A number of headers define functions as "extern inline" which is
causing problems with gcc5. The reason is that starting with
version 5.1, gcc defaults to the standard C99 semantics for the
inline keyword.
Under the traditional GNU inline semantics, an "extern inline"
function would never create an external definition, the same
as inline *without* extern in C99. In C99, and "extern inline"
definition is simply an external definition with an inline hint.
In short, the meanings of inline with and without extern are
swapped between GNU and C99.
The upshot is that all these definitions in header files create
an external definition wherever those headers are included,
resulting in multiple definition errors at link time.
Changing all these functions to "static inline" fixes the problem
since this works as desired in all gcc versions. Although the
semantics are slightly different (a static inline definition may
result in an actual function being emitted), it works as intended
in practice.
This patch also removes extern prototype declarations for the
changed functions where they existed.

The dram initialization sequence should be in order.
This patch add mb for the dram intialization code to make
sure the compiler do not disorder the code.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

The compile error was caused by a recent patch. Affected platforms -
M5253DEMO.h, M5253EVBE.h, and M54455EVB.h. Adding the _IO_BASE
automatically defined to 0 in asm-m68k/io.h if it isn't set in
platform configuration file.

virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.
However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

Also add CONFIG_PHYS_64BIT on powerpc to deal with 32-bit ppc's
that have larger physical addresses like 44x, 85xx, and 86xx.

map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.
This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

This adds implementations of __raw_read[bwl] and __raw_write[bwl] to
m68k, ppc, nios and nios2. The m68k and ppc implementations were taken
from Linux.

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.
