2011-07-01Makefile: need to remove generated u-boot-nand_spl.ldsKumar Gala
On MPC85xx based NAND_SPL builds we generate a u-boot-nand_spl.lds based on output from preprocessor. We where never removed it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Scott Wood <scottwood@freescale.com>
2011-07-01NAND: Add 16bit NAND support for the NDFCAlex Waterman
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>
2011-07-01cmd_nand: add nand write.trimffs commandBen Gardiner
Add another nand write. variant, trimffs. This command will request of nand_write_skip_bad() that all trailing all-0xff pages will be dropped from eraseblocks when they are written to flash as-per the reccommended behaviour of the UBI FAQ [1]. The function that implements this timming is the drop_ffs() function by Artem Bityutskiy, ported from the mtd-utils tree.

2011-07-01nand_util: drop trailing all-0xff pages if requestedBen Gardiner
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>
2011-07-01nand_util: treat WITH_YAFFS_OOB as a modeBen Gardiner
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.

2011-07-01nand_util: convert nand_write_skip_bad() to flagsBen Gardiner
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>

2011-06-29cfi_flash: reverse geometry for newer STM partsMike Frysinger
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 ...
