2016-04-25mtd: maps: make uclinux.c driver more explicitly non-modularPaul Gortmaker1-23/+4
The Kconfig for this support is currently declared with: config MTD_UCLINUX bool "Generic uClinux RAM/ROM filesystem support" ...meaning that it currently is not being built as a module by anyone. Lets remove as much of the modular evidence that we can, so that when reading the driver there is less doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We also replace module.h with moduleparam.h since the file does use a module_param, and leaving it as such is currently the easiest way to remain compatible with existing boot arg use cases. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

2016-04-26physmap_of: ensure versatile code is reachableArnd Bergmann2-1/+5
With the newly added physmap_of_versatile code, we get a build error when physmap_of is in a module, because of_flash_probe_versatile is not exported: ERROR: "of_flash_probe_versatile" [drivers/mtd/maps/physmap_of.ko] undefined! This adds the export, and changes the Makefile so that the code is also put into a loadable module rather than built-in when physmap_of itself is a module.

2016-04-19mtd: create an mtd_ooblayout_ops struct to ease ECC layout definitionBoris Brezillon4-48/+146
ECC layout definitions are currently exposed using the nand_ecclayout struct which embeds oobfree and eccpos arrays with predefined size. This approach was acceptable when NAND chips were providing relatively small OOB regions, but MLC and TLC now provide OOB regions of several hundreds of bytes, which implies a non negligible overhead for everybody even those who only need to support legacy NANDs. Create an mtd_ooblayout_ops interface providing the same functionality (expose the ECC and oobfree layout) without the need for this huge structure. The mtd->ecclayout is now deprecated and should be replaced by the equivalent mtd_ooblayout_ops. In the meantime we provide a wrapper around the ->ecclayout field to ease migration to this new model.
