sndnvaps commented 8 years ago

in some old device , it does not support dtb(device tree blob), just have atags ... how can it work with it ..

do you have plan to backport atags support for mako ... or the other old kernel (who does not have the dtb support ) @Tasssadar

when i use kexec --load --mem-min=0x85000000 --command-line='$(cat /proc/cmdline)' --ramdisk=./ram_disk.img --atags-addr=0x0x00000100 ./aries-boot.img-zImage

i got this segment info 
kernel: 0xb5fd2008 kernel_size: 713640
kexec_load: entry = 0x80208000 flags = 280000
nr_segments = 3
segment[0].buf   = 0x114f1f0
segment[0].bufsz = cc
segment[0].mem   = 0x80201000
segment[0].memsz = 1000
segment[1].buf   = 0xb5fd2008
segment[1].bufsz = 713640
segment[1].mem   = 0x80208000
segment[1].memsz = 714000
segment[2].buf   = 0xb6e55008
segment[2].bufsz = 1746f0
segment[2].mem   = 0x81e4e000
segment[2].memsz = 175000
