3f817dd216 Stop using the global fdtbus_bs_tag and instead use the tag from the softc

b1c2e02c10 This code no longer references fdtbus_bs_tag, no need for a special extern

99c4102214 Now that we have OF_decode_addr(), with proper MD implementations, to obtain
the bus space tag and handle for a uart console, use the values returned by
that routine to set the global uart_bus_space_mem, instead of assuming that
there will be a global variable named fdtbus_bs_tag to set it from.

Also, use OF_getencprop() instead calling fdt32_to_cpu() separately.

0a01ff4d7d Fix and clean up usage of DMA and TSO segments:
- At Intel it is believed that most of their products support "only"
  40 DMA segments so lower {EM,IGB}_MAX_SCATTER accordingly. Actually,
  40 is more than plenty to handle full size TSO packets so it doesn't
  make sense to further distinguish between MAC variants that really
  can do 64 DMA segments. Moreover, capping at 40 DMA segments limits
  the stack usage of {em,igb}_xmit() that - given the rare use of more
  than these - previously hardly was justifiable, while still being
  sufficient to avoid the problems seen with em(4) and EM_MAX_SCATTER
  set to 32.
- In igb(4), pass the actually supported TSO parameters up the stack.
  Previously, the defaults set in if_attach_internal() were applied,
  i. e. a maximum of 35 TSO segments, which made supporting more than
  these in the driver pointless. However, this might explain why no
  problems were seen with IGB_MAX_SCATTER at 64.
- In em(4), take the 5 m_pullup(9) invocations performed by em_xmit()
  in the TSO case into account when reporting TSO parameters upwards.
  In the worst case, each of these calls will add another mbuf and,
  thus, the requirement for an additional DMA segment. So for best
  performance, it doesn't make sense to advertize a maximum of TSO
  segments that typically will require defragmentation in em_xmit().
  Again, this leaves enough room to handle full size TSO packets.
- Drop TSO macros from if_lem.h given that corresponding MACS don't
  support TSO in the first place.

e28fbecafb Make imx6 systems work again after recent import of new dts files.
Linux-driven changes to the way the chip's two interrupt controllers are
defined (we only support one of them) led to no interrupt processing, so
the system would hang after device instantiation.  This workaround just
rewrites the FDT data on the fly to get interrupt handling back under the
control of the main GIC device.

If/when we ever support deep sleep modes that involve powering down the
main GIC, we'll have to undo this change, write a driver for the GPC-PIC,
and somehow manage the handoff of responsibilities between the two drivers
as the chip transitions in/out of deep sleep mode.

72e8ce06c0 Fix a problem in ld, causing it to sometimes print messages similar to
"invalid string offset 65521 >= 27261 for section `.strtab'". for object
files produced by recent versions of clang.

In BFD's elf_create_symbuf() function, the size of the symbol buffer
('ssymbuf') is not calculated correctly, and the initial value for the
'ssym' variable is off by one, since 'ssymbuf' has shndx_count + 1
members.

0d2550a169 If the user has set a u-boot env var named rootpath, automatically
import it into the loader(8) env as dhcp.root-path, so that it overrides
any dhcp/bootp server-provided path.

Now if you have a dhcp server available you can easily net-boot a u-boot
system even if you don't control the dhcp server config, by setting just
two variables in the u-boot env:

  loaderdev=net
  rootpath=<nfsserverip>:<pathname>

Previously you had to either accept all the dhcp parameters from the
server without the ability to locally provide the rootpath, or you had
to forego dhcp and set more vars (ipaddr, netmask, serverip, rootpath).

e1ba387e11 Unconditionally set e_ident[OSABI]=ELFOSABI_FREEBSD in arm binary headers.
When the armv6 support was imported from a project branch, this complex
conditional logic and related #define'd values came along, but it's really
not clear what the intent of it all was.  The effect, however, was that
OSABI was always set to zero, which is "UNIX System V ABI".  Having the wrong
value there causes pkg(8) to avoid looking inside arm elf binaries to
determine shared-lib required/provides info for packaging.

1e1bbb79fd Fix "invalid type '(null)'" usage messages in zfs(8) and zpool(8).
Currently, zfs(8) and zpool(8) print "invalid type '(null)'" or similar
messages, if you pass in invalid types, sources or column names for "zfs
get", "zfs list" and "zpool get".  This is because the commands use
getsubopt(3), and in case of failure, they print 'value', which is NULL
when sub options don't match.

They should print 'suboptarg' instead, which is the documented way to
get at the non-matching sub option value.

is executed under some non-sleepable mutexes.

lock-less method to get UID, use the method from the dmar hpet

Import portions of the PowerPC OF PCI implementation into

ofw_pci.h from sys/powerpc/ofw no longer exist. All required declarations
are moved to sys/dev/ofw/ofw_pci.h.

This creates a new ofw_pci_write_ivar() function and modifies
ofw_pci_nranges(), ofw_pci_read_ivar(), ofw_pci_route_interrupt()
methods.
Most functions contain existing ppc implementations in the majority
unchanged. Now there is no need to have multiple identical copies
