* 85xx: Use print_size to report amount of memory not mapped by TLBsKumar Gala2009-06-12-1/+1

* 85xx: bugfix for reading maximum TLB size on mpc85xxFredrik Arnerup2009-06-09-1/+1
| | | | | | | | | | | | | The MAXSIZE field in the TLB1CFG register is 4 bits, not 8 bits. This made setup_ddr_tlbs() try to set up a TLB larger than the e500 maximum (256 MB) which made u-boot hang in board_init_f() when trying to create a new stack in RAM. I have an mpc8540 with one 1GB dimm. Signed-off-by: Fredrik Arnerup <fredrik.arnerup@edgeware.tv> Signed-off-by: Andy Fleming <afleming@freescale.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Fix how we map DDR memoryKumar Gala2009-02-16-47/+27
| | | | | | | | | Previously we only allowed power-of-two memory sizes and didnt handle >2G of memory. Now we will map up to CONFIG_MAX_MEM_MAPPED and should properly handle any size that we can make in the TLBs we have available to us Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Change DDR tlb start entry to CONFIG param for 85xxHaiying Wang2009-01-13-1/+5
| | | | | | | So that we can locate the DDR tlb start entry to the value other than 8. By default, it is still 8. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>

* FSL DDR: Add e500 TLB helper for DDR codeKumar Gala2008-08-27-0/+64
| | | | | | | Provide a helper function that board code can call to map TLBs when setting up DDR. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 85xx: Get ride of old TLB setup codeKumar Gala2008-01-17-2/+0
| | | | | | | Now that all boards have been converted, remove old config code and the config option for the new style. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Introduce new tlb APIKumar Gala2008-01-17-0/+95
Add a set of functions to manipulate TLB entries: * set_tlb() - write a tlb entry * invalidate_tlb() - invalidate a tlb array * disable_tlb() - disable a variable size tlb entry * init_tlbs() - setup initial tlbs based on static table Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
