* arm926ejs: timer: Replace bss variable by gdrHeiko Schocher2011-02-02-16/+32
| | | | | | | | | | | | | | | | | | | | | Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in the arm926ejs timers implementation. The usage of bss values in drivers before initialisation of bss is forbidden. In that special case some data in .rel.dyn gets corrupted. This patch is similiar to the patch Dirk Behme posted for the armv7/omap-common/timer.c and added suggestions from Reinhard Meyer.

* ARM: Avoid compiler optimization for readb, writeb and friends.Alexander Holler2011-02-02-12/+20
| | | | | | | | | | | | | | | | | | | | | gcc 4.5.1 seems to ignore (at least some) volatile definitions, avoid that as done in the kernel. Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that gcc version to ignore the volatile type qualifier used e.g. in __arch_getl(). Anyway, using a definition as in the kernel headers avoids such optimizations when gcc 4.5.1 is used. Maybe the headers as used in the current linux-kernel should be used, but to avoid large changes, I've just added a small change to the current headers.

* SPI: mxc_spi: add SPI clock calculation and setup to the driverAnatolij Gustschin2011-02-02-1/+22
| | | | | | | | | | | | | The MXC SPI driver didn't calculate the SPI clock up to now and just used highest possible divider 512 for DATA RATE in the control register. This results in very low transfer rates. The patch adds code to calculate and setup the SPI clock frequency for transfers.

* SPI: mxc_spi: fix swapping bug and add missing swapping in unaligned rx caseAnatolij Gustschin2011-02-02-5/+4
| | | | | | | | | | | | | | | We need to shift only one time in each cycle in the swapping loop for unaligned tx case. Currently two byte shift operations are performed in each loop cycle causing zero gaps in the transmited data, so not all data scheduled for transmition is actually transmited. The proper swapping in unaligned rx case is missing, so add it as we need to put the received data into the rx buffer in the correct byte order.

* I2C: mxc_i2c: address failure with mx35 processorStefano Babic2011-02-02-18/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is sporadic failures when more as one I2C slave is on the bus and the processor tries to communicate with more as one slave. The problem was seen on a mx35pdk (two I2C slaves, PMIC controller and CAN/RTC chip). The current driver uses the IIF bit in the status register to check if the bus is busy or not. According to the manual, this is not correct, because the IIB bit should be checked. Not only, to check if a transfer is finished must be checked the ICF bit, and this is not tested at all. This patch comes from analyse with a corresponding driver provided by Freescale as part of the LTIB tool. Comparing the two drivers, it appears that the current u-boot driver checks the wrong bits, and depending on race condition, the transfer can be successful or not. The patch gets rid also of own debug function (DPRINTF), replaced with the general debug(). Tested on Freescale mx35pdk.
