* Blackfin: audit UART for all known anomaliesMike Frysinger2009-04-06-2/+21
| | | | | | | There is no code change here, just new comments, but this keeps me from having to do another audit from scratch in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add check for anomaly 05000362Mike Frysinger2009-04-06-0/+9
| | | | | | | | | | | | | | | DESCRIPTION: The column address width settings for banks 2 and 3 are misconnected in the SDRAM controller. Accesses to bank 2 will result in an error if the Column Address Width for bank 3 (EB3CAW ) is not set to be the same as that of bank 2. WORKAROUND: If using bank 2, make sure that banks 2 and 3 have the same column address width settings in the EBIU_SDBCTL register. This must be the case regardless of whether or not bank 3 is enabled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: add workaround for anomaly 05000242Mike Frysinger2009-04-06-1/+1
| | | | | | | | | | | | | DESCRIPTION: If the DF bit is set prior to a hardware reset, the PLL will continue to divide CLKIN by 2 after the hardware reset, but the DF bit itself will be cleared in the PLL_CTL register. WORKAROUND: Reprogram the PLL with DF cleared if the desire is to not divide CLKIN by 2 after reset. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add workaround for anomaly 05000171Mike Frysinger2009-04-06-0/+4
| | | | | | | | | | | | | DESCRIPTION: The Boot ROM is executed at power up/reset and changes the value of the SICA_IWR registers from their default reset value of 0xFFFF, but does not restore them. WORKAROUND: User code should not rely on the default value of these registers. Set the desired values explicitly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: nand: flush peripheral before polling itGraf Yang2009-04-06-0/+1
| | | | | | | | | | We need to make sure the data written to the nand flash controller makes it there before we start polling its status register. Otherwise, we may get stale data and return before the controller is actually ready.

* Blackfin: spi: make cs deassert function deterministicTodor I Mollov2009-04-06-1/+15
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | imx31_phycore_eet is a variant of the imx31_phycore board with a few extensions, which justifies a separate entry in the MAINTAINERS list, whereas normally all entries sharing a single configuration file and a board/ directory have only one entry in MAINTAINERS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now UBIFS is supported by u-boot. If we ever decide to change the media format, then people will have to upgrade their u-boots to mount new format images. However, very often it is possible to preserve R/O forward-compatibility, even though the write forward-compatibility is not preserved. This patch introduces a new super-block field which stores the R/O compatibility version.
