dump boot.im

prints informataion like size and offset of kernel and ramdisk from a boot.img

code is based around boot_img_hdr from bootimg.h

struct boot_img_hdr
{
    uint8_t magic[BOOT_MAGIC_SIZE];

    uint32_t kernel_size;
    uint32_t kernel_addr;

    uint32_t ramdisk_size;
    uint32_t ramdisk_addr;

    uint32_t second_size;
    uint32_t second_addr;

    uint32_t tags_addr;
    uint32_t page_size;
    uint32_t unused[2];

    uint8_t name[BOOT_NAME_SIZE];

    uint8_t cmdline[BOOT_ARGS_SIZE];

    uint32_t id[8];

    uint8_t extra_cmdline[BOOT_EXTRA_ARGS_SIZE];
