Currently they are using an old 2.6.20 kernel with no problems. They are trying to use a 3.x kernel and the system does not boot. I sent them a patch to use ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR instead of the hardcoded PHYS_OFFSET on the ARCH_EP93XX platform but the 0xf0000000 physical address still does not work. The patched kernel (3.17.2) does boot on boards with the SDRAM located at physical address 0x00000000 and 0xc0000000. These boards boot with the following information in the boot log: Memory: 60056K/65536K available (3432K kernel code, 185K rwdata, 976K rodata, 133K init, 107K bss, 5480K reserved) Virtual kernel memory layout: vector : 0xffff0000 - 0xffff1000 ( 4 kB) fixmap : 0xffc00000 - 0xffe00000 (2048 kB) vmalloc : 0xc6800000 - 0xff000000 ( 904 MB) lowmem : 0xc0000000 - 0xc6000000 ( 96 MB) modules : 0xbf000000 - 0xc0000000 ( 16 MB) .text : 0xc0008000 - 0xc0456274 (4409 kB) .init : 0xc0457000 - 0xc04785cc ( 134 kB) .data : 0xc047a000 - 0xc04a8700 ( 186 kB) .bss : 0xc04a8700 - 0xc04c365c ( 108 kB) Would the 0xf0000000 physical address be a problem since it's located in the vmalloc range? Any ideas on what to do? Following is a copy of the patch I sent them to test.
