violation should be activated unless the system is cold-booted
after updating EEPROM.
The PCI protocol violation happens only when established link is
10Mbps so the workaround should be updated whenever link state
change is detected. Previously the workaround was activated only
when user checks current media status with ifconfig(8).
whether the checksum of EEPROM is valid or not. Because driver
heavily relies on EEPROM information when it selectively enables
features/workarounds, it would be helpful to know whether driver
sees valid EEPROM.
While I'm here remove all other EEPROM accesses since the entire
EEPROM is loaded at device attach time.

for 82550C. For 82550 controllers this change restores CPUSaver
microcode loading. Due to silicon bug on 82550 and 82550C with
server extension, these controllers seem to require CPUSaver
microcode to receive fragmented UDP datagrams. However the
microcode shouldn't be used on client featured 82550C as it locks
up the controller. In addition, client featured 82550C does not
have the silicon bug. Also clear temporary memory used for
microcode loading since the same memory area is used for other
commands.
While I'm here use 82550C in probe message instead of generic
82550.

The 'make depend' rules have to use custom -I paths for the special compat
includes for the opensolaris/zfs headers.
This option will pull in the couple of files that are shared with dtrace,
but they appear to correctly use the MODULE_VERSION/MODULE_DEPEND rules
so loader should do the right thing, as should kldload.

The on-chip SD slots do not have PCI BARs corresponding to them, so
this has to be handled in the custom SoC memory allocation.
Provide memory resource for rids corresponding to BAR 0 and 1 in
the custom allocation code.
The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
he default bus space cannot be used for these.
Subclass pci and override attach and resource allocation methods to
take care of this.
Remove earlier code which did this partially.
Temporarily revert an upstream commit. This change caused regressions for
too many laptop users. Especially, automatic repair for broken _BIF caused
strange reference counting issues and kernal panics. This reverts:

SCTP will only do IPv4 UDP checksum calculation as defined by the host
policy. When tunneling SCTP always calculates the inner checksum already
so not doing the outer UDP can save cycles.

The flash commands and responses are little-endian and have to be
byte swapped on big-endian systems. However the raw read of data
need not be swapped.
Make the cfi_read and cfi_write do the swapping, and provide a
cfi_read_raw which does not byte swap for reading data from
flash.
loaded and unloaded, also have sdt.ko register callbacks with kern_sdt.c
that will be called when a newly loaded KLD module adds more probes or
a module with probes is unloaded.
This fixes two issues: first, if a module with SDT probes was loaded after
sdt.ko was loaded, those new probes would not be available in DTrace.
Second, if a module with SDT probes was unloaded while sdt.ko was loaded,
the kernel would panic the next time DTrace had cause to try and do
anything with the no-longer-existent probes.
This makes it possible to create SDT probes in KLD modules, although there
are still two caveats: first, any SDT probes in a KLD module must be part
of a DTrace provider that is defined in that module. At present DTrace
only destroys probes when the provider is destroyed, so you can still
panic the system if a KLD module creates new probes in a provider from a
different module(including the kernel) and then unload the the first module.
Second, the system will panic if you unload a module containing SDT probes
while there is an active D script that has enabled those probes.

Move XLP PCI UART device to sys/mips/nlm/dev/ directory. Other
drivers for the XLP SoC devices will be added here as well.
Update uart_cpu_xlp.c and uart_pci_xlp.c use macros for uart port,
speed and IO frequency.
Features:
- network driver for the four 10G interfaces and two management ports
on XLP 8xx.
- Support 4xx and 3xx variants of the processor.
- Source code and firmware building for the 16 mips32r2 micro-code engines
in the Network Accelerator.
- Basic initialization code for Packet ordering Engine.

On XLP evaluation platform, the board information is stored
in an I2C eeprom and the network block configuration is available
from a CPLD connected to the GBU (NOR flash bus). Add support
for both of these.
Support for the Security and RSA blocks on XLP SoC. Even though
the XLP supports many more algorithms, only the ones supported
in OCF have been added.
