* MIPS: Flush data cache upon relocationStefan Roese2008-12-10-7/+21
| | | | | | | | | This patch now adds a flush to the data cache upon relocation. The current implementation is missing this. Only a comment states that it should be done. So let's really do it now. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>
* MIPS: Add CONFIG_SKIP_LOWLEVEL_INITStefan Roese2008-12-10-0/+4
| | | | | | | | | | | This patch adds the CONFIG_SKIP_LOWLEVEL_INIT option to start.S. This enables support for boards where the lowlevel initialization is already done when U-Boot runs (e.g. via OnChip ROM). This will be used in the upcoming VCTH board support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM.

| * mpc8641: Support 36-bit physical addressingBecky Bruce2008-11-10-11/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * mpc8641: Change 32-bit memory mapBecky Bruce2008-11-10-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 These get horribly out of date, and it's a simple matter to look at the defines to see what they are set to since everything is right here in the same file.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>
| * mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLYBecky Bruce2008-11-10-10/+10
| | | | | | | | | | | | | | | | | | | | | | 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>
| * mpc86xx: Use SRR0/1/rfi to enable address translation, not blrBecky Bruce2008-11-10-11/+8
| | | | | | | | | | | | | | | | | | | | 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>
| * mpc86xx: Move setup_bats into cpu_init_fBecky Bruce2008-11-10-5/+4
| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | We put the bootpg for the secondary cpus into memory and use BPTR to get to it. This is a step towards converting to the ePAPR boot methodology. Also, the code is written to deal properly with more than 4GB of RAM. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
| * | powerpc 86xx: Handle CCSR relocation earlierBecky Bruce2008-11-03-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
