* mtd: nand: Add+use mtd_to/from_nand and nand_get/set_controller_dataScott Wood2016-06-03-11/+11
| | | | | | | | | These functions are part of the Linux 4.6 sync. They are being added before the main sync patch in order to make it easier to address the issue across all NAND drivers (many/most of which do not closely track their Linux counterparts) separately from other merge issues.

* nand: Remove CONFIG_MTD_NAND_VERIFY_WRITEPeter Tyser2015-03-30-18/+0
| | | | | | | | | The CONFIG_MTD_NAND_VERIFY_WRITE has been removed from Linux for some time and a more generic method of NAND verification now exists in U-Boot. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Tested-by: Heiko Schocher <hs@denx.de> Acked-by: Heiko Schocher <hs@denx.de>

* MPC85xx: remove support for TQM85xx boardsWolfgang Denk2012-10-05-5/+5
| | | | | | | | | | | | Due to grown code sizes the TQM85xx boards don't build any more with some older tool chains (like ELDK 4.2). As these boards have long reached EOL it seems a waste of effort trying to fix them. The vendor has agreed to drop support for them, too. So let's get rid of them.

* fsl_upm: Add MxMR/MDR synchronizationJohn Schmoller2010-12-13-0/+2
| | | | | | | | | | | | | | | | | According to Freescale reference manuals (eg section "13.4.4.2 Programming the UPMs" of the P4080 Reference Manual): "Since the result of any update to the MxMR/MDR register must be in effect before the dummy read or write to the UPM region, a write to MxMR/MDR should be followed immediately by a read of MxMR/MDR." The UPM on a custom P4080-based board did not work without performing a read of MxMR/MDR after a write.

* Add wait flags to support board/chip specific delaysWolfgang Grandegger2009-03-23-9/+28
| | | | | | | | | | | | | | The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.

* Add support for TQM-specific chip select logic to FSL-UPMWolfgang Grandegger2009-03-23-1/+4
| | | | | | | | | For the NAND chips on the TQM8548 modules, a special chip-select logic is used. It uses dedicated address lines to be set via UPM machine address register (mar). This patch adds such support to the FSL-UPM driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Add multi chip support to the FSL-UPM driverWolfgang Grandegger2009-03-23-8/+36
| | | | | | | | | | | This patch adds support for multi-chip NAND devices to the FSL-UPM driver. The "dev_ready" callback of the "struct fsl_upm_nand" is now called with the argument "chip_nr" to allow testing the proper chip select line. The NAND support of the MPC8360ERDK is updated as well. No other boards are currently using the FSL UPM driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

* NAND FSL UPM: driver re-write using the hwcontrol callbackWolfgang Grandegger2008-06-10-82/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a re-write of the NAND FSL UPM driver using the more universal hwcontrol callback (instead of the cmdfunc callback). Here is a brief list of furher modifications: - For the time being, the UPM setup writing the UPM array has been removed from the driver and must now be done by the board specific code. - The bus width definition in "struct fsl_upm_nand" is now in bits to comply with the corresponding Linux driver and 8, 16 and 32 bit accesses are supported. - chip->dev_read is only set if fun->dev_ready != NULL, which is required for boards not connecting the R/B pin. - A few issue have been fixed with MxMR bit manipulation like in the corresponding Linux driver. Note: I think the "io_addr" field of "struct fsl_upm" could be removed as well, because the address is already determined by "nand->IO_ADDR_[RW]", but I'm not 100% sure. This patch has been tested on a TQM8548 modules with the NAND chip Micron MT29F8G08FABWP. This patch is based on the following patches posted to this list a few minutes ago: PPC: add accessor macros to clear and set bits in one shot 83xx/85xx/86xx: add more MxMR local bus definitions Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Anton Vorontsov <avorontsov@ru.mvista.com>
