The following patch merges the mmu and non-mmu versions of the m68k bitops.h files. Now there is a good deal of difference between the two files, but none of it is actually an mmu specific difference. It is all about the specific m68k/coldfire varient we are targeting. So it makes an awful lot of sense to merge these into a single bitops.h. There is a number of ways I can see to factor this code. The approach I have taken here is to keep the various versions of each macro/function type together. This means that there is some ifdefery with each to handle each CPU type. I have added some comments in a couple of appropriate places to try and make it clear what the differences we are dealing with are. Specifically the instruction and addressing mode differences we have to deal with. The merged form keeps the same underlying optimizations for each CPU type for all the general bit clear/set/change and find bit operations. It does switch to using the generic le operations though, instead of any local varients. Build tested on ColdFire, 68328, 68360 (which is cpu32) and 68020+. Run tested on ColdFire and ARAnyM.

If you say Y here, it will be possible to use a serial port as the
|
|
system console (the system console is the device which receives all
|
|
kernel messages and warnings and which allows logins in single user
|
|
mode). This could be useful if some terminal or printer is connected
|
|
to that serial port.
|
|
|
|
Even if you say Y here, the currently visible virtual console
|
|
(/dev/tty0) will still be used as the system console by default, but
|
|
you can alter that using a kernel command line option such as
|
|
"console=ttyS1". (Try "man bootparam" or see the documentation of
|
|
your boot loader (lilo or loadlin) about how to pass options to the
|
|
kernel at boot time.)
|
|
|
|
If you don't have a VGA card installed and you say Y here, the
|
|
kernel will automatically use the first serial line, /dev/ttyS0, as
|
|
system console.
|
|
|
|
If unsure, say N.
