m68k: allow ColdFire 547x and 548x CPUs to be built with MMU enabled
m68k/Kconfig: Separate classic m68k and coldfire early
m68k: add ColdFire with MMU enabled support to the m68k mem init code
m68k: do not use m68k startup or interrupt code for ColdFire CPUs
m68k: add ColdFire FPU support for the V4e ColdFire CPUs
m68k: adjustments to stack frame for ColdFire with MMU enabled
m68k: use non-MMU linker script for ColdFire MMU builds
m68k: ColdFire with MMU enabled uses same clocking code as non-MMU
m68k: add code to setup a ColdFire 54xx platform when MMU enabled
m68k: use non-MMU entry.S code when compiling for ColdFire CPU
m68k: create ColdFire MMU pgalloc code
m68k: compile appropriate mm arch files for ColdFire MMU support
m68k: ColdFire V4e MMU paging init code and miss handler
m68k: use ColdFire MMU read/write bit flags when ioremapping
m68k: modify cache push and clear code for ColdFire with MMU enable
m68k: use tracehook_report_syscall_entry/exit for ColdFire MMU ptrace path
m68k: ColdFire V4e MMU context support code
m68k: MMU enabled ColdFire needs 8k ELF alignment
