mtd: Makefile: deep cleanup

2019-12-04T22:10:51Z

Move MTD-related lines out of the root Makefile. Put them in their respective directories. Enclose some of these new lines to skip them when building the SPL. MTD core files and some MTD device drivers are compiled in a mtd.o object and included in the final object only if MTD support is required (there are two different symbols for that, one for U-Boot and one for the SPL). Now that all defconfigs have been fixed, we can stop the logic where enabling a command selects the core files to compile. This logic is broken since selecting a symbol with a 'depends on' will not enforce this secondary dependency. Signed-off-by: Miquel Raynal

cmd: nand/sf: isolate legacy code

2019-12-04T22:10:51Z

The 'sf' command is not supposed to rely on the MTD stack, but both 'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite their location, these functions do not depend at all on the MTD stack. This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is selected, which is inconsistent with the current situation. Solve this by moving these three functions (which are only used by the above two commands) out of mtd_uboot.c and put them in a C file only compiled with cmd/sf.c and cmd/nand.c.

mtd: spi: SPI_FLASH_MTD depends on MTD

2019-12-04T22:10:51Z

It is already the case that all defconfigs with SPI_FLASH_MTD also declare using MTD, but let's make this consistent and enforce it in Kconfig. Most of the time SPI_FLASH_MTD is used in conjunction with UBI, which already depends on MTD. Suggested-by: Vignesh R Signed-off-by: Miquel Raynal

mtd: nand: add includes in NAND core to avoid warnings

2019-12-04T22:10:51Z

Because of the include's game, when some files are compiled for a SPI NAND device, no warning appears. But when it is for a raw NAND device, GCC complains. Fix these warning by including . Signed-off-by: Miquel Raynal Reviewed-by: Boris Brezillon

mtd: rename CONFIG_MTD_DEVICE -> CONFIG_MTD

2019-12-04T04:04:10Z

Like in Linux, just use CONFIG_MTD to compile the MTD stack. Signed-off-by: Miquel Raynal Reviewed-by: Boris Brezillon

mtd: rename CONFIG_MTD -> CONFIG_DM_MTD

2019-12-04T04:04:10Z

CONFIG_MTD must be reserved for the MTD core. Like any other subsystem, prefix the symbol by DM when it comes to DM support. Signed-off-by: Miquel Raynal Reviewed-by: Boris Brezillon [trini: Add Kconfig files] Signed-off-by: Tom Rini

mtd: rename CONFIG_NAND -> CONFIG_MTD_RAW_NAND

2019-12-04T04:04:10Z

Add more clarity by changing the Kconfig entry name. Signed-off-by: Miquel Raynal [trini: Re-run migration, update a few more cases] Signed-off-by: Tom Rini Reviewed-by: Boris Brezillon

mtd: mtdcore: Drop unused mtd_table

2019-12-03T13:43:24Z

The array 'mtd_table' is unused in the code. Remove this as gcc doesn't always discard unused global variables. Signed-off-by: Tom Rini

common: Move old EEPROM functions into a new header

2019-12-02T23:25:25Z

These functions do not use driver model but are still used. Move them to a new eeprom.h header file. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

common: Move command functions out of common.h

2019-12-02T23:25:02Z

Move these functions into the command.h header file which is a better fit. Signed-off-by: Simon Glass Reviewed-by: Tom Rini
