compute the number of iterations through the copy loop based
on file size; the miniroot image may be compressed. Instead,
ignore short reads in the NFS case, and handle them like EOF.
- Fix typo in a printf format.
cleaning calls will now be indirected throught the cpu_functions
that will have the correct function pointers for the CPU in use.
All register fixup code following aborts has been removed and
instead a call to the cpu_*abt_fixup() routine is called instead
to provide the correct fixed based on the CPU type and abort mode.
different ARM CPUS with different cache architectures for example to be
supported in a single kernel.
- All CPU/MMU/TLB specific functions are now held as function
pointers in a cpu_functions structure defined in machine/cpufunc.h
All coproc 15 accesses, TLB flushing, cache cleaning/flushing
and abort correction functions are now defined in this structure.
- cpufuncs is a global structure that is setup during initarm()
that holds all the function pointers for the booted CPU.
- A global variable 'cputype' now defines the probed cputype.
- All the existing functions for manipulating CPU specific features
have been replaced with macros defined in machine/cpufunc.h
that will call the appropriate function in the cpu_functions
structure.
- CPU functions are provided for selected CPU types (config options)
and the appropriate cpu_functions structure is chosen during
booting, based on the probed CPU type.
- All the required functions for existing CPU types (ARM6, ARM7 and
SA110) have been implemented.
space handles to describe the task file registers, aux register, 16 bit
data register and 32 bit data register.
The wdc softc structure has been moved to a separate file.
Added support for multiple attachments by separating the core of the
probe and attach functions from the mainbus probe and attach routines.
Added a new wdc flags 32_BIT so that the wd can determine 32 bit xfer
support from the wdc device.
that the common case can be handled with no hassles on all machines.
fix up the various internal variables which are also exported via sysctl
(and which therefore must be 'int's) to do the right thing via a special
read/write function.
