sparc: fix sparse warnings in arch/sparc/prom for 32 bit build

2011-01-03T20:15:12+00:00

Fix following sparse warnings:
arch/sparc/prom/bootstr_32.c:32:35: warning: Using plain integer as NULL pointer
arch/sparc/prom/memory.c:61:13: warning: symbol 'prom_meminit' was not declared. Should it be static?
arch/sparc/prom/misc_32.c:74:1: error: symbol 'prom_halt' redeclared with different type (originally declared at arch/sparc/include/asm/oplib_32.h:67) - different modifiers
arch/sparc/prom/ranges.c:16:26: warning: symbol 'promlib_obio_ranges' was not declared. Should it be static?
arch/sparc/prom/ranges.c:17:5: warning: symbol 'num_obio_ranges' was not declared. Should it be static?
arch/sparc/prom/ranges.c:39:1: warning: symbol 'prom_adjust_ranges' was not declared. Should it be static?
arch/sparc/prom/ranges.c:69:13: warning: symbol 'prom_ranges_init' was not declared. Should it be static?
arch/sparc/prom/tree_32.c:286:22: warning: Using plain integer as NULL pointer
arch/sparc/prom/tree_32.c:286:38: warning: Using plain integer as NULL pointer

None of the warnings indicated any serious issues.

We are now sparse clean for 32 bit build in arch/sparc/prom.

sparc: Write to prom console using indirect buffer.

2010-12-01T04:15:58+00:00

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.

sparc: Pass buffer pointer all the way down to prom_{get,put}char().

2010-11-30T22:33:29+00:00

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.
