AcpiOsMapMemory()/AcpiOsUnmapMemory() (-> pmap_mapbios()/pmap_unmapbios())
for AcpiOsReadMemory() and AcpiOsWriteMemory(). Although they do not sound
too obvious, these functions are exclusively used to access memory mapped
IO in ACPICA.
According to ACPICA User Guide and Programmer Reference, the read data must
be zero extended to fill the 64-bit return value even if the bit width of
the location is less than 64.
- Return error when 64-bit access is requested as we do not support 64-bit
PCI register access (yet). XXX We may have to split it up into two 32-bit
accesses if it is really required.
According to ACPICA User Guide and Programmer Reference, the read data must
be zero extended to fill the 32-bit return value even if the bit width of
the port is less than 32.
- Remove 64-bit read/write from AcpiOsReadMemory() and AcpiOsWriteMemory().
These functions do not support 64-bit access (yet). Clean up style nits
and unnecessary bit masking while I am here.

r165114 added that code and that change ignored the same logic
committed in r135772. In addition, data FIFO protection should be
selectively enabled instead of applying to all PCIe devices.
While I'm here add BCM5785 to devices that do not require this
fix.
and remove a buffer overflow:
- Remove the array of per-type dispatch functions. Instead, pass each
structure to a single callback. The callback should check the type of
each table entry to take appropriate action. This matches the behavior
of other table walkers such as for the MP Table and MADT.
- Don't attempt to save an array of string pointers for each structure
entry. Instead, just skip the strings. If this code is reused to
provide a generic SMBIOS table walker in the future we could provide
a method that looks up a specific string N for a given structure record
instead of pre-populating an array of pointers. This fixes a buffer
overflow for structure entries with more than 20 strings.

The code in question verifies that all register write operations only change
bits that are defined (in the register definition file) for that effected
register. The bug effectively disabled this checking.
o Fix the check by testing the opcode against all supported read ("and" based)
operands.
o Add missing bit definitions to the aic7xxx and aic79xx register definition
files so that the warning (treated as a fatal error) does not spuriously
fire.

All of the necessary wrmsr calls are now preceded by a rdmsr

Do not grab lock while setting up interrupt, as it causes LOR with

While there, slightly improve attach errors handling.

The following systems are affected:
- MPC8555CDS
- MPC8572DS
This overhaul covers the following major changes:
- All integrated peripherals drivers for Freescale MPC85XX SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).
- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC,
QUICC, UART, CFI.
- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire
ocpbus(4) driver, which was based on hard-coded config data.
Note that world for these platforms has to be built WITH_FDT.

checksum offloading is enabled. The frame has a valid checksum
value so payload might be modified during TX checksum calculation.
Disable TX checksum offloading but give users chance to enable it
when they know their controller works without problems with TX
checksum offloading.
