indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
pass. Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:
icache_sync_all Synchronize I-cache
icache_sync_range Synchronize I-cache range
dcache_wbinv_all Write-back and Invalidate D-cache
dcache_wbinv_range Write-back and Invalidate D-cache range
dcache_inv_range Invalidate D-cache range
dcache_wb_range Write-back D-cache range
idcache_wbinv_all Write-back and Invalidate D-cache,
Invalidate I-cache
idcache_wbinv_range Write-back and Invalidate D-cache,
Invalidate I-cache range
Note: This does not yet include an overhaul of the actual asm files
that implement the primitives. Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.
* Use a common set of exception handlers for all arm32 platforms.
* New FIQ framework based on discussions with Ben Harris, shared
between arm26 and arm32.
parameters from first principles rather than using a static table for some
rates. This makes it work correctly on ARM7500, for which the table was
bogus (ARM7500 has a different refclk from VIDC20).
arch/arm/iomd/* .... the RC7500 isnt really an iomd/vidc machine but has
different video/audio chip and was kind of hardwired/hacked into the other
chip drivers.
The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.
Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.
This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.
RiscPC/A7000 have been tested and confirmed to build as should NC.
