* sf: unify write enable commandsMike Frysinger2011-07-26-8/+16
| | | | | | | Every spi flash uses the same write enable command, so unify this in the common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* NAND: Add 16bit NAND support for the NDFCAlex Waterman2011-07-01-4/+29
| | | | | | | | | | | | | | | | | | | This patch adds support for 16 bit NAND devices attached to the NDFC on ppc4xx processors. Two config entries were added: CONFIG_SYS_NDFC_16 - Setting this tells the NDFC that a 16 bit device is attached. CONFIG_SYS_NDFC_EBC0_CFG - This is for the External Bus Controller configuration register. Also, a new ndfc_read_byte() function was added which does not first convert the data to little endian. The NAND SPL was also modified to do 16bit bad block testing when a 16 bit chip is being used. Signed-off-by: Alex Waterman <awaterman@dawning.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand_util: drop trailing all-0xff pages if requestedBen Gardiner2011-07-01-3/+37
| | | | | | | | | | | | | | | | | | | | Add a flag to nand_read_skip_bad() such that if true, any trailing pages in an eraseblock whose contents are entirely 0xff will be dropped. The implementation is via a new drop_ffs() function which is based on the function of the same name from the ubiformat utility by Artem Bityutskiy. This is as-per the reccomendations of the UBI FAQ [1] [1] http://www.linux-mtd.infradead.org/doc/ubi.html#L_flasher_algo Signed-off-by: Ben Gardiner <bengardiner@nanometrics.ca> CC: Artem Bityutskiy <dedekind1@gmail.com> Acked-by: Detlev Zundel <dzu@denx.de> CC: Scott Wood <scottwood@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand_util: treat WITH_YAFFS_OOB as a modeBen Gardiner2011-07-01-0/+3
| | | | | | | | | | | | | When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an operation which is mutually exclusive with the 'usual' way of writing. Add a check that client code does not specify WITH_YAFFS_OOB along with any other flags and add a comment indicating that the WITH_YAFFS_OOB flag should not be mixed with other flags.

* nand_util: convert nand_write_skip_bad() to flagsBen Gardiner2011-07-01-4/+4
| | | | | | | | | | | | | | | | | | | | | | In a future commit the behaviour of nand_write_skip_bad() will be further extended. Convert the only flag currently passed to the nand_write_ skip_bad() function to a bitfield of only one allocated member. This should avoid an explosion of int's at the end of the parameter list or the ambiguous calls like nand_write_skip_bad(info, offset, len, buf, 0, 1, 1); nand_write_skip_bad(info, offset, len, buf, 0, 1, 0); Instead there will be: nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB | WITH_OTHER); Signed-off-by: Ben Gardiner <bengardiner@nanometrics.ca> Acked-by: Detlev Zundel <dzu@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>

* cfi_flash: reverse geometry for newer STM partsMike Frysinger2011-06-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | For newer STM parts where CFI >= 1.1, there is a byte in the extended structure that declares the flash layout type (just like the AMD parts), so key off of that to find out when we need to reverse the geometry. This can be seen with M29W640 parts where U-Boot does: Bank # 1: CFI conformant FLASH (16 x 16) Size: 8 MB in 135 Sectors AMD Standard command set, Manufacturer ID: 0x20, Device ID: 0x22ED Erase timeout: 8192 ms, write timeout: 1 ms Buffer write timeout: 1 ms, buffer size: 16 bytes Sector Start Addresses: 20000000 RO 20002000 RO 20004000 RO 20006000 RO 20008000 RO 2000A000 RO 2000C000 RO 2000E000 RO 20010000 RO 20020000 RO ...

| | | | | | | | | | | | | I ran into a problem where the reset was failing except when I enabled debugging support.

* NAND: rearrange ONFI revision checking, add ONFI 2.3Florian Fainelli2011-04-15-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sync with Brian's patch on Linux in nand_flash_detect_onfi() commit b7b1a29d94c17e4341856381bccb4d17495bea60 Author: Brian Norris <computersforpeace@gmail.com> Date: Sun Dec 12 00:23:33 2010 -0800 mtd: nand: rearrange ONFI revision checking, add ONFI 2.3 In checking for the ONFI revision, the first conditional (for checking "unsupported" ONFI) seems unnecessary. All ONFI revisions should be backwards-compatible; even if this is not the case on some newer ONFI revision, it should simply fail the second version-checking if-else block (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we move our "unsupported" condition after having checked each bit field. Also, it's simple enough to add a condition for ONFI revision 2.3. Note that this does *NOT* mean we handle all new features of ONFI versions above 1.0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new member to struct spi_flash (u16 sector_size) and updates the spi flash drivers to start populating it. This parameter can be used by spi flash commands that need to round up units of operation to the flash's sector_size. Having this number in one place also allows duplicated code to be further collapsed into one common location (such as erase parameter and the detected message).

* cfi_flash: fix bug with flash banks with different sector numbersMartin Krause2011-03-28-0/+5
| | | | | | | | | | | | | | | The function find_sector() does not take into account if the flash bank has changed since the last call. This could lead to illegal accesses inside and beyond the flash_info_t info strcture. For example if the current flash bank has less sectors than the last used flash bank. This patch adds two cheks. One that insures, that the current sector does not exceed the allowed maximum (which is always a good idea). And one that checks if the current access is to the same flash bank as the last access. If not, the search loop will start with sector 0. Signed-off-by: Martin Krause <martin.krause@tqs.de> Signed-off-by: Stefan Roese <sr@denx.de>
