribly out of date, and it's a simple matter to look at the defines to see what they are set to since everything is right here in the same file. Documentation has been changed to reflect the new map, as this change is user visible, and affects the OS which runs post-uboot. Signed-off-by: Becky Bruce

mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLY

2008-11-10T16:10:04Z

We define CONFIG_MONITOR_BASE_EARLY to define the initial location of the bootpage in flash. Use this to create an early mapping definition for the FLASH, and change the early_bats code to use this. This change facilitates the relocation of the flash since the early mappings are no longer tied to the final location of the flash. Signed-off-by: Becky Bruce

mpc86xx: Use SRR0/1/rfi to enable address translation, not blr

2008-11-10T16:10:03Z

Using a mtmsr/blr means that you have to be executing at the same virtual address once you enable translation. This is unnecessarily restrictive, and is not really how this is usually done. Change it to use the more common mtspr SRR0/SRR1 and rfi method. Signed-off-by: Becky Bruce
