* General help message cleanupWolfgang Denk2009-06-12-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
* mtd: Introduce CONFIG_MTD_DEVICE to select compilation of mtdcore.oStefan Roese2009-06-12-3/+4
| | | | | | | | | | | | | This new define enables mtdcore.c compilation and with this we can select the MTD device infrastructure needed for the reworked mtdparts command. We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above) for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

* mtd: Update MTD infrastructure to support 64bit device sizeStefan Roese2009-06-12-274/+229
| | | | | | | | | | | 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.

* mtd: Add MTD concat support to concatenate multiple MTD NOR devicesStefan Roese2009-06-12-1/+886
| | | | | | | | | 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>
* ZOOM2 Add serial support.Tom Rix2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | 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.

* | ppc4xx/net: Fix MDIO clock setupFelix Radensky2009-06-08-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * mmc: fix response decoding on little endianRabin Vincent2009-06-02-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | Redundant Environment: protect full sector sizeWolfgang Denk2009-06-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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