m68k: print memory layout info in boot log
Output a table of the kernel memory regions at boot time.
This is taken directly from the ARM architecture code that does this.
The table looks like this:
Virtual kernel memory layout:
vector : 0x00000000 - 0x00000400 ( 0 KiB)
kmap : 0xd0000000 - 0xe0000000 ( 256 MiB)
vmalloc : 0xc0000000 - 0xcfffffff ( 255 MiB)
lowmem : 0x00000000 - 0x02000000 ( 32 MiB)
.init : 0x00128000 - 0x00134000 ( 48 KiB)
.text : 0x00020000 - 0x00118d54 ( 996 KiB)
.data : 0x00118d60 - 0x00126000 ( 53 KiB)
.bss : 0x00134000 - 0x001413e0 ( 53 KiB)
This has been very useful while debugging the ColdFire virtual memory
support code. But in general I think it is nice to know extacly where
the kernel has layed everything out on boot.
