* 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>
* Stop using immap_t on 85xxKumar Gala2007-12-11-32/+18
| | | | | | | | In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_*_ADDR as the base of the registers instead of getting it via &immap. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Stop using immap_t for cpm offset on 85xxKumar Gala2007-12-11-66/+63
| | | | | | | | In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_CPM_ADDR as the base of the CPM registers instead of getting it via &immap->im_cpm. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Stop using immap_t for guts offset on 85xxKumar Gala2007-12-11-6/+5
| | | | | | | | In the future the offsets to various blocks may not be in same location. Move to using CFG_MPC85xx_GUTS_ADDR as the base of the guts registers instead of getting it via &immap->im_gur. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Setting MSR[DE] in do_reseturwithsughosh@gmail.com2007-10-19-1/+6
| | | | | | | | Hello, This patch ensures the soft reset of the board for the 85xx boards by setting the MSR[DE] in the do_reset function. Signed-off-by: Sughosh Ganu <urwithsughosh@gmail.com>

* Remove magic numbers from cache related operations for mpc85xxKumar Gala2007-10-19-4/+4
| | | | | | | The mpc85xx start code uses some magic numbers that we actually have #defines for in <config.h> so use those instead. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx io out functions need sync after write.Ed Swarthout2007-09-26-0/+5

* 85xxCDS: Add make targets for legacy systems.Randy Vinson2007-08-14-1/+1
| | | | | | | | The PCI ID select values on the Arcadia main board differ depending on the version of the hardware. The standard configuration supports Rev 3.1. The legacy target supports Rev 2.x. Signed-off-by Randy Vinson <rvinson@mvista.com>

* Empirically set cpo and clk_adjust for mpc85xx DDR2 supportHaiying Wang2007-08-14-5/+7
| | | | | | | | | | | | | | This patch is against u-boot-mpc85xx.git of www.denx.com Setting cpo to 0x9 for frequencies higher than 333MHz is verified on both MPC8548CDS board and MPC8568MDS board, especially for supporting 533MHz DDR2. Setting clk_adjust to 0x6(3/4 late cycle) for MPC8568MDS board is for DDR2 on all current board versions especially ver 1.92 or later to bring up. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
* Use an absolute address when jumping out of 4k boot pageKumar Gala2007-08-14-29/+24
| | | | | | | On e500 when we leave the 4k boot page we should use an absolute address since we don't know where the board code may want us to be really running at. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 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). Signed-off-by: Greg Davis <DavisG@embeddedplanet.com>
* Fix minor 85xx warningsAndy Fleming2007-08-14-1/+3
| | | | | | | | | | | Some patches had inserted warnings into the build: * mpc8560ads declared data without using it * cpu_init declared ecm and immap without using it in all CONFIGs * MPC8548CDS.h had its default filenames changed so that they contained "\m" in the paths. Made the defaults not Windows-specific (or anything-specific) Signed-off-by: Andy Fleming <afleming@freescale.com>
* 85xx start.S cleanup and exception supportAndy Fleming2007-08-14-298/+319
| | | | | | | | | | | | | | | | | | | | | | | | | | From: Ed Swarthout <Ed.Swarthout@freescale.com> Support external interrupts from platform to eliminate system hangs. Define CONFIG_INTERRUPTS board configure option to enable. Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC. Remove extra cpu initialization redundant with hardware initialization. Whitespace cleanup. Define and use _START_OFFSET consistent with other processors using ppc_asm.tmpl Move additional code from .text to boot page to make room for exception vectors at start of image. Handle Machine Check, External and Critical exceptions. Fix e500 machine check error determination in traps.c TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
