mtd: slram: use memremap() instead of ioremap()

2017-11-13T20:39:16+00:00

Convert slram to use memremap() to map the memory it uses to back an MTD device, as this is the proper interface for mapping memory. This change enables normal memory to be used to back an MTD device on arm64, as arm64 prevents ioremap() being used on normal memory.

Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6

2012-03-31T00:31:56+00:00

Pull MTD changes from David Woodhouse: - Artem's cleanup of the MTD API continues apace. - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst others. - More work on DiskOnChip G3, new driver for DiskOnChip G4. - Clean up debug/warning printks in JFFS2 to use pr_. Fix up various trivial conflicts, largely due to changes in calling conventions for things like dmaengine_prep_slave_sg() (new inline wrapper to hide new parameter, clashing with rewrite of previously last parameter that used to be an 'append' flag, and is now a bitmap of 'unsigned long flags'). (Also some header file fallout - like so many merges this merge window - and silly conflicts with sparse fixes) * tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6: (120 commits) mtd: docg3 add protection against concurrency mtd: docg3 refactor cascade floors structure mtd: docg3 increase write/erase timeout mtd: docg3 fix inbound calculations mtd: nand: gpmi: fix function annotations mtd: phram: fix section mismatch for phram_setup mtd: unify initialization of erase_info->fail_addr mtd: support ONFI multi lun NAND mtd: sm_ftl: fix typo in major number. mtd: add device-tree support to spear_smi mtd: spear_smi: Remove default partition information from driver mtd: Add device-tree support to fsmc_nand mtd: fix section mismatch for doc_probe_device mtd: nand/fsmc: Remove sparse warnings and errors mtd: nand/fsmc: Add DMA support mtd: nand/fsmc: Access the NAND device word by word whenever possible mtd: nand/fsmc: Use dev_err to report error scenario mtd: nand/fsmc: Use devm routines mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platform mtd: fsmc_nand: add pm callbacks to support hibernation ...

mtd: harmonize mtd_point interface implementation

2012-03-26T23:32:11+00:00

Some MTD drivers return -EINVAL if the 'phys' parameter is not NULL, trying to convey that they cannot return the physical address. However, this is not very logical because they still can return the virtual address ('virt'). But some drivers (lpddr) just ignore the 'phys' parameter instead, which is a more logical thing to do. Let's harmonize this and: 1. Always initialize 'virt' and 'phys' to 'NULL' in 'mtd_point()'. 2. Do not return an error if the physical address cannot be found. So as a result, all drivers will set 'phys' to 'NULL' if it is not supported. None of the 'mtd_point()' users use 'phys' anyway, so this should not break anything. I guess we could also just delete this parameter later. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: do not duplicate length and offset checks in drivers

2012-03-26T23:28:18+00:00

We already verify that offset and length are within the MTD device size in the MTD API functions. Let's remove the duplicated checks in drivers. This patch only affects the following API's: 'mtd_erase()' 'mtd_point()' 'mtd_unpoint()' 'mtd_get_unmapped_area()' 'mtd_read()' 'mtd_write()' 'mtd_panic_write()' 'mtd_lock()' 'mtd_unlock()' 'mtd_is_locked()' 'mtd_block_isbad()' 'mtd_block_markbad()' This patch adds a bit of noise by removing too sparse empty lines, but this is not too bad.

mtd: return error code from mtd_unpoint

2012-03-26T23:27:19+00:00

The 'mtd_unpoint()' API function should be able to return an error code because it may fail if you specify incorrect offset. This patch changes this MTD API function and amends all the drivers correspondingly. Also return '-EOPNOTSUPP' from 'mtd_unpoint()' when the '->unpoint()' method is undefined. We do not really need this currently, but this just makes sense to be consistent with 'mtd_point()'. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
