* mtd: nand: denali: remove unused struct member totalblks, blksperchipMasahiro Yamada2016-11-191-2/+0
| | | | | | | | | | The denali->blksperchip is set, but not referenced any more. The denali->totalblks is used only for calculating denali->blksperchip. Both of them are unneeded.

* mtd: nand: denali: remove detect_partition_feature()Masahiro Yamada2016-11-191-9/+0
| | | | | | | | | | | | | | | | The denali->fwblks is set by detect_partition_feature(), but it is not referenced from anywhere. That means the struct member fwblks and the whole of detect_partition_feature() are unneeded. The comment block implies this function is only for Intel platforms. I found drivers/staging/spectra used to exist, but it was deleted by commit be7f39c5ecf5 ("Staging: delete spectra driver") 5 years ago. So, I guess nobody would need this function any more.

* mtd: nand: denali: remove unused struct member denali_nand_info::idxMasahiro Yamada2016-11-191-1/+0
| | | | | | | | | | | | The struct member "idx" was used as an index for debug_array long ago, but the DEBUG_DENALI feature was removed by commit 7cfffac06ca0 ("nand/denali: use dev_xx debug function to replace nand_dbg_print and some printk"). Since then, this has been only initialized, but never referenced.

* mtd: denali: fix include guard and license block of denali.hMasahiro Yamada2014-09-171-23/+4
| | | | | | | | | | It looks like this header file is a concatenation of two headers. Anyway, the include guard should be renamed and placed at the correct postion and the license block in the middle should be deleted.

* mtd: denali: kill the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZEHuang Shijie2014-01-111-3/+1
| | | | | | | | | | | | | | | | | | This patch kills the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE by the following way: 1.) change the @buf field of nand_buf{} from an array to a pointer. also remove the DENALI_BUF_SIZE macro. 2.) Before we call the nand_scan_ident, we allocate a temporary buffer whose size is PAGE_SIZE. 3.) After we finish the nand_scan_ident, we have already getten the page size and oob size. We will allocate the right buffer size again.

* mtd: denali: add a DT driverDinh Nguyen2012-11-151-0/+1
| | | | | | | | | Add a device tree version of the Denali NAND driver. Based on an original patch from Jamie Iles to add a MMIO version of this driver. Signed-off-by: Dinh Nguyen <dinguyen@altera.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
* mtd: denali: split the generic driver and PCI layerDinh Nguyen2012-11-151-0/+4
| | | | | | | | | | The Denali controller can also be found in SoC devices attached to a simple bus. Move the PCI specific parts into denali_pci so that we can add a denali_dt that uses the same driver but for a device tree driver instead of a PCI based device.

* mtd: denali: remove nearly-duplicated register definitionsJamie Iles2011-05-251-314/+57
| | | | | | | | | | | The controller has interrupt enable/status register pairs for each bank (along with ECC and status registers) that differ only in address offset. Rather than providing definitions for each register, make the address a macro so that it scales for devices with different numbers of banks.
