06ea4a681d Don't assume that we are the PCI host. Actually check, and make sure that 
we set things up so that we can run either as a PCI host or as a PCI slave
(working within the PCI BARs that the system BIOS has configured for us).

87d5bba5b3 Replace the ad-hoc "section mapping table" for static device mappings 
with a more generic "devmap" structure that can also handle mappings
made with large and small pages.  Add new pmap routines to enter these
mappings during bootstrap (and "remember" the devmap), and routines to
look up the static mappings once the kernel is running.

0eff671820 Also pass a type argument to comcnattach() and com_kgdb_attach(). 
comspeed() (and thus cominit()) may need this information.

bbba90a2fb Don't expose KERNEL_TEXT_BASE outside of board-specific code. This gives 
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

Also in the ARM32_PMAP_NEW case, reclaim the USPACE-bytes of wasted space

long time.

d599df9587 Continue the " - . - 8" purge. Specifically: 
add	rd, pc, #foo - . - 8		->	adr	rd, foo
ldr	rd, [pc, #foo - . - 8]		->	ldr	rd, foo

Also, when saving the return address for a function pointer call, use
"mov lr, pc" just before the call unless the return address is somewhere
other than just after the call site.

Finally, a few obvious little micro-optimisations like using LDR directly
rather than ADR followed by LDR, and loading directly into PC rather than
bouncing via R0.

1a5a7fe7b7 Use indirect configuration for on-board devices (i.e. those things 
attached to "obio") on the IQ80310 and IQ80321.  It makes more sense
to do it this way for this type of system (the goal being to encapsulate
as much information about the board as possible into one file).

d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries, 
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

77a6866508 Enable caching on kernel and user page tables. This saves having 
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

79af00bddb Move the calls to uvm_page_physload() out of pmap_bootstrap() and 
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical.  Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

09eacc7061 Set COM_HW_NO_TXPRELOAD. The IQ80321's UART doesn't lose without 
this, but it works fine with it, and this serves to broaden the
