2009-07-21powerpc: updates for the keymile boardsHeiko Schocher
- CONFIG_SYS_MAX_I2C_BUS changed to 1 We use only one I2C hardwarecontroller on this boards, so change the CONFIG_SYS_MAX_I2C_BUS to 1. - common: dont print errormsg if second IVM Block lacks. - 82xx, mgcoge: fix double mtdpart entry in environment - 82xx, mgcoge: activate on second Flash the second bank. - common: CONFIG_ENV_SIZE 0x4000 for all keymile boards - common: Change malloc size to 1MByte for all Keymile boards We need a bigger malloc area for the environment support (128k) on some Keymile boards (kmeter1) and the upcoming UBI support. Change it to 1MB for all Keymile boards to be on the save side. Also define CONFIG_SYS_64BIT_VSPRINTF which is needed for UBI/UBIFS support. - Add UBI support to all Keymile boards - change manner of writing "/localbus/ranges" node instead of writting the complete "/localbus/ranges" node before booting Linux, only update the ranges entries which gets dynamical detected (size of flashes). This is needed, because keymile adds in the DTS "/localbus/ranges" node entries, which u-boot must not overwrite/delete. - kmeter, mgcoge: define 2 seperate regions needed for the Intel P30 chips The Intel P30 chip has 2 non-identical chips on one die, so we need to define 2 seperate regions that are scanned by physmap_of independantly. - kmeter1: Add MTD concat support to Keymile boards - 82xx, mgcoge: add "unlock=yes" to default environment - added CONFIG_MTD_DEVICE to get in sync with mainline code Signed-off-by: Heiko Schocher <hs@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
2009-06-12i2c.h: Provide a default CONFIG_SYS_I2C_SLAVE valuePeter Tyser
Many boards/controllers/drivers don't support an I2C slave interface, however CONFIG_SYS_I2C_SLAVE is used in common code so provide a default Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-02-12i2c.h: drop i2c_reg_{read, write} hack for Blackfin partsMike Frysinger
The Blackfin i2c driver has been rewritten thus the special ifdefs in the common code are no longer needed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-12-15i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi
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.

2008-10-18I2C: adding new "i2c bus" Command to the I2C Subsystem.Heiko Schocher
With this Command it is possible to add new I2C Busses, which are behind 1 .. n I2C Muxes. Details see README. Signed-off-by: Heiko Schocher <hs@denx.de>
2008-10-18soft_i2c: prevent compiler warnings if driver does not use CPU Pins.Heiko Schocher
This patch fixes the following warnings, when using the soft_i2c driver using no CPU pins on MPC82xx or MPC8xx systems: soft_i2c.c: In function 'send_reset': soft_i2c.c:93: warning: unused variable 'immr' soft_i2c.c: In function 'send_start': soft_i2c.c:124: warning: unused variable 'immr' soft_i2c.c: In function 'send_stop': soft_i2c.c:146: warning: unused variable 'immr' soft_i2c.c: In function 'send_ack': soft_i2c.c:171: warning: unused variable 'immr' soft_i2c.c: In function 'write_byte': soft_i2c.c:196: warning: unused variable 'immr' soft_i2c.c: In function 'read_byte': soft_i2c.c:244: warning: unused variable 'immr' Signed-off-by: Heiko Schocher <hs@denx.de>
2008-05-21Big white-space cleanup.Wolfgang Denk
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>

2007-02-20[PATCH] PPC4xx: Add support for multiple I2C bussesStefan Roese
This patch adds support for multiple I2C busses on the PPC4xx platforms. Define CONFIG_I2C_MULTI_BUS in the board config file to make use of this feature. It also merges the 405 and 440 i2c header files into one common file 4xx_i2c.h. Also the 4xx i2c reset procedure is reworked since I experienced some problems with the first access on the 440SPe Katmai board. Signed-off-by: Stefan Roese <sr@denx.de>

2006-11-03Add support for multiple I2C busesBen Warren
Hello, Attached is a patch providing support for multiple I2C buses at the command level. The second part of the patch includes an implementation for the MPC834x CPU and MPC8349EMDS board. /*** Note: This patch replaces ticket DNX#2006083042000018 ***/ Signed-off-by: Ben Warren <bwarren@qstreams.com> Overview: 1. Include new 'i2c' command (based on USB implementation) using CONFIG_I2C_CMD_TREE. 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that the commands to change bus number and speed are only available under the new 'i2c' command mentioned in the first bullet. 3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form of an array of bus-device pairs. Otherwise, it is an array of uchar. CHANGELOG: Added new 'i2c' master command for all I2C interaction. This is conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for setting I2C bus speed as well as changing the active bus if the board has more than one (conditionally compiled with CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses. Updated README. regards, Ben
2003-03-14* Avoid flicker on the TRAB's VFD by synchronizing the enable withwdenk
the HSYNC/VSYNC. Requires new CPLD code (Version 101 for Rev. 100 boards, version 153 for Rev. 200 boards). * Patch by Vladimir Gurevich, 12 Mar 2003: Fix relocation problem of statically initialized string pointers in common/cmd_pci.c * Patch by Kai-Uwe Blöm, 12 Mar 2003: Cleanup & bug fixes for JFFS2 code: - the memory mangement was broken. It caused havoc on malloc by writing beyond the block boundaries. - the length calculation for files was wrong, sometimes resulting in short file reads. - data copying now optionally takes fragment version numbers into account, to avoid copying from older data. See doc/README.JFFS2 for details.
