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.

2009-04-05ARM: add the imx31_phycore_eet target to MAINTAINERSGuennadi Liakhovetski
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.

2009-04-04UBI/cfi-mtd: Fix mtd name for multiple chipsAndreas Huber
On platforms with multiple NOR chips, currently only the first one can be selected using the "ubi part" command. This patch fixes this problem by using different names for the NOR "mtd devices". It also changes the name of the NOR MTD device from "cfi-mtd" to "norX" (X indexing the device numer) to better match the mtdparts defaults.

2009-04-04UBIFS: add R/O compatibilityArtem Bityutskiy
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.
