Raw NAND controllers drivers changes: - Qcom: structuring cleanup. - Denali: use core helper to find the best ECC configuration. - Possible build of almost all drivers by adding a dependency on COMPILE_TEST for almost all of them in Kconfig, implies various fixes, Kconfig cleanup, GPIO headers inclusion cleanup, and even changes in sparc64 and ia64 architectures. - Clean the ->probe() functions error path of a lot of drivers. - Migrate all drivers to use nand_scan() instead of nand_scan_ident()/nand_scan_tail() pair. - Use mtd_device_register() where applicable to simplify the code. - Marvell: * Handle on-die ECC. * Better clocks handling. * Remove bogus comment. * Add suspend and resume support. - Tegra: add NAND controller driver. - Atmel: * Add module param to avoid using dma. * Drop Wenyou Yang from MAINTAINERS. - Denali: optimize timings handling. - FSMC: Stop using chip->read_buf(). - FSL: * Switch to SPDX license tag identifiers. * Fix qualifiers in MXC init functions. Raw NAND chip drivers changes: - Micron: * Add fixup for ONFI revision. * Update ecc_stats.corrected. * Make ECC activation stateful. * Avoid enabling/disabling ECC when it can't be disabled. * Get the actual number of bitflips. * Allow forced on-die ECC. * Support 8/512 on-die ECC. * Fix on-die ECC detection logic. - Hynix: * Fix decoding the OOB size on H27UCG8T2BTR. * Use ->exec_op() in hynix_nand_reg_write_op().

| | | | | | | | | | | | | | | | | | | | Now that it is possible to do dynamic allocations during the identification phase, convert the onfi_params structure (which is only needed with ONFI compliant chips) into a pointer that will be allocated only if needed.

| | | | | | | | | | | | | | | | | | | | Thanks to the migration of all drivers to use nand_scan() and the related nand_controller_ops, we can now allocate data during the detection phase.

| * mtd: rawnand: do not export nand_scan_[ident|tail]() anymoreMiquel Raynal2018-07-312-19/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both nand_scan_ident() and nand_scan_tail() helpers used to be called directly from controller drivers that needed to tweak some ECC-related parameters before nand_scan_tail(). This separation prevented dynamic allocations during the phase of NAND identification, which was inconvenient. All controller drivers have been moved to use nand_scan(), in conjunction with the chip->ecc.[attach|detach]_chip() hooks that actually do the required tweaking sequence between both ident/tail calls, allowing programmers to use dynamic allocation as they need all across the scanning sequence. Declare nand_scan_[ident|tail]() statically now. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Boris Brezillon <boris.brezillon@bootlin.com>

| | | | | | | | | | | | | | | | | | | | | | A comment in the probe declares that values are assigned to ecc.size and ecc.bytes, but these values will be overwritten. This is not entirely right as they are overwritten only if mtd->writesize >= 512. Let's clarify this by moving these assignations to txx9ndfmc_nand_scan().

| | | | | | | | | | | | | | | | | | | | | | | | Some driver (eg. docg4) will need to handle themselves the identification phase. As part of the migration to use nand_scan() everywhere (which will unconditionnaly call nand_scan_ident()), we add a condition at the start of nand_scan_with_ids() to jump over nand_scan_ident() if the maxchips parameters is zero, meaning that the driver does not want the core to handle this phase.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | asm-generic/io.h provides a generic implementation of all I/O accessors, which the architectures can override. Since ia64 does not provide readsl/writesl etc, any driver using those fails to build, and including asm-generic/io.h will provide the missing interfaces, as well as any other future interfaces that get added there. We need to #define a couple of symbols to themselves in the ia64 to ensure that we use the ia64 specific version of those rather than the generic one. There should be no other effect than adding {read,write}s{b,w,l}() as well as {in,out}s{b,w,l}_p(), which were also not provided by ia64 but are provided by the generic header for historic reasons.

Implement these hooks so that we can convert the driver to just use nand_scan() instead of the nand_scan_ident() + nand_scan_tail() pair.

| * mtd: rawnand: add hooks that may be called during nand_scan()Miquel Raynal2018-07-312-2/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to remove the limitation that forbids dynamic allocation in nand_scan_ident(), we must create a path that will be the same for all controller drivers. The idea is to use nand_scan() instead of the widely used nand_scan_ident()/nand_scan_tail() couple. In order to achieve this, controller drivers will need to adjust some parameters between these two functions depending on the NAND chip wired on them. This takes the form of two new hooks (->{attach,detach}_chip()) that are placed in a new nand_controller_ops structure, which is then attached to the nand_controller object at driver initialization time. ->attach_chip() is called between nand_scan_ident() and nand_scan_tail(), and ->detach_chip() is called in the error path of nand_scan() and in nand_cleanup(). Note that some NAND controller drivers don't have a dedicated nand_controller object and instead rely on the default/dummy one embedded in nand_chip. If you're in this case and still want to initialize the controller ops, you'll have to manipulate chip->dummy_controller directly. Last but not least, it's worth mentioning that we plan to move some of the controller related hooks placed in nand_chip into nand_controller_ops to make the separation between NAND chip and NAND controller methods clearer.
