Greg Ungerer e87c09a899 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.
