HOW TO USE:

Unpack boot/recovery(.img) support dtb(dt.img):

	./mkboot name.img namefolderout

EXAMPLE
	./mkboot recoveryksuamg5.img ksuamg
	Unpack & decompress recoveryksuamg5.img to ksuamg
	  kernel         : /home/xiaolu/work/initramfs/s4/e330s/ksuamg5/zImage
	  ramdisk        : /home/xiaolu/work/initramfs/s4/e330s/ksuamg5/ramdisk.gz
	  page_size      : 2048
	  base_addr      : 0x00000000
	  kernel size    : 6911360
	  kernel_addr    : 0x00008000
	  ramdisk_size   : 2685222
	  ramdisk_addr   : 0x02000000
	  second_size    : 0
	  second_addr    : 0x00f00000
	  dtb_size       : 1427456
	  tags_addr      : 0x01e00000
	  cmdline        : console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F
	Unpack completed.

Repack boot/recovery(.img) support dtb(dt.img):

	./mkboot namefolderout newimgname.img

EXAMPLE
	./mkboot ksuamg5 recovery.img
	mkbootimg from ksuamg5/img_info.
	  kernel         : /home/xiaolu/work/initramfs/s4/e330s/ksuamg5/zImage
	  ramdisk        : /home/xiaolu/work/initramfs/s4/e330s/ksuamg5/new_ramdisk.gz
	  page_size      : 
	  base_addr      : 0x00000000
	  kernel size    : 6911360
	  kernel_addr    : 0x00008000
	  ramdisk_size   : 2685222
	  ramdisk_addr   : 0x02000000
	  second_size    : 
	  second_addr    : 
	  dtb_size       : 1427456
	  dtb_img        : dt.img
	  tags_addr      : 0x01e00000
	  cmdline        : console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F
	Kernel size: 6911360, new ramdisk size: 3416778, recovery.img: 11759616.
	recovery.img has been created.
