* 85xx: Don't icbi when unlocking the cacheKumar Gala2008-02-27-5/+2
| | | | | | | | | There is no reason to icbi when invalidating the temporary stack in the d-cache. Its impossible on e500 to have the i-cache contain any addresses in the temp stack and it can be problematic in generating transactions on the bus to non-valid addresses.

* Fix source for ECM error IVPRAndy Fleming2008-02-27-1/+1
| | | | | | | | The source vector for the ECM was being set to 2, but that's what the source vector for DDR was being set to. Change it to 1. Signed-off-by: Andy Fleming <afleming@freescale.com>
* Invalidate INIT_RAM TLB mappingsAndy Fleming2008-02-27-0/+11
| | | | | | | | | | | | | | | Commit 0db37dc... (and some others) changed the INIT_RAM TLB mappings to be unguarded. This collided with an existing "bug" where the mappings for the INIT_RAM were being kept around. This meant that speculative loads to those addresses were succeeding in the TLB, and going out to the bus, where they were causing an exception (there's nothing at that address). The Flash code was coincidentally causing such a speculative load. Rather than go back to mapping the INIT RAM as guarded, we fix it so that the entries for the INIT_RAM are invalidated. Thus the speculative loads will fail in the TLB, and have no effect. Signed-off-by: Andy Fleming <afleming@freescale.com>
* 85xx, 86xx: Determine I2C clock frequencies and store in global_dataTimur Tabi2008-02-14-0/+3
| | | | | | | | | Update global_data to define i2c1_clk and i2c2_clk to 85xx and 86xx. Update the get_clocks() function in 85xx and 86xx to determine the I2C clock frequency and store it in gd->i2c1_clk and gd->i2c2_clk. Signed-off-by: Timur Tabi <timur@freescale.com>
* PPC: Use r2 instead of r29 as global data pointerWolfgang Denk2008-02-14-1/+2
| | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

* 85xx: Get ride of old TLB setup codeKumar Gala2008-01-17-22/+0

* 85xx: Reworked initial processor initKumar Gala2008-01-17-72/+115
| | | | | | | | | | | | | | | | | | | Reworked the initial processor initialzation sequence: * introduced cpu_early_init_f that is run in address space 1 (AS=1) * Moved TLB/LAW and CCSR init into cpu_early_init_f() * Reworked initial asm code to do most of the core init before TLBs The main reasons for these changes are to allow handling of 36-bit phys addresses in the future and some of the issues that will exist when we do that. There are a few caveats on what can be initialized via the LAW and TLB static tables: * TLB entry 14/15 can't be initialized via the TLB table * any LAW that covers the implicit boot window (4G-8M to 4G) must map to the code that is currently executing. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Introduce new tlb APIKumar Gala2008-01-17-14/+99
| | | | | | | | | | 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>
* 85xx: Remove old style of LAW initKumar Gala2008-01-16-28/+0
| | | | | | All boards are now using the new fsl_law code so we can drop the old version. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Move LAW init code into CKumar Gala2008-01-16-0/+18
| | | | | | | | | | | Move the initialization of the LAWs into C code and provide an API to allow modification of LAWs after init. Board code is responsible to provide a law_table and num_law_entries. We should be able to use the same code on 86xx as well. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 85xx: add ability to upload QE firmwareTimur Tabi2008-01-09-0/+1
| | | | | | | | | | | Define the layout of a binary blob that contains a QE firmware and instructions on how to upload it. Add function qe_upload_firmware() to parse the blob and perform the actual upload. Add command-line command "qe fw" to take a firmware blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the 'firmware' device tree node if U-Boot has uploaded a firmware. Fully define 'struct rsp' in immap_qe.h to include the actual RISC Special Registers. Signed-off-by: Timur Tabi <timur@freescale.com>
* 85xx: Remove cache config from configs.hKumar Gala2008-01-09-2/+7
| | | | | | | | | Either use the standard defines in asm/cache.h or grab the information at runtime from the L1CFG SPR. Also, minor cleanup in cache.h to make the code a bit more readable. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Reworked FSL Book-E TLB macros to be more readableKumar Gala2008-01-09-13/+10
| | | | | | | | | | | 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>
* Handle Asynchronous DDR clock on 85xxKumar Gala2007-12-11-4/+43
| | | | | | | | | | The MPC8572 introduces the concept of an asynchronous DDR clock with regards to the platform clock. Introduce get_ddr_freq() to report the DDR freq regardless of sync/async mode. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Use an absolute address when jumping out of 4k boot pageKumar Gala2007-08-14-29/+24

* MPC85xx BA bits not set for 3-bit bank address DIMMAndy Fleming2007-08-14-1/+6
| | | | | | | | | | The current implementation does not set the number of bank address bits (BA) in the processor. The default assumes 2 logical bank bits. This works fine for a DIMM that uses devices with 4 internal banks (SPD byte17 = 0x4) but needs to be set appropriately for a DIMM that uses devices with 8 internal banks (SPD byte17 = 0x8).
