Implement new ISA interface functions:
* isa_intr_alloc() - allocate an ISA IRQ
* isa_mem_alloc() - allocate ISA memory space
* isa_mem_free() - free ISA memory space
- Implement pioc device driver that handles the memory mapped serial,
parallel, floppy and IDE interfaces.
- Provide child attachments to the generic drivers for serial,
parallel and IDE.
- Removed mainbus specific code and moved the basic drivers from
arm32/mainbus to arm32/dev. Added code so that these drivers
will support multiple attachments from different ARM busses.
- Implement new time-of-day device. This device provides the
inittodr() and resettodr() functions and is designed to be a child
device of an RTC device. This allows one of multiple RTC's attached
to be used to provide the basic time of day functions.
- New home for lpt driver, (moved from arm32/mainbus) without the
mainbus specific attachments. (Revision history preserved).
- Hopefully this will be short lived with the new dev/ic/ lpt driver.
it was placed before `start', and start ended up misaligned. Add an alignment
directive for the start symbol. Of course ld(1) should not core-dump relocating
misaligned symbols, but this will be fixed shortly.
The isa attachment code is in isa/lpt_isa.c now, which attaches to the
already created ic/lpt* files.
You don't need to change your config files, but you need to re-"config" if
using lpt at isa.
XXX The "lpt" device definition should be in sys/conf/files instead, but to
my knowledge, there are some ports which have private copies of lpt, and would
choke on that. No need to make people unhappy 7 days before release branching.
- the console code from arm32/dev has been moved here as it is VIDC
specific.
- A few minoir code cleanups to help it fit with the restructures VIDC
sources
Removed all the old code for allocation / management of level 1 page
tables.
Implemented new static / dynamic L1 page table allocation / management
using vm_page_alloc_memory().
Fixed bug in pmap_page_index() when specifing addresses between memory
banks.
Serious cleanup up of the comments
- Major overhaul.
- Removed all the RiscPC and RC7500 specific code and moved that into
separate files for the two machine architectures.
- This routine now provides support for the machine specific machdep
code and provides cpu_startup().
The following patch employs a smarter adaptive polling
scheme. It also improves the comments, in particular giving
due credit to Phil Budne for his efforts in nunderstanding
the device. It also relaxes the pattern for auto config so
more devices match.
- New versions of the drivers for the devices that really are IOMD
specific. The old arm32/mainbus drivers have either been rewritten
and are now child devices of the IOMD or they have been restructured
and split into generic drivers will IOMD specific attachments.
- These files are not generic or even really mainbus specific.
They are IOMD specific device.
- These devices have been re-written as child devices of the IOMD
device and the new versions will take up residence in the arm32/iomd
directory with the other IOMD specific code.
- IOMD specific clock support. This used to the the generic ARM clock
support but is now specific to the IOMD device.
- Updated to support new IOMD device etc.
