* mpc83xx: Fix the incorrect dcbz operationDave Liu2006-11-03-34/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 834x rev1.x silicon has one CPU5 errata. The issue is when the data cache locked with HID0[DLOCK], the dcbz instruction looks like no-op inst. The right behavior of the data cache is when the data cache Locked with HID0[DLOCK], the dcbz instruction allocates new tags in cache. The 834x rev3.0 and later and 8360 have not this bug inside. So, when 834x rev3.0/8360 are working with ECC, the dcbz instruction will corrupt the stack in cache, the processor will checkstop reset. However, the 834x rev1.x can work with ECC with these code, because the sillicon has this cache bug. The dcbz will not corrupt the stack in cache. Really, it is the fault code running on fault sillicon. This patch fix the incorrect dcbz operation. Instead of CPU FP writing to initialise the ECC. CHANGELOG: * Fix the incorrect dcbz operation instead of CPU FP writing to initialise the ECC memory. Otherwise, it will corrupt the stack in cache, The processor will checkstop reset.

* Multi-bus I2C implementation of MPC834xBen Warren2006-11-03-24/+144
| | | | | | | | | | | | | | | | | | | | | Hello, Attached is a patch implementing multiple I2C buses on the MPC834x CPU family and the MPC8349EMDS board in particular. This patch requires Patch 1 (Add support for multiple I2C buses). Testing was performed on a 533MHz board. /*** Note: This patch replaces ticket DNX#2006083042000027 ***/ Signed-off-by: Ben Warren <bwarren@qstreams.com> CHANGELOG: Implemented driver-level code to support two I2C buses on the MPC834x CPU family and the MPC8349EMDS board. Available I2C bus speeds are 50kHz, 100kHz and 400kHz on each bus. regards, Ben

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-16/+14
| | | | | | | | | | | | | | | | | | | | | 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.
