[RFC] libopenbios: Adapt CIF handling for ppc64

[Andreas Färber]

      On ppc64 neither long nor pointers can be used for the client interface.
Introduce new types prom_[u]arg_t to abstract this and add helpers
get_service() and arg2pointer() as well as format strings.

This should be "%016" for Sparc64 since long is 64 bits. Maybe these
should be moved to a common header instead.

Perhaps the the type of the return value should be const char *
instead, that may reduce the number of casts.

I don't think arg2pointer() has any effect for non-PPC64 hosts, so you
could also unconditionally use arg2pointer().

 This should be "%016" for Sparc64 since long is 64 bits.
The original code used %08 so I left it that way.
We could check #if BITS == 64.

  Maybe these
 should be moved to a common header instead.
In that case we need longer names - e.g., FMT_promarg.

 I don't think arg2pointer() has any effect for non-PPC64 hosts, so you
 could also unconditionally use arg2pointer().
OK.

That would change the output to decimal. Intentional? If I used  
FMT_argx, we'd introduce zero-padding.

cc1: warnings being treated as errors
../libopenbios/client.c: In function 'get_service':
../libopenbios/client.c:72:5: error: passing argument 1 of  
'arg2pointer' makes integer from pointer without a cast

A possible solution would be to always declare the service field as  
prom_uarg_t but then it cannot easily be inspected in gdb.

[PATCH v2 1/2] libopenbios: Adapt CIF handling for ppc64

[Andreas Färber]

      On ppc64, neither long nor pointers can be used for the client interface.
Introduce new types prom_[u]arg_t to abstract this and add helpers
get_service() and arg2pointer() as well as format strings.

v2:
* Move format strings to arch-specific headers.
* Always declare 'service' as prom_uarg_t for consistency.
  This keeps arch-specific code out.
* Let arg2pointer() return const char* to avoid casts. Suggested by Blue.
* Use zero-padded hexadecimal format string for unknown services.

 This should be "%016" for Sparc64 since long is 64 bits. Maybe these
 should be moved to a common header instead.
Yeah - I'd like to try and keep all of the format definitions in one 
place, such as include/arch/<arch>/types.h if possible.
