fdeb609887 Place a remark ... the old vidcconsole code can't handle the comconsole 
not yet for it is called early in the init_arm() ... this needs to be
patched one day so it can be called very early; but is this possible ?

242cca702b Part one of the COMCONSOLE repair ... it works now but the video console 
is effectively dead instead... this needs work. Also the boottime switching
to the vidcconsole would be good.

4c8caed00d Apply a bandage to delay() so that it takes a more suitable time on 
StrongARM Risc PCs.  It really should be replaced entirely, but I've got more
important bugs to fix.

4b7f5e2feb Add hardware scrolling to the RiscPC wscons implementation. 
There are still some minor oddities esp. at startup but after that it
functions OK.

The scrolling speed is increased *dramatically* and allmost even faster
compared to the old vidcconsole code; *NOT* tested yet on non-VRAM machines.

20ba07f2fe - add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx((*))) yyy", 
and use appropriately

- create more helper macros:
   . cdev__xyz_init(c,n), such as cdev__ocri_init() for
     /* open, close, read, ioctl */, etc.
   . cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
     method `R' and the comments now read /* xxx (read) yyy */ instead
   . cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
     as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
  always DTRT WRT returning a valid result.  (a few devices previously
  incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
  == 0, because it doesn't matter if dev_type_stop isn't implemented in that
  case, and it allows the use of the cdev__xyz_init macros. certain ports
  (sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
  drivers, whereas everything else uses enodev

- ensure that the comments are accurate WRT the behaviour of a given entry

903b8688da The interface to `setdisplay' was implemented wrong. The utility stated the number

2714607c72 Add podulebus_shift_tag, which generates a bus_space_tag_t with a specified 
address shift (stride).  This is necessary because many podules have standard

bus_space_*_multi_*().

df2b9ae2bd Initial commit of wscons for the RiscPC/A7000 arm32 family. There is still lots 
to do notably the mouse, some issues about 4 bpp modes and most of all Xwscons !

This code will still allow usage of the old vidcconsole complete with X etc.
Note that the wscons code can now only be booted with the new bootloader but
kernels compiled with vidcconsole can still be booted the old way.

Initially I gave it the type `int *iomd_base' but some macro's defined in

registers offsets were multiplied by four and that can only mean trouble !

7535275b7c Fixed the `slow printing' bug that occured with debugged kernels on RiscPC's. 
When the IOMD isnt mapped and all is mapped 1:1 a read gives garbage and thus
the obscure feature that slows down printing (or halts it!) when the mouse
button is pressed during output to the vidcconsole gets allways activated.

Included a simple flag that signals if the IOMD is mapped; the delay routine
won't check the mouse if this flag is still clear.

7665787d5e Fix to solve PR arm32/9208 "RiscPC reboot hangs" 
Due to the StrongARM support code in the cpu_reset() MC-function,
an instruction was executed to drain the write back buffer on StrongARM
processors (might even be armv4+).

Since ARM{6,7} don't recognize this instruction they will either except
for an illegal instruction on this or have undefined behaviour resulting
in an endless illegal instruction/data abort/reset behaviour.

The fix contains a flag that signals if the WB flush should be executed
or not for the detected processor.
