Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

config OMAP_MUX
	bool "OMAP multiplexing support"
	default y
	help
	  Pin multiplexing support for OMAP boards. If your bootloader
	  sets the multiplexing correctly, say N. Otherwise, or if unsure,
	  say Y.

config OMAP_MUX_DEBUG
	bool "Multiplexing debug output"
	depends on OMAP_MUX
	help
	  Makes the multiplexing functions print out a lot of debug info.
	  This is useful if you want to find out the correct values of the
	  multiplexing registers.

config OMAP_MUX_WARNINGS
	bool "Warn about pins the bootloader didn't set up"
	depends on OMAP_MUX
	default y
	help
	  Choose Y here to warn whenever driver initialization logic needs
	  to change the pin multiplexing setup.	 When there are no warnings
	  printed, it's safe to deselect OMAP_MUX for your product.

config OMAP_32K_TIMER
	bool "Use 32KHz timer"
	depends on ARCH_OMAP16XX
	default ARCH_OMAP16XX
	help
	  Select this option if you want to enable the OMAP 32KHz timer.
