2009-06-12mtd: Update MTD infrastructure to support 64bit device sizeStefan Roese
This patch brings the U-Boot MTD infrastructure in sync with the current Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size support and a resync of the mtdpart.c file which has seen multiple fixes meanwhile.

2009-06-12mtd: Add MTD concat support to concatenate multiple MTD NOR devicesStefan Roese
This patch adds concatenation support to the U-Boot MTD infrastructure. By enabling CONFIG_MTD_CONCAT this MTD CFI wrapper will concatenate all found NOR devices into one single MTD device. This can be used by e.g by UBI to access a partition that spans over multiple NOR chips. Signed-off-by: Stefan Roese <sr@denx.de>
2009-06-12ZOOM2 Add serial support.Tom Rix
Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board. The default serial is from the USB connector on left side of the debug board. The USB connector will produce 2 of the 4 UARTS. On your host pick the first enumeration. The details of the setting of the serial gpmc setup are not available. The values were provided by another party. The serial port set up is the same with Zoom1. Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow. The kernel bootargs are console=ttyS3,115200n8 Signed-off-by: Tom Rix <Tom.Rix@windriver.com>

2009-06-12video: Add an option to skip video initializationWolfgang Denk
This patch adds an option to skip the video initialization on for all video drivers. This is needed for the CPCI750 which can be built as CPCI host and adapter/target board.

2009-06-12i2c: Update references to individual i2c commandsPeter Tyser
The individual i2c commands imd, imm, inm, imw, icrc32, iprobe, iloop, and isdram are no longer available so all references to them have been updated to the new form of "i2c <cmd>". Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-06-12i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser
New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.

2009-06-08ppc4xx/net: Fix MDIO clock setupFelix Radensky
This patch fixes MDIO clock setup in case when OPB frequency is 100MHz. Current code assumes that the value of sysinfo.freqOPB is 100000000 when OPB frequency is 100MHz. In reality it is 100000001. As a result MDIO clock is set to incorrect value, larger than 2.5MHz, thus violating the standard. This in not a problem on boards equipped with Marvell PHYs (e.g. Canyonlands), since those PHYs support MDIO clocks up to 8.3MHz, but can be a problem for other PHYs (e.g. Realtek ones).

2009-06-08SMC911x driver fixed for NFS bootManikandan Pillai
eth_halt() function in the smc911x drivers used to call the smc911x_reset() function. eth_halt() used to be called after tftp transfers. This used to put the ethernet chip in reset while the linux boots up resulting in the ethernet driver not coming up. NFS boot used to fail as a result. This patch calls smc911x_shutdown() instead of smc911x_reset(). Some comments received has also been fixed.

2009-06-08Add config option for disabling DM9000-SROM support.Remy Bohmer
Some boards do not have SROM support for the DM9000 network adapter. Instead of listing these board names in the driver code, make this option configurable from the board config file. It also removes a build warning for the at91sam9261ek board: 'dm9000x.c:545: warning: 'read_srom_word' defined but not used' And it repaires the trizepsiv board build which was broken around the same routines Signed-off-by: Remy Bohmer <linux@bohmer.net> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

2009-06-04Redundant Environment: protect full sector sizeWolfgang Denk
Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

2009-06-02mmc: fix response decoding on little endianRabin Vincent
The mmc code defines the response as an array of chars. However, it access the response bytes both as (i) an array of four uints (with casts) and (ii) as individual chars. The former case is used more often, including by the driver when it assigns the response. The char-wise accesses are broken on little endian systems because they assume that the bytes in the uints are in big endian byte order. This patch fixes this by changing the response to be an array of four uints and replacing the char-wise accesses with equivalent uint-wise accesses. Signed-off-by: Rabin Vincent <rabin@rab.in>

2009-04-06Blackfin: spi: make cs deassert function deterministicTodor I Mollov
Blackfin SPI driver was not driving the SPI chip-select high before putting the chip-select signals into tri-state mode. This is probably something that slipped by unnoticed in most designs. If the signals are put directly into a tri-state mode, then the board is relying on the pull-up resistors to pull up the chip-select before the next transaction. Most of the time this is fine, except when you have two transactions that follow each other very closely, such as the flash erase and read status register commands. In this case I was seeing a 500ns separation between the transactions. In my setup, with a 10kOhm pull-up, it would meet timing spec about half the time and resulted in intermittent errors. (A stronger pull up would fix this, but our design is targeted for low power consumption and a 3.3kOhm @ 3.3v is 3.3mW of needless power consumption.) I modified the spi_cs_deactivate() function in bfin_spi.c to drive the chip-selects high before putting them into tri-state. For me, this resulted in a rise time of 5ns instead of the previous rise time of about 1us, and fully satisfied the timing spec of the chip.
