Fbdev's main header file, , includes to get
declarations for I/O helper functions. From these declaratons, later
defines framebuffer I/O helpers, such as fb_{read,write}[bwlq]() or
fb_memset().
The framebuffer I/O helpers depend on the system architecture and
will therefore be moved into .
Implement framebuffer I/O helpers, such as fb_read*() and fb_write*(),
in the architecture's header file or the generic one.
The general solution is to use regular I/O functions, such as
__raw_readb() or memset_io(). This has been the most-common case so
far.
The implementations for arc, ia64,
The code uses writel() and similar I/O-memory helpers. Include
the header file to get the declarations.

Fbdev provides helpers for framebuffer I/O, such as fb_readl(),
fb_writel() or fb_memcpy_to_fb(). The implementation of each helper
depends on the architecture. It's still all located in fbdev's main
header file . Move all of it into each archtecture's
, with shared code in .
The first patch a
The code uses readl() and writel(). Include the header file to
get the declarations.
