* nand: mxc: Use appropriate page number in syndrome functionsBenoît Thébaudeau2013-04-12-3/+3
| | | | | | | | | | | The syndrome functions should use the page number passed as argument instead of the page number saved upon NAND_CMD_READ0. This does not make any difference if the NAND_NO_AUTOINCR option is set, but otherwise this fixes accesses to the wrong pages.

* mtd: nand: mxc_nand: Fix is_16bit_nand()Fabio Estevam2013-04-12-34/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently is_16bit_nand() is a per SoC function and it decides the bus nand width by reading some boot related registers. This method works when NAND is the boot medium, but does not work if another boot medium is used. For example: booting from a SD card and then using NAND to store the environment variables, would lead to the following error: NAND bus width 16 instead 8 bit No NAND device found!!! 0 MiB Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width. If it is defined in the board file, then consider 16-bit NAND bus-width, otherwise assume 8-bit NAND is used. This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which states: nand-bus-width : 8 or 16 bus width if not present 8 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Reviewed-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>

Therefore, disable the feature for now, until the driver adds the support. One usecase which is broken because of this feature is that Ether gadget stops working in Fullspeed mode (by un-defining CONFIG_USB_GADGET_DUALSPEED) After desabled this feature, MUSB driver send packets in proper size (no more than 64 bytes) in Fullspeed mode.

For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg (ECSPIx_CONGREG) the i.MX6 technical reference manual states: -- cut -- ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block and resets the internal logic with the exception of the ECSPI_CONREG. -- cut -- Note the exception mentioned: The CONREG itself isn't reset. Fix this by manually writing the reset value 0 to the whole register. This sets the EN bit to zero, too (i.e. includes the old ~MXC_CSPICTRL_EN). 2. We want to reset the whole SPI block here. So it makes no sense to first read the old value of the CONREG and write it back, later. This will give us the old (historic/random) value of the CONREG back. And doesn't reset the CONREG. To get a clean CONREG after the reset of the block, too, don't use the old (historic/random) value of the CONREG while doing the reset. And read the clean CONREG after the reset. This was found while working on a SPI boot device where the i.MX6 boot ROM has already initialized the SPI block. The initialization by the boot ROM might be different to what the U-Boot driver wants to configure. I.e. we need a clean reset of SPI block, including the CONREG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maximum bus width supported by some i.MX6 boards is not 8bit like others. In case where both host controller and card support 8bit transfers, they agree to communicate on 8bit interface while some boards support only 4bit interface. Due to this reason the mmc 8bit default mode fails on these boards. To rectify this, define maximum bus width supported by these boards (4bit). If max_bus_width is not defined, it is 0 by default and 8bit width support will be enabled in host capabilities otherwise host capabilities are modified accordingly. It is tested with a MMCplus card.

Workarounds are implemented for: * Register writes can't be too close to each-other in time, or they will be lost. * Register accesses must all be 32-bit, so implement custom accessors. This code was extracted from: git://github.com/gonzoua/u-boot-pi.git master which was created by Oleksandr Tymoshenko. Portions of the code there were obviously based on the Linux kernel at: git://github.com/raspberrypi/linux.git rpi-3.6.y commit f5b930b "Main bcm2708 linux port" signed-off-by Dom Cobley. swarren changed the following for upstream: * Removed hack udelay()s in bcm2835_sdhci_raw_writel(); setting SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues. * Remove register logging from read*/write* functions. * Sort out confusion with min/max_freq values passed to add_sdhci(). * Use more descriptive variable names and calculations in IO accessors. * Simplified and commented twoticks_delay calculation. * checkpatch fixes.

| * | | video: add a driver for the bcm2835Stephen Warren2013-03-20-0/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware running on the bcm2835 SoC's VideoCore CPU manages the display controller. Add a simple "LCD" driver that communicates with the firmware using the property mailbox protocol. This configures the display and frame-buffer to match whatever physical resolution the firmware chosen when booting, which is typically the native resolution of the attached display device, presumably unless otherwise specified in config.txt on the boot media. Enable this driver in the Raspberry Pi board configuration. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Anatolij Gustschin <agust@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This SPI controller can only write 64 bytes at a time. Add this restriction in so that 'sf write' works correct for blocks larger than 64 bytes. Signed-off-by: Simon Glass <sjg@chromium.org>
