* mpc512x: Fix problem with I2C access before relocationStefan Roese2009-06-12-1/+1
| | | | | | | | | This is needed for the upcoming esd MECP5123 board port which uses I2C EEPROM for environment storage. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Reinhard Arlt <reinhard.arlt@esd-electronics.com> Acked-by: Heiko Schocher<hs@denx.de>
* MPC512x: remove include/mpc512x.hWolfgang Denk2009-06-12-1/+0
| | | | | | | | | | | | | | | | | | | | Move needed definitions (register descriptions etc.) from include/mpc512x.h into include/asm-ppc/immap_512x.h. Instead of using a #define'd register offset, use a function that provides the PATA controller's base address. All the rest of include/mpc512x.h are register offset definitions which can be eliminated by proper use of C structures. There are only a few register offsets remaining that are needed in cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h which is intended as a temporary workaround only. In a later patch this file will be removed, too, and then auto-generated from the respective C structs. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>
* MPC512x: use I/O accessors instead of pointer accessesWolfgang Denk2009-06-12-26/+30
| | | | | | | | This commit changes the MPC512x code to use I/O accessor calls (i.e. out_*() and in_*()) instead of using deprecated pointer accesses. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: John Rigby <jcrigby@gmail.com>
* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-12-14/+0
| | | | | | | | | | | | | New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.

* i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi2008-12-15-17/+0
| | | | | | | | | | All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h.
