Re: [U-Boot] [Patch V3 2/4] [MIPS] add mips64 support in mips head files

2012-08-23 Thread Daniel Schwierzeck 
2012/8/20 Zhizhou Zhang etou...@gmail.com:
 The most important difference between mips32 and mips64 is the address
 space. changes in addrspace.h and io.h are for this sake. And this patch
 add cache discribe struct in cache.h, and make compatible to mips64 of
 some types in posix_types.h.
