2011-01-14mpc85xx boards: initdram() cleanup/bugfixBecky Bruce
Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-01-2385xx: Introduce CONFIG_SYS_PCI*_MEM_VIRT for FSL boardsKumar Gala
Introduce a new define to seperate out the virtual address that PCI memory is at from the physical address. In most situations these are mapped 1:1. However any code accessing the bus should use VIRT. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
2009-01-2385xx: Use CONFIG_SYS_{PCI*,RIO*}_MEM_PHYS for physical address on FSL boardsKumar Gala
Use the _MEM_PHYS defines instead of _MEM_BUS for LAW and real address fields of TLBs. This is what we should have always been using from the start. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
2009-01-2385xx: Convert CONFIG_SYS_{PCI*,RIO*}_MEM_BASE to _MEM_BUS for FSL boardsKumar Gala
Use CONFIG_SYS_{PCI,RIO}_MEM_BUS for the bus relative address instead of _MEM_BASE so we are more explicit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>

2008-03-2685xx: Add the concept of CFG_CCSRBAR_PHYSKumar Gala
When we go to 36-bit physical addresses we need to keep the concept of the physical CCSRBAR address seperate from the virtual one. For the majority of boards CFG_CCSBAR_PHYS == CFG_CCSRBAR Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
