* i2c, mpc83xx: add CONFIG_SYS_I2C_INIT_BOARD for fsl_i2cHeiko Schocher2009-07-21-0/+20
| | | | | | | | | | | | | | | | | | | | | | This patch adds the possibility to call a board specific i2c bus reset routine for the fsl_i2c bus driver, and adds this option for the keymile kmeter1 board. The deblock sequence for this board is implemented and tested in the following way: CR = 0x20 (release SDA and SCL pin) CR = 0xa0 (start read) dummy read dummy read if 2. dummy read == 0x00 3. dummy read CR = 0x80 (SDA and SCL now 1 SR = 0x86) CR = 0x00 (Modul reset SR=0x81) CR = 0x80 (SDA and SCL = 1, SR = 0x81) Signed-off-by: Heiko Schocher <hs@denx.de>
* powerpc: updates for the keymile boardsHeiko Schocher2009-07-21-3/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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>
* 8xx: add support for new keymile kmsupx4 board.Heiko Schocher2009-03-18-0/+4
| | | | | | | | | | | | | This patch adds support for the kmsupx4 board from Keymile, based on a Freescale MPC852T CPU - serial console on SMC1 - 32 MB SDRAM - 32 MB NOR Flash - Ethernet over SCC3 - I2C Bitbang Signed-off-by: Heiko Schocher <hs@denx.de>
* 8xx, mgsuvd: rename board to a more generic nameHeiko Schocher2009-03-18-1/+1
| | | | | | | | | renaming the "mgsuvd" board port into "km8xx", because there come more similar boards from keymile. Compiling the mgsuvd board with "make mgsuvd_config" remains. Signed-off-by: Heiko Schocher <hs@denx.de>
* 83xx, kmeter1: add I2C, dtt, eeprom supportHeiko Schocher2009-03-05-1/+1
| | | | | | | | | | This patch adds I2C support for the Keymile kmeter1 board. It uses the First I2C Controller from the CPU, for accessing 4 temperature sensors, an eeprom with IVM data and the booteeprom over a pca9547 mux.

* mgcoge, mgsuvd: add board specific I2C deblocking mechanism.Heiko Schocher2008-10-18-0/+209
As documented in doc/I2C_Edge_Conditions, adding a board specific deblocking mechanism via CFG_I2C_INIT_BOARD for the mgcoge and mgsuvd board. This code was originally written by Keymile in association with Anatech and Atmel in 1998. The Code toggels the SCL until the SCA line goes to HIGH (max. 16 times). And after this, a start condition is sent. This is another approach to deblock the I2C Bus. The soft I2C driver actually sends 9 clocks with SDA High, and then a stop at the end, to deblock the I2C Bus. Maybe we should use the approach from Keymile as the new standard?
