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.

Two helpers have been added to the core to do all kind of controller side configuration/initialization between the detection phase and the final NAND scan. 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.

No need for an atmel_nand_register() function, let's move the code in it directly where the function was called: in atmel_nand_controller_add_nand(). To make things consistent, also rename atmel_nand_unregister() into atmel_nand_controller_remove_nand().

Some drivers need these for compile-testing. On most architectures they come from asm-generic/io.h, but not on sparc64, which has its own definitions. Since we already have ioread*_rep()/iowrite*_rep() that have the same behavior on sparc64 (i.e. all PCI I/O space is memory mapped), we can rename the existing helpers and add macros to define them to the same implementation.

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.

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.

In the raw NAND core, a NAND chip is described by a nand_chip structure, while a NAND controller is described with a nand_hw_control structure which is not very meaningful. Rename this structure nand_controller. As the structure gets renamed, it is logical to also rename the core function initializing it from nand_hw_control_init() to nand_controller_init(). Lastly, the 'hwcontrol' entry of the nand_chip structure is not meaningful neither while it has the role of fallback when no controller structure is provided by the driver (the controller driver is dumb and can only control a single chip). Thus, it is renamed dummy_controller. Signed-off-by: NMiquel Raynal <miquel.raynal@bootlin.com> Acked-by: NBoris Brezillon <boris.brezillon@bootlin.com>
