* ARMV7: OMAP: I2C driver: Restructure i2c_read_byte functionSteve Sakoman2010-10-20-39/+37
| | | | | | | | This patch removes the "magic number" delays and instead monitors state changes in the status register bits. Signed-off-by: Steve Sakoman <steve.sakomanlinaro.org> Tested-by: Heiko Schocher <hs@denx.de>
* ARMV7: OMAP: I2C driver: Use same timeout value as linux kernel driverSteve Sakoman2010-10-20-6/+8
| | | | | | | | | | This patch matches the poll interval (1 millisecond) and timeout (1 second) used in the linux driver. It also adds a return value of 0 in the event of a timeout error and cleans up some formatting errors in that section of the code.

* USB: sync Queue Element Transfer Descriptor against EHCI specWolfgang Denk2010-10-20-5/+10
| | | | | | | | | | | | | | | | | | | Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too. This fixes some nasty memory corruption problems.

* | | ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boardsStefan Roese2010-10-13-0/+9
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Call watchdog_reset() upon newline. This is done here in putc since the environment code uses a single puts() to print the complete envrironment upon "printenv". So we can't put this watchdog call in puts(). This is needed for boards with a very short watchdog timeout, like the lwmon5 with a 100ms timeout. Without this patch this board resets in the commands with long outputs, like "printenv" or "fdt print". Note that the image size is not increased with this patch when CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler optimizes this additional code away.

| | * | MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51Stefano Babic2010-09-30-41/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual SPI driver for i.MX31 and i.MX51 controller use a wrong byte ordering, because it is supposed to work only with Freescale's devices, as the Power Controllers (PMIC). The driver is not suitable for general purposes, because the buffers passed to spi_xfer must be 32-bit aligned, as it is used mainly to send integer to PMIC devices. The patch drops any kind of limitation and makes the driver useful with devices controlled sending commands composed by single bytes (or by a odd number of bytes), such as spi flash, sensor, etc. Because the byte ordering is changed, any current driver using this controller must be adapted, too.

As reported by the manual, the meaning of the SSPOL inside the configuration register is the same as reported by SPI specification (0 if low in idle, 1 is high on idle). The driver inverts this logic. Because this patch sets the logic as specified, it is required to clear the CPOL bit in the configuration file to adapt to the correct logic.

All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.
