* Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser2010-04-13-763/+0
| | | | | | | | This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* mpc86xx: set the DDR BATs after calculating true DDR sizeTimur Tabi2010-03-30-1/+5
| | | | | | | | | | | | | | | | | | | | After determining how much DDR is actually in the system, set DBAT0 and IBAT0 accordingly. This ensures that the CPU won't attempt to access (via speculation) addresses outside of actual memory. On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB and kept that way. If the system has less than 2GB of memory (typical for an MPC8610 HPCD), the CPU may attempt to access this memory during speculation. The zlib code is notorious for generating such memory reads, and indeed on the MPC8610, uncompressing the Linux kernel causes a machine check (without this patch). Currently we are limited to power of two sized DDR since we only use a single bat. If a non-power of two size is used that is less than CONFIG_MAX_MEM_MAPPED u-boot will crash.

* ppc/85xx: Add tracking of TLB CAM usageKumar Gala2010-01-05-0/+2
| | | | | | | | | We need to track which TLB CAM entries are used to allow us to "dynamically" allocate entries later in the code. For example the SPD DDR code today hard codes which TLB entries it uses. We can now make that pick entries that are free. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix "ppc/85xx: Clean up use of LAWAR defines" breakageWolfgang Denk2009-09-25-1/+1
| | | | | | | | | Commit 002741ae86 modified include/asm-ppc/mmu.h such that the LAWAR_ defines were only enabled for the 83xx platform, but they are also needed on MPC512x system. Enabling these for E300 systems seems thus more appropriate. Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc/85xx: Clean up use of LAWAR definesKumar Gala2009-09-24-7/+2
| | | | | | | | | On 85xx platforms we shouldn't be using any LAWAR_* defines but using the LAW_* ones provided by fsl-law.h. Rename any such uses and limit the LAWAR_ to the 83xx platform as the only user so we will get compile errors in the future. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/85xx: Repack tlb_table to save spaceKumar Gala2009-09-15-11/+10
| | | | | | | | We can pack the initial tlb_table in MAS register format and use write_tlb to set things up. This savings can be helpful for NAND style first stage boot loaders. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/85xx: Introduce low level write_tlb functionKumar Gala2009-09-15-0/+4
| | | | | | | | | Factor out the code we use to actually write a tlb entry. set_tlb is a logical view of the TLB while write_tlb is a low level matching the MAS registers. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/85xx: Add a simple function to search the TLBKumar Gala2009-09-08-2/+5
| | | | | | | | | | | Allow us to search the TLB array based on an address. This is useful if we want to change an entry but dont know where it happens to be located. For example, the boot page mapping we use on MP or the flash TLB that we change the WIMGE settings for after we've relocated. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc86xx: Add support to populate addr map based on BATsBecky Bruce2009-02-10-3/+13
| | | | | | | If CONFIG_ADDR_MAP is enabled, update the address map whenever we write a bat. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>
* powerpc: Move duplicated BAT defines to mmu.hBecky Bruce2009-02-10-13/+44
| | | | | | | | | | | The BAT fields are architected; there's no need for these to be in cpu-specific files. Drop the duplication and move these to include/asm-ppc/mmu.h. Also, remove the BL_xxx defines that were only used by the alaska board, and switch to using the BATU_BL_xxx defines used by all the other boards. The BL_ defines previously in use had to be shifted into the proper position for use, which was inefficient. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>

* FSL DDR: Add e500 TLB helper for DDR codeKumar Gala2008-08-27-0/+1
| | | | | | | 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>
* PPC: Add print_bats() to lib_ppc/bat_rw.cBecky Bruce2008-06-03-0/+1
| | | | | | | | | This function prints the values of all the BAT register pairs - I needed this for debug earlier this week; adding it to lib_ppc so others can use it (and add it to reginfo commands if so desired). Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
* PPC: Change lib_ppc/bat_rw.c to use high batsBecky Bruce2008-06-03-1/+5
| | | | | | | | Currently, this code only deals with BATs 0-3, which makes it useless on systems that support BATs 4-7. Add the support for these registers. Signed-off-by: Becky Bruce <Becky.bruce@freescale.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-2/+2
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* ppc4xx: program_tlb now uses 64bit physical addessStefan Roese2008-03-15-9/+9
| | | | | | | | This patch changes the physical addess parameter from 32bit to 64bit. This is needed for 36bit 4xx platforms to access areas located beyond the 4GB border, like SoC peripherals (EBC etc.). Signed-off-by: Stefan Roese <sr@denx.de>
* Remove duplicate defines for ARRAY_SIZEKumar Gala2008-02-22-1/+0
| | | | | | | A few duplicate of the ARRAY_SIZE macro sneaked in since we put the define in common.h. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Introduce new tlb APIKumar Gala2008-01-17-0/+31
| | | | | | | | | | 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>
* Reworked FSL Book-E TLB macros to be more readableKumar Gala2008-01-09-0/+13
| | | | | | | | | | | The old macros made it difficult to know what WIMGE and perm bits were set for a TLB entry. Actually use the bit masks for these items since they are only a single bit. Also moved the macros into mmu.h out of e500.h since they aren't specific to e500. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Use FSL Book-E MMU macros from Linux KernelKumar Gala2008-01-09-47/+53

| * Use standard LAWAR_TRGT_IF_* defines for LAW setup on 85xxKumar Gala2007-12-11-1/+3
| | | | | | | | | | | | | | | | We already had defines for LAWAR_TRGT_IF_* that we should use rather than creating new ones. Also, added some missing defines for PCIE targets. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | ppc4xx: Add change_tlb function to modify I attribute of TLB(s)Stefan Roese2007-10-31-0/+1
|/ | | | | | | This function is used to either turn cache on or off in a specific memory area. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Add remove_tlb() function to remove a mem area from TLB setupStefan Roese2007-07-16-0/+3
| | | | | | | | | | The new function remove_tlb() can be used to remove the TLB's used to map a specific memory region. This is especially useful for the DDR(2) setup routines which configure the SDRAM area temporarily as a cached area (for speedup on auto-calibration and ECC generation) and later need this area uncached for normal usage.

* Changed BOOKE_PAGESZ_nGB to BOOKE_PAGESZ_nGAndy Fleming2007-04-23-2/+2

* [PATCH] PPC4xx: Add 440SP(e) DDR2 SPD DIMM supportStefan Roese2007-02-20-42/+166
| | | | | | | | | | | | | | | | | This patch adds support for the DDR2 controller used on the 440SP and 440SPe. It is tested on the Katmai (440SPe) eval board and works fine with the following DIMM modules: - Corsair CM2X512-5400C4 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM) This patch also adds the nice functionality to dynamically create the TLB entries for the SDRAM (tlb.c). So we should never run into such problems with wrong (too short) TLB initialization again on these platforms. Signed-off-by: Stefan Roese <sr@denx.de>
