Update CHANGELOG, minor Coding Style cleanup. Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-08-1485xx: Fix addrmap to include memoryKumar Gala
When we init the addrmap based on the TLB we will not end up getting the TLB that covers memory if we are using SPD. The reason is we haven't relocated at the point that we setup the memory TLB and thus it will not get setup in the addrmap. Instead we can just walk over the TLB array after we've relocated and see all the TLBs that have been set and use that information to populate the initial addrmap. By doing this we insure that we get the TLB entries that cover memory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-06-1285xx: Use print_size to report amount of memory not mapped by TLBsKumar Gala

2009-06-0985xx: bugfix for reading maximum TLB size on mpc85xxFredrik Arnerup
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>
2009-02-1685xx: Fix how we map DDR memoryKumar Gala
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>
2009-01-13Change DDR tlb start entry to CONFIG param for 85xxHaiying Wang
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>

2008-08-27FSL DDR: Add e500 TLB helper for DDR codeKumar Gala
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>

2008-01-1785xx: Get ride of old TLB setup codeKumar Gala
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>
2008-01-1785xx: Introduce new tlb APIKumar Gala
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>
