2008-11-18Align end of bss by 4 bytesSelvamuthukumar
Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected.

2008-11-11mpc8641: fix address-cells default in old .dts detectionBecky Bruce
address-cells defaults to 2, not 1; so in the unlikely event that it isn't specified, this patch is required for correct operation. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10lib_ppc: Move trap_init to occur earlierBecky Bruce
Doing trap_init immediately once we're running from RAM means we're no longer dependent on the physical location of the flash on non-BookE platforms. Before trap_init, those platforms switch to real mode and go to 0xfff00100 on exception. After the switch, they go to 0x00000100 This makes it easier to move the flash location.

2008-11-10mpc8641: Try to detect old .dts filesBecky Bruce
Since we've changed the memory map of the board, be nice and add some checking to try to catch out-of-date .dts files. We do this by checking the CCSRBAR location in the .dts and comparing it to the CCSRBAR location in u-boot. If they don't match, a warning msg is printed. This isn't foolproof, but it's simple and will catch most of the cases where an out-of-date .dts is present, including all of the cases where a new u-boot is used with an old standard MPC8641 .dts file as supplied with Linux.

2008-11-10toplevel Makefile: Add MPC8641HPCN_36BIT targetBecky Bruce

2008-11-10mpc8641: Support 36-bit physical addressingBecky Bruce
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 <becky.bruce@freescale.com>
2008-11-10mpc8641: Change 32-bit memory mapBecky Bruce
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 <becky.bruce@freescale.com>
2008-11-10mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLYBecky Bruce
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 <becky.bruce@freescale.com>
2008-11-10mpc86xx: Use SRR0/1/rfi to enable address translation, not blrBecky Bruce
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 <becky.bruce@freescale.com>

2008-11-10mpc8641: Drop imaginary second flash bank, map 8MBBecky Bruce
There's a lot of setup and foo for the second flash bank. The problem is, this board doesn't actually have one. Clean this up. Also, the flash is 8M in size. Get rid of the confusing aliased overmapping, and just map 8M. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc8641: only define CONFIG_ENV_SIZE onceBecky Bruce
It's currently defined twice inside in an if/else block, but both halves set the same value. Move the define outside the if. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc86xx: Move setup_bats into cpu_init_fBecky Bruce
In order to later allow for a physical relocation of the flash, setup_bats, which sets up the final BAT mapping for the board, needs to happen *after* init_laws(). Otherwise, there will be no window programmed for the flash at the new physical location at the point when we change the mmu translation. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

2008-11-03powerpc 86xx: Handle CCSR relocation earlierBecky Bruce
Currently, the CCSR gets relocated while translation is enabled, meaning we need 2 BAT translations to get to both the old location and the new location. Also, the DEFAULT CCSR location has a dependency on the BAT that maps the FLASH region. Moving the relocation removes this unnecessary dependency. This makes it easier and more intutive to modify the board's memory map. Swap BATs 3 and 4 on 8610 so that all 86xx boards use the same BAT for CCSR space.
