[U-Boot] [PATCH v4 00/25] MTD defconfigs/Kconfigs/Makefiles heavy cleanup
Hello, During my last project about SPI-NAND support in U-Boot, I discovered when modifying Makefiles a confusing organization where: * Sub-directories/files are compiled from the root Makefile * Commands are at the root of everything I sent a fist series a few weeks ago to move Makefile entries in their respective directories (which needed to be reworked). Since then, I have been working on clarifying all this for the MTD subsystem and here are the main points of such re-organization: * Rename CONFIG_MTD into CONFIG_DM_MTD to reserve CONFIG_MTD to what is called today CONFIG_MTD_DEVICE. * Fix build dependencies in defconfigs, like: "UBI and NAND depend on MTD". * Fix the Kconfig files to reflect these dependencies (as defconfigs have been updated, nothing should break). * Simplify the Makefiles: compiling the drivers/mtd/nand/raw/ sub-directory should just depend on MTD being compiled and the NAND core as well, there is absolutely no logic to make it depend on CMD_NAND. New green Travis CI build for the third version of this series: https://travis-ci.org/miquelraynal/u-boot/builds/463486099 There are three Sandbox tests that are failing, they have not been break by this series. The following Travis test has been done on the commit on which has been based the series and shows the same errors: https://travis-ci.org/miquelraynal/u-boot/builds/463593006 Thanks, Miquèl Note: as the number of Cc:'ed people reached 184 with get_maintainers.pl I decided to trim the list to: * People interested by the MTD subsystem. * A few maintainers: I had to tweak some defconfigs after more digging than with other boards (k2g, bcm11130, M54418TWR). Maintainers of these platforms are Cc:'ed. Changes since v3: = * As suggested by Vignesh, SPI_FLASH_MTD depends on MTD. Enforce this in Kconfig with a new patch. There is no defconfig to fix, all defconfigs with SPI_FLASH_MTD already use MTD. * s/coherent Makefile/appropriate Makefile/ in commit title of patch 1. * s/Kconfig/Makefile in commit message of "mtd: nand: remove dependency on commands in Kconfig" and "mtd: ubi: remove dependency on command in Kconfig". * Add Boris R-b tags. * Correct typos pointed by Boris. * Remove the if/endif in cmd/Kconfig about mtdparts, let the "depends on" that was already present. * Use an if/endif block to compile legacy-mtd-utils.c (to avoid failures when both 'sf' and 'nand' commands are compiled-in). * Merge all Makefile changes in one consistent commit as suggested by Boris. Changes since v2: = * Cleanup also applied to the SPL in an additional patch. * NOR dependency on MTD extracted from the patch adding MTD dependencies on commands only to do it in a separate change. * Typo s/copile/compile/ in "rename CONFIG_MTD_DEVICE..." commit log. * No more MTD depencency on SPI_FLASH, only kept on SPI_FLASH_MTD. * Same applies to the sf command. * Avoid compiling the NAND core while it is not needed (not speaking about the raw NAND core, really what is in drivers/mtd/nand:). * Last patch dropping CONFIG_MTD_PARTITIONS forgotten. We need them in order to reduce the final binary size. * Additional fixes in cmd/Kconfig. Changes since v1: = * Squashed both patches from the first series and included them in "mtd: simplify Makefiles". * Added all other patches. * Renamed CONFIG_NAND into CONFIG_MTD_RAW_NAND as suggested.
