| * 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.

* UBI/cfi-mtd: Fix mtd name for multiple chipsAndreas Huber2009-04-04-1/+3
| | | | | | | | | | | | | 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.

* mflash: Initial mflash supportunsik Kim2009-04-03-2/+730
| | | | | | | | | | | | | | | | | | | | Mflash is fusion memory device mainly targeted consumer eletronic and mobile phone. Internally, it have nand flash and other hardware logics and supports some different operation (ATA, IO, XIP) modes. IO mode is custom mode for the host that doesn't have IDE interface. (Many mobile targeted SoC doesn't have IDE bus) This driver support mflash IO mode. Followings are brief descriptions about IO mode. 1. IO mode based on ATA protocol and uses some custom command. (read confirm, write confirm) 2. IO mode uses SRAM bus interface. Signed-off-by: unsik Kim <donari75@gmail.com>

| * Noisily disable the legacy NAND subsystem.Scott Wood2009-04-03-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Legacy NAND is marked for feature removal after April 2009 (i.e. this upcoming release). There are still several boards that reference it (though many do so only for disk-on-chip support which has been silently disabled for a while now). These boards will now fail to build with #error, though the code is still there if the user removes #error. The plan is to remove the code outright in the next release, along with any board code that refers to it (such as board/esd/common/auto_update.c). Also, remove the legacy NAND API description from README.nand. Signed-off-by: Scott Wood <scottwood@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I can't find anywhere in the datasheet that says the status register needs 3 dummy bytes sent to it before being able to read back the first real result. Tests on a Blackfin board show that after writing the opcode, the status register starts coming back immediately. So only write out the read status register opcode before polling the result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since timeouts are only hit when there is a problem in the system, we don't want to prematurely timeout on a functioning setup. Thus having low timeouts (in milliseconds) doesn't gain us anything in the production case, but rather increases likely hood of causing problems where none otherwise exist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SPI flash drivers like to have extended id information available (like the spansion flash), so rather than making it re-issue the ID cmd to get at the last 2 bytes, have the common code read 5 bytes rather than just 3. This also matches the Linux behavior where it always reads 5 id bytes from all flashes.
