[U-Boot-Users] Compiling relocatable code and DATA for PPC

[Kate Alhola]

I have been trying to find out right options to configure gcc to produce
data and code
relocatable code for mpc5xx. The -fpic -meabi -msdata=eabi -G10000
does code as relocatable but data is still absolute. -fpic is incompatible
with -msdata=eabi so they can't be used at same time.

based on gcc documentations -msdata=eabi -G10000 should
put data so long that it is smaller than valu give in -G option
to relative to r2 or r3 but i have not suceeded to do it.

I have been using gcc for producing absolute code for PPC many, many years
but now i have need to load dynamically code for non mmu PPC (mpc555).
All examples that i have found uses static addresses. Also using
google i have not found any answers.

I have tried many forums to find answer but i am still trying to find
it. Also i am happy to get pointers to forums/places where i can continue
my search.
