Hi Peter,
I have tried cleaning up a bit the usage of string functions in arch/x86/boot/.
I have created x86/boot/string.h which all the callers can include and by default they get the built in definition of memcpy, memset and memcmp. Those who want to use optimized version of these functions, need to #undef respective macro and link again the approprate string.c file which provides the function definition.
After this change I am planning to include x86/boot/string.h in purgatory code and get built-in definitions of memcpy, memset and memcmp.
There seem to be lot of magic going on in arch/x86/boot/. I do not claim to understand it all. Hopefully above changes do not break anything.
Please have a look.
Thanks Vivek
