* FSL LAW: Add new interface to use the last free LAWKumar Gala2008-06-11-0/+20
| | | | | | | | LAWs have the concept of priority so its useful to be able to allocate the lowest (highest number) priority. We will end up using this with the new DDR code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx/86xx: Move to dynamic mgmt of LAWsKumar Gala2008-06-11-127/+124
| | | | | | | | | | | With the new LAW interface (set_next_law) we can move to letting the system allocate which LAWs are used for what purpose. This makes life a bit easier going forward with the new DDR code.

* FSL LAW: Keep track of LAW allocationsKumar Gala2008-06-11-25/+59
| | | | | | | | | | | | | | | Make it so we keep track of which LAWs have allocated and provide a function (set_next_law) which can allocate a LAW for us if one is free. In the future we will move to doing more "dynamic" LAW allocation since the majority of users dont really care about what LAW number they are at. Also, add CONFIG_MPC8540 or CONFIG_MPC8560 to those boards which needed them Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andy Fleming <afleming@freescale.com>

* TQM85xx: Change memory map to support Flash memory > 128 MiBWolfgang Grandegger2008-06-11-11/+167
| | | | | | | | | | | | | | | | | Some TQM85xx boards could be equipped with up to 1 GiB (NOR) Flash memory. The current memory map only supports up to 128 MiB Flash. This patch adds the configuration option CONFIG_TQM_BIGFLASH. If set, up to 1 GiB flash is supported. To achieve this, the memory map has to be adjusted in great parts (for example the CCSRBAR is moved from 0xE0000000 to 0xA0000000). If you want to boot Linux with CONFIG_TQM_BIGFLASH set, the new memory map also has to be considered in the kernel (changed CCSRBAR address, changed PCI IO base address, ...). Please use an appropriate Flat Device Tree blob (tqm8548.dtb). Signed-off-by: Martin Krause <martin.krause@tqs.de> Signed-off-by: Wolfgang Grandegger <wg@grandegger.com>
* TQM85xx: NAND support via local bus UPMBWolfgang Grandegger2008-06-11-8/+558
| | | | | | | | | | | | | | | | | | | This patch adds support for NAND FLASH on the TQM8548. It is disabled by default and can be enabled for the TQM8548 modules. It is now based on the re-written FSL NAND UPM driver. A patch has been posted earlier today with the subject: "NAND FSL UPM: driver re-write using the hwcontrol callback" Note that the R/B pin is not supported by that module requiring to use the specified maximum delay time. Note: With NAND support enabled the size of the U-Boot image exceeds 256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk, doubling the image size :-(.

* NAND FSL UPM: driver re-write using the hwcontrol callbackWolfgang Grandegger2008-06-10-83/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a re-write of the NAND FSL UPM driver using the more universal hwcontrol callback (instead of the cmdfunc callback). Here is a brief list of furher modifications: - For the time being, the UPM setup writing the UPM array has been removed from the driver and must now be done by the board specific code. - The bus width definition in "struct fsl_upm_nand" is now in bits to comply with the corresponding Linux driver and 8, 16 and 32 bit accesses are supported. - chip->dev_read is only set if fun->dev_ready != NULL, which is required for boards not connecting the R/B pin. - A few issue have been fixed with MxMR bit manipulation like in the corresponding Linux driver. Note: I think the "io_addr" field of "struct fsl_upm" could be removed as well, because the address is already determined by "nand->IO_ADDR_[RW]", but I'm not 100% sure. This patch has been tested on a TQM8548 modules with the NAND chip Micron MT29F8G08FABWP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On AD7414 the first value upon bootup is not read correctly. This is most likely because of the 800ms update time of the temp register in normal update mode. To get current values each time we issue the "dtt" command including upon powerup we switch into one-short mode. This patch fixes the problem on AD7414 equipped boards (Sequoia, Canyonlands etc), that temp value printed in the bootup log was incorrect. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a driver for the SPI controller found on most AT91 and AVR32 chips, implementing the new SPI API. Changed in v4: - Update to new API - Handle zero-length transfers appropriately. The user may send a zero-length SPI transfer with SPI_XFER_END set in order to deactivate the chip select after a series of transfers with chip select active. This is useful e.g. when polling the status register of DataFlash. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * SPI API improvementsHaavard Skinnemoen2008-06-03-209/+584

Instead of the spi_chipsel table, each board that wants to use SPI gets to implement three hooks: * spi_cs_activate(): Activates the chipselect for a given slave * spi_cs_deactivate(): Deactivates the chipselect for a given slave * spi_cs_is_valid(): Determines if the given bus/chipselect combination can be activated. Not all drivers may need those extra functions however. If that's the case, the board code may just leave them out (assuming they know what the driver needs) or rely on the linker to strip them out (assuming --gc-sections is being used.) To set up communication parameters for a given slave, the driver needs to call spi_setup_slave(). This returns a pointer to an opaque spi_slave struct which must be passed as a parameter to subsequent SPI calls. This struct can be freed by calling spi_free_slave(), but most driver probably don't want to do this. Before starting one or more SPI transfers, the driver must call spi_claim_bus() to gain exclusive access to the SPI bus and initialize the hardware. When all transfers are done, the driver must call spi_release_bus() to make the bus available to others, and possibly shut down the SPI controller hardware. spi_xfer() behaves mostly the same as before, but it now takes a spi_slave parameter instead of a spi_chipsel function pointer. It also got a new parameter, flags, which is used to specify chip select behaviour. This may be extended with other flags in the future. This patch has been build-tested on all powerpc and arm boards involved. I have not tested NIOS since I don't have a toolchain for it installed, so I expect some breakage there even though I've tried fixing up everything I could find by visual inspection. I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and DataFlash drivers posted as a follow-up. I'd like some help testing other boards that use the existing SPI API. But most of all, I'd like some comments on the new API. Is this stuff usable for everyone? If not, why? Changed in v4: - Build fixes for various boards, drivers and commands - Provide common struct spi_slave definition that can be extended by drivers - Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate - Make default bus and mode build-time configurable - Override default SPI bus ID and mode on mx32ads and imx31_litekit. Changed in v3: - Add opaque struct spi_slave for controller-specific data associated with a slave. - Add spi_claim_bus() and spi_release_bus() - Add spi_free_slave() - spi_setup() is now called spi_setup_slave() and returns a struct spi_slave - soft_spi now supports four SPI modes (CPOL|CPHA) - Add bus parameter to spi_setup_slave() - Convert the new i.MX32 SPI driver - Convert the new MC13783 RTC driver Changed in v2: - Convert the mpc8xxx_spi driver and the mpc8349emds board to the new API.
