but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).
With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
<arm32/machdep.h>
Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.
Remove the inclusion of this file.
Acorn32 now always builds load_memory_disc_from_floppy(). This should
not be a problem as all configs have md(4).

- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)
this gets called early in initarm(); this is as early as reasonable
for now; we might have to puch it back if the Slave ever depends
on the Master to do some setup work or something.
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
in mmu_init_table\gemini_start.S and devmap[]\gemini_machdep.c;
this allows some flexibility e.g. to map 'em all, which is useful
e.g. when using obio uart to debug lpc uart.
- add mmu_init_table entries for Gemini global regs, lpchc, and lpcio
these are needed to consinit() when console is lpc uart

- add mmu_init_table entries for Gemini global regs, lpchc, and lpcio

- now have 2 versions of consinit, one for obio uart,
the other for lpc uart; we use CONSADDR to determine
which gets compiled.
- remove a useless bus_space map/unmap from obio uart version of consinit
comcnattach() will do his own...
- use GEMINI_SLAVE, GEMINI_MASTER defines to distinguish between
primary and secondary CPUs, who owns what devices, etc.
- add short delay()s to allow console printf output to drain before reset
unless if ref_sc is not yet initialized, in which case tough.
- add devmap entriy for LPC
- add devmap entry for RAMDISK if MEMORY_DISK_DYNAMIC is defined
i.e. if the ramdisk is external to the kernel, in which case
we "know" where is lives by agreement with firmware.
- call md_root_setconf() if MEMORY_DISK_DYNAMIC is defined
progress markers; they are still useful for now.
in cpu_reboot() use Gemini Global Reset Control register to reboot system
geminiwdt_reboot() is no longer needed, removed.
