2011-02-02Add support for Freescale's mx35pdk board.Stefano Babic
The patch adds suupport for the Freescale's mx35pdk board (known as well as mx35_3stack). The board boots from the NOR flash. Following devices are supported: - two ethernet devices (FEC and SMC911x on debug board) - I2C - PMIC (MC13892) via I2C interface - UART - NOR flash (64MB) - NAND flash (2GB) - basic access to mc9sdz60 registers via I2C interface Signed-off-by: Stefano Babic <sbabic@denx.de>
2011-02-02SPI: mxc_spi: replace fixed offsets with structuresStefano Babic
This patch cleans driver code replacing all accesses to registers with fixed offsets with a corresponding structure. Signed-off-by: Stefano Babic <sbabic@denx.de>
2011-02-02SPI: mxc_spi: add SPI clock calculation and setup to the driverAnatolij Gustschin
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. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Stefano Babic <sbabic@denx.de>
2011-02-02SPI: mxc_spi: fix swapping bug and add missing swapping in unaligned rx caseAnatolij Gustschin
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.

2011-02-02Add basic support for Freescale's mc9sdz60Stefano Babic

2011-02-02I2C: mxc_i2c: address failure with mx35 processorStefano Babic
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.

2011-01-21Cleanup .boards.depend when using an objtreeLoïc Minier

2011-01-21Don't add symlink in srctree when using an objtreeLoïc Minier
When building with srctree != objtree, the build creates arch/soc/cpu specific symlinks in the source tree. This means that the same source tree can't be used for multiple builds at the same time. Also, these symlinks in the source tree are only cleaned up if one passes the same O= to distclean. When srctree != objtree, mkconfig creates an $objtree/include2 directory in the objtree to host the asm -> arch/$arch/include/asm symlink so that "#include <asm>" can be used. But it also creates another identical symlink in $objtree/include. Then, mkconfig creates two symlinks: $objtree/include/asm/arch -> arch/$arch/include/asm/arch-$cpu (or $soc) $objtree/include/asm/proc -> arch/$arch/include/asm/proc-armv (on arm) but because $objtree/include/asm points at $srctree already, the two symlinks are created under $srctree. To fix this, create a real $objtree/include/asm directory, instead of a symlink. Update cleanup code accordingly. Signed-off-by: Loïc Minier <loic.minier@linaro.org>

2011-01-19mpc85xx: Enable unique mode registers and dynamic ODT for DDR3York Sun
Added fsl_ddr_get_version() function to for DDR3 to poll DDRC IP version (major, minor, errata) to determine if unique mode registers are available. If true, always use unique mode registers. Dynamic ODT is enabled if needed. The table is documented in doc/README.fsl-ddr. This function may also need to be extend for future other platforms if such a feature exists. Enable address parity and RCW by default for RDIMMs. Change default output driver impedance from 34 ohm to 40ohm.
