2018-12-07mtd: rawnand: ams-delta: Allow this driver to be compiled when COMPILE_TEST=yBoris Brezillon1-1/+1
Drop the asm and mach headers inclusion and allow this driver to be compiled when COMPILE_TEST=y in order to increase compile-test coverage.

2018-10-03mtd: rawnand: Remove docg4Boris Brezillon1-20/+0
The diskonchip G4 driver does not fit very well in the raw/parallel NAND framework simply because such chips have an internal controller translating DoC-specific commands into NAND ones. Keeping such a driver in the raw NAND framework is a real burden for NAND maintainers. Not to mention that some parts of this driver are a bit worrisome: - writes are done by subpages, even though we're interfacing with an MLC chip which are known to not support subpage writes very well (it might be that the FTL handles the complexity for us though) - some part of the code are simply ignoring return codes of function that can fail in a few occasions - there's a hack to support OOB writes when no data is provided. This operation is not supported by the chip and should have been rejected, and nandwrite and other userspace tools should have been patched to deal with such devices - the driver is apparently broken when ignore_badblocks module param is not set to 1 and nobody noticed that (don't know since when this is the case, but it's not a recent change) http://lists.infradead.org/pipermail/linux-mtd/2018-July/082472.html Add to that the fact that we already have a docg3 driver in drivers/mtd/devices/docg3.c and, looking at the code (and regs), it seems docg3 and docg4 have a lot in common (even the author of this driver seemed to have realized that interfacing with the raw NAND framework might have been a bad idea http://lists.infradead.org/pipermail/linux-mtd/2012-January/039517.html). For all these reasons, I'm proposing to remove this driver. If anyone ever wants to add support for this chip back, I'd suggest extending the docg3 driver instead of adding a completely new driver.

2018-07-19mtd: rawnand: MTD_NAND_BCM47XXNFLASH needs CONFIG_BCMAArnd Bergmann1-0/+1
We already have a dependency on BCMA_NFLASH, which in turn depends on BCMA, but since BCMA is a tristate option and BCMA_NFLASH is bool, we can run into an invalid configuration with MTD_NAND_BCM47XXNFLASH=y and BCMA=m: drivers/mtd/nand/raw/bcm47xxnflash/ops_bcm4706.o: In function `bcm47xxnflash_ops_bcm4706_init': ops_bcm4706.c:(.text+0x790): undefined reference to `bcma_chipco_pll_read' Adding the dependency here forces MTD_NAND_BCM47XXNFLASH to only be configured =m here so it can link against the BCMA driver.

2018-04-21mtd: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven1-6/+2
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.
