Convert MMIO accesses of non-internal PCI-based programmers to be endian-agnostic
Convert all PCI-based external programmers to use special little-endian
accessors for all MMIO regions of PCI devices. This patch does _not_
touch the internal programmer (which is PCI-based as well).
Huge thanks go to Misha Manulis who worked with me to create a first
version of this patch for the satasii programmer based on modification
of generic code.
Huge thanks also go to Segher Boessenkool for suggesting the pci_mmio_
prefix for the abstraction layer.
NOTE to package maintainers: With this patch, compilation and usage of
flashrom should be safe on x86, x86_64, MIPS (little and big endian) and
PowerPC (big endian).
The internal programmer is disabled on non-x86/x86_64 (but it
compiles). The atahpt, nic3com, nicnatsemi, nicrealtek and rayer_spi
can not be compiled on non-x86/x86_64 because port space I/O is
not (yet) supported. Please compile with default settings on
x86/x86_64 and with the following settings on all other architectures:
make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no CONFIG_NICNATSEMI=no
CONFIG_RAYER_SPI=no
Corresponding to flashrom svn r1111.
