While use of fsl_ifc driver with NAND flash is fine, as the fsl_ifc_nand
driver selects FSL_IFC automatically, we need the CONFIG_FSL_IFC option to

memory: atmel-sdramc: remove the driver

Driver does only clock request + enable for DDR clocks. DDR clocks are
enabled by bootloader and need to stay that way in Linux. To avoid having
these clocks disabled by clock subsystem in case there are no Linux
consumers for them the clocks were marked as critical in clock drivers
(in commit 68b3b6f1773d ("clk: at91: mark ddr clocks as critical")).
With this, there is no need to have a separate driver that only does
clock request + enable.

Allow OMAP_GPMC to be built as a module.

When building this driver as a module, the symbol
'of_default_bus_match_table' will not be found as it is not being
exported.

The of_match_node() call is redundant anyways as
of_platform_default_populate() already takes care of matching with
'of_default_bus_match_table'. So get rid of that call. This will also
resolve the module build failure.

Move compatible match table to the end where it is usually expected.

memory: omap-gpmc: Make OMAP_GPMC config visible and selectable

So far for armv7 TI platforms, GPMC was being selected by

For K3 platforms, GPMC is no longer required for basic boot and cannot
be always enabled by default by mach- Kconfig.

We need a way for user (or board defconfig) to enable it if required so

The purpose of memory clearing block is to zero out all private memory
when FPGA is to be reprogrammed. This gives users a reliable method to
prevent potential data leakage.
