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: NMike Frysinger <vapier@gentoo.org>

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: NMike Frysinger <vapier@gentoo.org>

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: NMike Frysinger <vapier@gentoo.org>

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: NMike Frysinger <vapier@gentoo.org>

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 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.

The previous code waited 1000us before checking i2c status. Measurement shows i2c is usually ready in under 50us. Change the polling interval to 15us, loop 6,667 times to keep the polling timeout constant at 100ms.

Move machine specific code to smdk6400. Some board use OneNAND instead of NAND. Some register MP0_CS_CFG[5:0] are controled by both h/w and s/w. So it's better to use macro instead of hard-coded value. Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com>

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.

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.
