| * | mtd core: call driver write function with complete bufferSascha Hauer2012-12-071-53/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mtd->write is supposed to loop around pages internally, no need to do this in mtd_write. This fixes a huge write performance drop with the m25p80 driver when it was converted to a mtd driver recently. Since mtd->writesize is 1 for this driver mtd_write ended up doing single byte writes on the flash. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | mtd nand: allow partial page writesSascha Hauer2012-12-071-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The nand layer handles partial page writes just fine. If the start or end of the data is not page aligned, the nand layer will copy the data to a temporary page buffer. Remove the check which disallows partial page writes since this is what we want to do on barebox when for example an image is written to nand which is not padded to page size.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the built-in RTC in the i.MX28 is programmed to wake-up the SoC, the RTC reports two events: RST and WAKE. RST is okay in this case, because the PMIC was really powered down. But the real event is the WAKE from the RTC and should have precedence over the RST event. So, report the WAKE event for this special case. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This controller needs some i.MX specific setup and some SoC specific setting outside the controller itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we only support oldschool IDE SFF devices. This is done by registering a register layout struct and everything else is done by the generic IDE SFF driver. Since modern ATA devices still use ATA, but not the SFF interface anymore, split out the IDE SFF support to a separate file to allow for other types of ata interfaces.
