I have question concerning the memory configuration variables in the
MIPS/Linux
codebase.  I am working on a board that has 64Mbytes (0x400 0000) of
SDRAM.  We
are using an R4000 core and have the memory map setup so that KSEG0 &
KSEG1 both
map to address 0x0 in physical memory.  On our embedded system we are
going to hard
code the variable mips_memory_upper (This eventually is stored in
memory_end).  My
question is what I should initialize the value to?  Do I treat the top
of memory as KSEG1
+ 64Mbytes? (i.e., 0xA400 0000) or do I initialize it realative to 0?
If anybody has any
insights in this area, any information would be greatly appreciated.

Thanks,
Jeff
