memory: add ARM PL172 MultiPort Memory Controller driver This driver makes it possible to configure the static memory chip selects on the ARM PL172 MultiPort Memory Controller from a set of properties in DT. Configuration of dynamic memory is not supported and is left to the boot loader. The intended usage is to setup timing and configuration for static memory devices like NAND and NOR Flash before they are probed by a driver.

memory: pl172: add ARM PrimeCell PL175 MPMC support The change adds support of ARM PrimeCell PL175 MPMC, the controller is found on NXP LPC32xx SoC. PL175 MPMC is very similar to PL172 controller, so it is preferred to add its support into the existing driver. One of the differences between PL172 and PL175 is that the latter one supports up to 6 AHB ports, but still only 4 AHB ports can be assigned to a static memory device, also PL175 does not have write buffer enable control in static memory configuration register.

memory: pl172: add ARM PrimeCell PL176 MPMC support The change adds support of ARM PrimeCell PL176 MPMC. Static memory configuration of PL175 MPMC is very similar to one found on PL172 and PL175 controllers, so it is preferred to add its support into the existing driver. The difference is that PL176 supports up to 10 slave ports (but only 4 of them may be connected to static memory devices), AHB master bus width cab be 64-bit wide, also NAND devices can be interfaced. Similar to PL175 contoller, PL176 has no write buffer enable control in static memory configuration register, the rest of static memory configuration bits (with exception of NAND) is the same.

memory: pl172: fix modular build Building pl172 as a module fails with: > ERROR: "of_default_bus_match_table" [drivers/memory/pl172.ko] undefined! Because the symbol of_default_bus_match_table isn't exported by the OF core code so can't be referenced from modules. Fix this by removing the usage of of_default_bus_match_table for now. The side effect of this is that child nodes can't use "simple-bus" or "simple-mfd".
