* atmel_nand: don't require CONFIG_SYS_NAND_ENABLE_PINmichael2011-04-01-0/+2
| | | | | | | | | | | | If NCE is hooked up to NCS3, we don't need to (and can't) explicitly set the state of the NCE pin. Instead, the controller asserts it automatically as part of a command/data access. Only "CE don't care"-type NAND chips can be used in this manner.

* NAND: add support for reading ONFI page tableFlorian Fainelli2011-04-01-49/+144
| | | | | | | | | | | | This patch adds support for reading an ONFI page parameter from a NAND device supporting it. If this is the case, struct nand_chip onfi_version member contains the supported ONFI version, 0 otherwise. This allows NAND drivers past nand_scan_ident to set the best timings for the NAND chip.

| * powerpc/85xx: Handle PCIe initialization requires for P1021 class SoCsPrabhakar Kushwaha2011-03-29-0/+7
| | | | | | | | | | | | | | | | | | | | The P1011, P1012, P1015, P1016, P1020, P1021, P1024, & P1025 SoCs require that we initialize the SERDES registers if the lanes are configured for PCIe. Additionally these devices PCIe controller do not support ASPM and we have to explicitly disable it.

* | cfi_flash: fix bug with flash banks with different sector numbersMartin Krause2011-03-28-0/+5
|/ | | | | | | | | | | | | | | The function find_sector() does not take into account if the flash bank has changed since the last call. This could lead to illegal accesses inside and beyond the flash_info_t info strcture. For example if the current flash bank has less sectors than the last used flash bank. This patch adds two cheks. One that insures, that the current sector does not exceed the allowed maximum (which is always a good idea). And one that checks if the current access is to the same flash bank as the last access. If not, the search loop will start with sector 0. Signed-off-by: Martin Krause <martin.krause@tqs.de> Signed-off-by: Stefan Roese <sr@denx.de>

* S5P: mmc: Resolved interrupt error during mmc_initChander Kashyap2011-03-27-1/+1
| | | | | | | | | | | | Blocksize was hardcoded to 512 bytes. But the blocksize varies depeding on various mmc subsystem commands (between 8 and 512). This hardcoding was resulting in interrupt error during data transfer. It is now calculated based upon the request sent by mmc subsystem.

| | | | | | | | | | | | | | | | | | | | | | | | - Timeout counter value is set as DTOCV bits in SYSCTL register For counter value set as timeout, Timeout period = (2^(timeout + 13)) SD Clock cycles - As per 4.6.2.2 section of SD Card specification v2.00, host should cofigure timeout period value to minimum 0.25 sec. - Number of SD Clock cycles for 0.25sec should be minimum (SD Clock/sec * 0.25 sec) SD Clock cycles = (mmc->tran_speed * 1/4) SD Clock cycles - Calculating timeout based on (2^(timeout + 13)) >= mmc->tran_speed * 1/4 Taking log2 both the sides and rounding up to next power of 2 => timeout + 13 = log2(mmc->tran_speed/4) + 1 Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com> Acked-by: Mingkai Hu <Mingkai.Hu@freescale.com> Tested-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* USB-CDC: handle interrupt after dropped pullupVitaly Kuzmichev2011-02-19-0/+7
| | | | | | | | | | | | Disconnecting USB gadget with pending interrupt may cause its wrong handling in the next time when interface will be started again (especially actual for RNDIS). This interrupt may force the gadget to queue unexpected response before setup stage. Despite the fact that such interrupt handled after dropped pullup also may add pending response, this will not bring to any issues due to usb_ep_disable (which clears the queue) called on gadget unregistering.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
