Weijie Gao cfd48ec4dc tools: mtk_image: add an option to set device header offset
This patch adds an option which allows setting the device header offset.
This is useful if this tool is used to generate ATF BL2 image of mt7622 for
SD cards.

Fabien Parent 44165e4c67 tools: mtk_image: add support for booting ARM64 images
mkimage is only able to package aarch32 binaries. Add support for
AArch64 images.

One can create a ARM64 image using the following command line:
mkimage -T mtk_image -a 0x201000 -e 0x201000 -n "media=emmc;arm64=1"
-d bl2.bin bl2.img

Andy Shevchenko 74473ed0cf tools: mtk_image: replace strncpy(d, s, sizeof(d)) with snprintf()
Starting from version 8 the GCC, i.e. C compiler, starts complaining about
possible '\0' terminator loss or, as in this case, garbage copy.

In function ‘mtk_image_set_gen_header’,
    inlined from ‘mtk_image_set_header’ at tools/mtk_image.c:733:3:
tools/mtk_image.c:659:2: warning: ‘strncpy’ specified bound 12 equals destination size [-Wstringop-truncation]
  strncpy(hdr->boot.name, bootname, sizeof(hdr->boot.name));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In function ‘mtk_brom_parse_imagename’,
    inlined from ‘mtk_image_check_params’ at tools/mtk_image.c:388:9:
tools/mtk_image.c:325:5: warning: ‘strncpy’ specified bound 32 equals destination size [-Wstringop-truncation]
     strncpy(lk_name, val, sizeof(lk_name));
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Replace it with snprintf() to tell compiler how much room we have in the
destination buffer for source string.
