nand/davinci: make sure ECC calculation has really started

2010-09-13T19:43:05Z

Due to a register glitch (result code <4 might show up right after the start-calculation-bit was set), make sure the ECC has really started. See 1c3275b656045aff9a75bb2c9f3251af1043ebb3 in the kernel. Signed-off-by: Wolfram Sang Cc: Sandeep Paulraj

mtd: nand: supress 'unknown NAND' warning if no nand is found

2010-09-08T18:51:29Z

This printk was added recently and results in ugly output on systems with no NAND: NAND: nand_get_flash_type: unknown NAND device: Manufacturer ID: 0x00, Chip ID: 0x00 0 MiB instead of: NAND: 0 MiB Signed-off-by: Steve Sakoman Acked-by: Scott Wood Signed-off-by: Sandeep Paulraj

83xx/85xx/86xx: LBC register cleanup

2010-07-16T15:55:09Z

Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family. Signed-off-by: Becky Bruce Acked-by: Kim Phillips Signed-off-by: Kumar Gala

Blackfin: bfin_nand: convert to portmux framework

2010-07-13T21:50:49Z

Rather than bang MMRs directly, use the new portmux framework to handle the details. Signed-off-by: Mike Frysinger Acked-by: Scott Wood

mtd: nand_plat: add simple GPIO framework DEV_READY option

2010-07-08T21:52:12Z

Make it easy to use GPIOs for the DEV_READY pin by using the common GPIO framework. Also make the NAND_PLAT_INIT() define optional. Signed-off-by: Mike Frysinger Tested-by: Thomas Chou

NAND: add Toshiba TC58NVG0 identifier

2010-07-08T21:49:50Z

The Toshiba TC58NVG0* parts are 128Mbytes x 8 bits 3.3V parts with the 0xD1 identifier. Add these to the list of known devices IDs. Signed-off-by: Florian Fainelli

NAND: show manufacturer and device ID for unknown chips

2010-07-08T21:49:50Z

When the NAND part is not supported, it is useful to show the manufacturer and device ID to help debugging and reporting. Signed-off-by: Florian Fainelli Signed-off-by: Scott Wood

Blackfin: nand: drain the write buffer before returning

2010-05-26T22:59:13Z

The current Blackfin nand write function fills up the write buffer but returns before it has had a chance to drain. On faster systems, this isn't a problem as the operation finishes before the ECC registers are read, but on slower systems the ECC may be incomplete when the core tries to read it. So wait for the buffer to drain once we're done writing to it. Signed-off-by: Andrew Caldwell Signed-off-by: Mike Frysinger

at91: add hwecc method for nand

2010-03-23T19:29:09Z

This is a patch to use the hardware ECC controller of the AT91SAM9260 for the AT91 nand. Taken from the kernel 2.6.33. Signed-off-by: Nikolay Petukhov
