 1.8  21-Oct-2009  rmind Drop 3rd and 4th clauses from Ichiro FUKUHARA's license.
Reviewed and approved by ichiro@ (copyright holder).
 1.7  06-Mar-2003  igy branches: 1.7.110;
insert macro to protect itself against multiple includion.
 1.6  22-Feb-2003  igy correct physical/virtual address handling

- to identify device instance, using hardware address.
- when console accesses device, using statically mapped address.
- when tty accesses device, using handler given by bus_space_map().

no need device ixpcom in evbarm/conf/files.evbarm move it to
arm/ixp12x0/files.ixp12x0

ixp12x0_com.c:
some fix around address handling
1. Do not call bus_space_map() in ixpcominit(). Calling bus_space_map()
is not safe here, because bus_space_map() calls uvm_km_valloc() but
uvm is not yet initialized.
2. Use dv_unit to determine console instead comparering iobase.
Now you can attach ixpcom0 with physical address like this:
ixpcom* at ixpsip? addr 0x90000000 size 0x4000
Statically mapped address (0xf0000000) is still usable.

ixp12x0_clk:
1. access PLL_CFG register via bus_space
2. Make the delay() working correctly. (bug fix)
3. Start the timer device without interrupt on attach time.
Now delay() called before cpu_initclocks() works fine.

ixp12x0_pci:
1.Mapping PCI type0/1 configuration space to the upper address.
2."PCI I/O Cycle Access" mapping to same virtual address(VA==PA)
but size of this mapping increase to 1MByte because fails
cause couldnt set L2 table.
3.use bus_space address handling in ixp12x0_pci.c.
 1.4  03-Dec-2002  ichiro initialize ixpcomconsaddr
use splserial()
fix IXPCOM registers
 1.3  02-Dec-2002  ichiro use bus_space map
 1.2  20-Jul-2002  ichiro branches: 1.2.2; 1.2.4; 1.2.6;
attach/match separated from ixp12x0_com
