I am working on pxa300 based development board and using Linux 2.6.34.
This Linux kernel already has support for following boards
1. zylonite_pxa300
2. cm-x300
3. colibri-pxa300
4. littleton
My doubt is that pxa300 based boards are using "0xa0000000" as DDRAM
base and PHYS_OFFSET is also defined in
"arch/arm/mach-pxa/include/mach/memory.h" as 0xa0000000.
But in our board DDR is mapped in 0x80000000. Does it make any
problem?. Because after mmu is turned ON, my board is hanging.
"zreladdr-y := 0x80008000" is defined in
"arch/arm/mach-pxa/Makefile.boot" file .
my machine_desc is as follows
.phys_io = 0x40000000,
.io_pg_offst = (io_p2v(0x40000000) >> 18) & 0xfffc,
.boot_params = 0x80000100,
With Thanks
