595a251c07 sparc: Write to prom console using indirect buffer.
sparc64 systems have a restriction in that passing in buffer
addressses above 4GB to prom calls is not reliable.

We end up violating this when we do prom console writes, because we
use an on-stack buffer to translate '\n' into '\r\n'.

So instead, do this translation into an intermediate buffer, which is
in the kernel image and thus below 4GB, then pass that to the PROM
console write calls.

On the 32-bit side we don't have to deal with any of these issues, so
the new prom_console_write_buf() uses the existing prom_nbputchar()
implementation.  However we can now mark those routines static.

Since the 64-bit side completely uses new code we can delete the
putchar bits as they are now completely unused.

e62cac1fd0 sparc: Pass buffer pointer all the way down to prom_{get,put}char().
This gets us closer to being able to eliminate the use
of dynamic and stack based buffers, so that we can adhere
to the "no buffer addresses above 4GB" rule for PROM calls.

8d1255627d of/sparc: convert various prom_* functions to use phandle
Rather than passing around ints everywhere, use the
phandle type where appropriate for the various functions
that talk to the PROM.

efe6c3dd8b sparc: Use sparc64 version of prom/printf.c
Use sparc64 version of prom/printf.c.

The only differences for sparc32 is that prom_printf is no longer
exported for modules which should be OK.

5110bd21b8 sparc: remove CONFIG_SUN4
While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.

And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

a439fe51a1 sparc, sparc64: use arch/sparc/include
The majority of this patch was created by the following script:

***
ASM=arch/sparc/include/asm
mkdir -p $ASM
git mv include/asm-sparc64/ftrace.h $ASM
git rm include/asm-sparc64/*
git mv include/asm-sparc/* $ASM
sed -ie 's/asm-sparc64/asm/g' $ASM/*
sed -ie 's/asm-sparc/asm/g' $ASM/*
***

The rest was an update of the top-level Makefile to use sparc
for header files when sparc64 is being build.
And a small fixlet to pick up the correct unistd.h from
sparc64 code.
