if that ever changes, kmem_alloc_attr() would be the way to get it.

of the address space downwards, and then returning the lowest mapped
device address from initarm_lastaddr(). This adds over 500MB of kva
space compared to the old way of hardcoding the end address as 0xE0000000.
Also, pre-map most of the SoC's common memory-mapped devices using 1MB
section mappings so that all device access uses just a few TLB entries.
Graphics devices aren't mapped this way yet, but probably should be.
To provide this new functionality without pasting identical code into
multiple imxNN_machdep.c files, rework the imx machdep code so that
things common to the whole family of SoCs are in a new imx_machdep.c file.
The rewritten imxNN_machdep.c files contain just things specific to an
individual SoC.
previous KVA allocations (which the PMAP lazily invalidates) in TLB0 could
shadow device maps in TLB1. Add a big block comment about some of the
caveats with this approach.
BIO_new_mem_buf takes a void* buf, but internally it never modifies the
buf. It assigns the buffer to another pointer and then marks it as
read-only. So deconsting it should be safe here.
Also fix warning about 'buf' possibly being unused in parse_cert()

memory after the kernel.
- Provide pf_altq.h that has only stuff needed for ALTQ.
- Start pf.h, that would have all constant values and
eventually non-kernel structures.
- Build ALTQ w/o pfvar.h, include if_var.h, that before
came via pollution.
- Build tcpdump w/o pfvar.h.

interface. Make MII drivers forget about 'struct ifnet'.
Later plan is to provide an administrative downcall from ifnet
layer into drivers, to inform them about administrative status
change. If someone thinks that processing MII events for an
administratively down interface is a big problem, then drivers
would turn MII processing off.
The following MII drivers do evil things, like strcmp() on
driver name, so they still need knowledge of ifnet and thus
include if_var.h. They all need to be fixed:
sys/dev/mii/brgphy.c
sys/dev/mii/e1000phy.c
sys/dev/mii/ip1000phy.c
sys/dev/mii/jmphy.c
sys/dev/mii/nsphy.c

do not require that stdin be defined and equal to stdout: stdin is
nonstandard (for ePAPR) and console in an unexpected place is after all
better than no console.
- Remove explicit requirement that the SOC registers be found except as an
optimization (although the MPC85XX LAW drivers still require they be found
externally, which should change).
- Remove magic CCSRBAR_VA value.
- Allow bus_machdep.c's early-boot code to handle non 1:1 mappings and
systems not in real-mode or global 1:1 maps in early boot.
- Allow pmap_mapdev() on Book-E to reissue previous addresses if the
area is already mapped. Additionally have it check all mappings, not
just the CCSR area.
This allows the console on e500 systems to actually work on systems where
the boot loader was not kind enough to set up a 1:1 mapping before starting
the kernel.

When using DW UART with BUSY detection it is necessary to wait
until all serial transfers are finished before manipulating the
line control. LCR will not be affected when UART is busy.
In addition, if Divisor Latch Access Bit is being set in order to
modify UART divisors:
1. We will get BUSY interrupt if interrupts are enabled.
2. Because LCR will not be affected the THR and (even worse) IER
contents will be corrupted. This will lead to console hang.

If the pkg.conf is configured with SIGNATURE_TYPE: FINGERPRINTS,
and FINGERPRINTS: /etc/keys/pkg then a pkg.sig file is fetched along
with pkg.txz. The signature contains the signature provided by the
signing server, and the public key. The .sig is the exact output
from the signing server in the following format:
SIGNATURE
<openssl signed>
CERT
<rsa public key>
END
The signature is verified with the following logic:
- If the .sig file is missing, it fails.
- If the .sig doesn't validate, it fails.
- If the public key in the .sig is not in the known trusted fingerprints,
it fails.
- If the public key is in the revoked key list, it fails.
