* mtd: rawnand: Get rid of chip->ecc_{strength,step}_dsBoris Brezillon2019-04-0815-85/+81
| | | | | | | | | | | | nand_device embeds a nand_ecc_req object which contains the minimum strength and step-size required by the NAND device. Drop the chip->ecc_{strength,step}_ds fields and use chip->base.eccreq.{strength,step_size} instead.

| | | | | | | | | | | | | nanddev_mtd_max_bad_blocks() is implemented by the generic NAND layer and is already doing what we need. Reuse this function instead of having our own implementation.

* mtd: rawnand: Prepare things to reuse the generic NAND layerBoris Brezillon2019-04-081-4/+6
| | | | | | | | | | | | | | | | The generic NAND layer provides abstraction of NAND devices no matter the bus that is used to communicate with the chip. Basing the raw NAND core on this generic layer should avoid duplication of common operations, like iterating over all pages/blocks for MTD IO/erase operations. In order to re-use this layer, we must first inherit from nand_device and then initialize the nand_device struct appropriately. This patch is taking care of the former.

| * kconfig: remove stale lxdialog/.gitignoreMasahiro Yamada2019-03-171-4/+0
| | | | | | | | | | | | | | | | | | When this .gitignore was added, lxdialog was an independent hostprogs-y. Now that all objects in lxdialog/ are directly linked to mconf, the lxdialog is no longer generated. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
| * kbuild: force all architectures except um to include mandatory-yMasahiro Yamada2019-03-1729-47/+18
| | | | | | | | | | | | | | | | | | | | | | | | Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

| * kbuild: warn redundant generic-yMasahiro Yamada2019-03-1712-13/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic-y is redundant under the following condition: - arch has its own implementation - the same header is added to generated-y - the same header is added to mandatory-y If a redundant generic-y is found, the warning like follows is displayed: scripts/Makefile.asm-generic:20: redundant generic-y found in arch/arm/include/asm/Kbuild: timex.h I fixed up arch Kbuild files found by this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit caf6fe91ddf62a96401e21e9b7a07227440f4185. The commit was fine but is no longer needed as of commit 3a2429e1faf4 ("kbuild: change if_changed_rule for multi-line recipe"). Let's go back to using ";" to be consistent.

| * kbuild: Make NOSTDINC_FLAGS a simply expanded variableDouglas Anderson2019-03-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a simple no-op (nothing changed) build I saw 39 invocations of the C compiler with the argument "-print-file-name=include". We don't need to call the C compiler 39 times for this--one time will suffice. Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid this since there doesn't appear to be any reason it should be recursively expanded. On my build this shaved ~400 ms off my "no-op" build. Note that the recursive expansion seems to date back to the (really old) commit e8f5bdb02ce0 ("[PATCH] Makefile include path ordering"). It's a little unclear to me if the point of that patch was to switch the variable to be recursively expanded (which it did) or to avoid directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because someone else (out of tree?) was setting it. I presume later since if the only goal was to switch to recursive expansion the patch would have just removed the ":".
