address to populate slot member.
@li pci: Add function devPCIFindSpec() to search by text string.
    Understands PCI bus address, slot number, and/or instance number
@li Add devPCIShowMatch() variant of devPCIShow() using devPCIFindSpec().

@subsection ver27 2.7 (Jan. 2016)

@li configure: optionally include \$(TOP)/configure/RELEASE.local and \$(TOP)/../RELEASE.local.
    \$(EPICS_BASE) is no longer defined by default in configure/RELEASE and must
    be explicitly set in one of the possible RELEASE* files.
@li Fix compile failure on vxWorks (Eric Bjorklund)
@li Add missing extern "C" in epicsMMIO.h for vxWorks (Eric Bjorklund)
@li In epicsMMIODef.h replace 'inline' with 'static inline' for C compatibility.
@li RTEMS: handle BSPs with offset PCI addresses
@li pci/linux: devPCIDebug>1 enables more debug output when searching/matching PCI devices.
@li pci/linux: fix error preventing use of uio devices other than uio0.
@li vme: add vmewrite(), vmeirqattach(), and vmeirq() iocsh commands
    for debugging/development with VME devices.

@subsection ver26 2.6 (May 2015)

@li VCS repository moved to github.com
@li Increment API version to 1.2 (was 1.0)
@li epicsMMIO.h included in EPICS Base 3.15.1, not installed by this module.

Work by Andrew Johnson

@li Import support for vxWorks 5.5 on m68k and powerpc from EPICS Base.

Work by Till Straumann

@li Add PCI Config space access functions devPCIConfigRead##() and devPCIConfigWrite##()
@li Add devPCIEnableInterrupt() and devPCIDisableInterrupt().
    - Linux: invoke the UIO irqcontrol callback function with a 1 or 0.
    - vxWorks: call intEnable or intDisable (enabled by default). (Dirk Zimoch)

Work by Dirk Zimoch

@li Rework of the Linux PCI bus scan to support PCI domains.
    Previously domain 0 was used implicitly.
@li Rework of the vxWorks/RTEMS PCI bus scan to allow wildcards in device search.
    This allows devPCIShow for all PCI devices like in Linux.
@li Fixes for 64 bit BARs.
@li vxWorks: use BAR address directly if sysBusToLocalAdrs does not support PCI.
@li Changes in devPCIShow to get nicer output.

Work by Michael Davidsaver

@li Add the pciconfread() iocsh function.
@li devLibPCIRegisterDriver()  is now a macro wrapping devLibPCIRegisterDriver2()
    which performs a consistency check on the size of the devLibPCI structure.
@li provide bswap16() and bswap32() for RTEMS PPC targets.  Previously omitted.
@li Change name format of Linux user "ISR" thread to include PCI BDF.


@subsection ver25 2.5 (May 2014)

@li Linux: possible string corruption in vallocPrintf()
      Found by Till Straumann
@li vxWorks: lookup symbols including sysBusToLocalAdrs at runtime.
      Work by Eric and Dirk Zimoch
@li RTEMS: Select no-op MMIO implementation for m68k (no special handling required)

@subsection ver24 2.4 (Oct. 2012)

@li Remove C++ style comments from epicsMMIODef.h and devcsr.h
@li Fix Issue preventing Custom PCI bus implementation. (Found by Dan Eichel)
@li Linux "ISR" thread stack size not correct (Fixed by Till Straumann)
@li Linux: Previous versions expected Linux kernel modules to leave gaps for un-mappable PCI BARs (I/O Ports).
    However, most existing kernel modules don't do this.  Add a flag to devPCIToLocalAddr() to specify
    how a device's kernel module does mapping.  The default is to map as in previous versions.
    (New behavior by Till Straumann)
    See documentation of devPCIToLocalAddr().

@subsection ver23 2.3 (Apr. 2012)

@li Include proper headers to enable memory barriers for vxWorks >= 6.6
@li Fallback to noop when vxWorks memory barriers are not available
@li Fix incorrect return code when connecting pci interrupts on vxWorks

@subsection ver22 2.2 (Sept. 2011)

@li linux: follow changes to /sys (needed for kernel >2.6.26)
@li pci: IOC shell functions added: pciread()
@li pci: vxworks translate PCI addresses
@li Build on vxWorks 6.8  (Thanks to Andrew Johnson)
@li pci: Make operations reentrant on RTEMS and vxWorks (previously was not oops.)
@li pci: Fix bug with devPCIBarLen on RTEMS and vxWorks.

@subsection ver21 2.1 (Jan. 2011)

@li Fix build issue with 3.14.12 with RTEMS pc386 (found by Jim Chen from Hytec)
@li Add notification of missed PCI interrupt events on Linux
@li Additional arguement 'count' for vmeread() to show blocks of registers
@li Add section to PCI Usage on x86 Port I/O
@li Add section to PCI Access in Linux concerning hardware requirements

@subsection ver20 2.0 (Sept. 2010)

@li Initial release.
