* 85xx: Fix the boot window issueDave Liu2008-12-19-8/+8
| | | | | | | | | | | | | | | | | | | | | | If one custom board is using the 8MB flash, it is set as FLASH_BASE = 0xef000000, TEXT_BASE = 0xef780000. The current start.S code will be broken at switch_as. It is because the TLB1[15] is set as 16MB page size, EPN = TEXT_BASE & 0xff000000, RPN = 0xff000000. For the 8MB flash case, the EPN = 0xefxxxxxx, RPN = 0xffxxxxxx. Assume the virt address of switch_as is 0xef7ff18c, the real address of the instruction at switch_as should be 0xff7ff18c. the 0xff7ff18c is out of the range of the default 8MB boot LAW window 0xff800000 - 0xffffffff. So when we switch to AS1 address space at switch_as, the core can't fetch the instruction at switch_as any more. It will cause broken issue. Signed-off-by: Dave Liu <daveliu@freescale.com>
* Set IVPR to kenrel entry point in second core boot pageHaiying Wang2008-12-19-0/+1
| | | | | | | | | | | Assuming the OSes exception vectors start from the base of kernel address, and the kernel physical starting address can be relocated to an non-zero address. This patch enables the second core to have a valid IVPR for debugger before kernel setting IVPR in CAMP mode. Otherwise, IVPR is 0x0 and it is not a valid value for second core which runs kernel at different physical address other than 0x0. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
* mpc8xxx: LCRR[CLKDIV] is sometimes five bitsTrent Piepho2008-12-19-2/+2
| | | | | | | | | | | | | | On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits instead of four. In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It should be safe as the fifth bit was defined as reserved and set to 0. Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

* mpc8[56]xx: Put localbus clock in device treeTrent Piepho2008-12-19-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Export the localbus frequency in the device tree, the same way the CPU, TB, CCB, and various other frequencies are exported in their respective device tree nodes. Some localbus devices need this information to be programed correctly, so it makes sense to export it along with the other frequencies. Unfortunately, when someone wrote the localbus dts bindings, they didn't bother to define what the "compatible" property should be. So it seems no one was quite sure what to put in their dts files. Based on current existing dts files in the kernel source, I've used "fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all of the 85xx devices, and are looked for by the Linux code. The eLBC is apparently not entirely backward compatible with the pq3 LBC and so eLBC equipped platforms like 8572 won't use pq3-localbus. For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems and is also looked for by the Linux code. On MPC8641, I've also used "fsl,mpc8641-localbus" as it is also commonly used in dts files, some of which don't use "fsl,elbc" or any other acceptable name to match on.

| * 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>

| | | | | | | | | | | | | | | | | | | | | | We define CONFIG_MONITOR_BASE_EARLY to define the initial location of the bootpage in flash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
