Re: [U-Boot-Users] [PATCH] PPC: Use r2 instead of r29 as global data pointer

Dear Rafal,

in message 47B85ECF.5080207@semihalf.com you wrote:

How about switching r14 (GOT ptr) to r13 in a similar way? Quite like the r2, r13 is a dedicated register (small data area purposes) and it would let us avoid using the -ffixed completely.

I have to admit that I don;t understand enough of these things to judge if R13 (listed as "small data area pointer") is really free for use for our purposes.

I can provide patches, but let me know your thoughts first.

I guess you already ran some tests? If you are sure about this, and if it really works, then please submit your patches!

Best regards,

Wolfgang Denk
