* Use strncmp() for the fdt commandGerald Van Baren2008-06-09-9/+7

* The fdt boardsetup command criteria was not uniqueGerald Van Baren2008-06-09-1/+2
| | | | | | | It was checking just for "b", which is not unique with respect to the "boot" command. Change to check for "boa"[rdsetup]. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
* Remove the deprecated CONFIG_OF_FLAT_TREEGerald Van Baren2008-06-09-472/+0
| | | | | | | Use CONFIG_OF_LIBFDT instead to support flattened device trees. It is cleaner, has better functionality, and is better supported. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
* Additional fix to readline_into_buffer() with CONFIG_CMDLINE_EDITING before ↵Peter Tyser2008-06-03-6/+0
| | | | | | | | | | | relocating Removed unneeded command line history initialization. Also, the original code would access the 'initted' variable before relocation to SDRAM which resulted in erratic behavior since the bss is not initialized when executing from flash.

* Add support for environment in SPI flashHaavard Skinnemoen2008-06-03-2/+136
| | | | | | | | | This is pretty incomplete...it doesn't handle reading the environment before relocation, it doesn't support redundant environment, and it doesn't support embedded environment. But apart from that, it does seem to work. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* SPI Flash: Add "sf" commandHaavard Skinnemoen2008-06-03-0/+192
| | | | | | | | This adds a new command, "sf" which can be used to manipulate SPI flash. Currently, initialization, reading, writing and erasing is supported. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* SPI API improvementsHaavard Skinnemoen2008-06-03-48/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch gets rid of the spi_chipsel table and adds a handful of new functions that makes the SPI layer cleaner and more flexible. 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.

* soft_i2c: Pull SDA high before readingHaavard Skinnemoen2008-06-03-0/+1
| | | | | | | | | | | | | Spotted by Dean Capindale. Systems that support open-drain GPIO properly are allowed provide an empty I2C_TRISTATE define. However, this means that we need to be careful not to drive SDA low when the slave is expected to respond. This patch adds a missing I2C_SDA(1) to read_byte() required to tristate the SDA line on systems that support open-drain GPIO. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

| | | | | | | | | If common.h isn't first we can get CONFIG_ options defined in the board config file ignored. This can cause an issue if any of those config options impact the size of types of data structures (eg CONFIG_PHYS_64BIT). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | The envcrc.c does sizeof(unsigned long) when calculating the crc, but this is done with the build toolchain instead of the target tool chain, so if the build is a 64bit system but the target is 32bits, the size will obviously be wrong.
