tools: mtk_image: use uint32_t for ghf header magic and version

2023-08-03T13:40:50+00:00

This patch converts magic and version fields of ghf common header
to one field with the type of uint32_t to make this header flexible
for futher updates.

tools: imagetool: Extend print_header() by params argument

2023-04-13T09:34:47+00:00

This allows image type print_header() callback to access struct
image_tool_params *params.

treewide: Drop image_header_t typedef

2022-09-29T20:07:57+00:00

This is not needed and we should avoid typedefs. Use the struct instead
and rename it to indicate that it really is a legacy struct.

tools: mtk_image: add support for nand headers used by newer chips

2022-09-23T19:09:16+00:00

This patch adds more nand headers in two new types:
1. HSM header, used for spi-nand thru SNFI interface
2. SPIM header, used for spi-nand thru spi-mem interface

The original nand header is renamed to AP header.

tools: mtk_image: split the code of generating NAND header into a new file

2022-09-23T19:09:16+00:00

The predefined NAND headers take too much spaces in the mtk_image.c.
Moving them into a new file can significantly improve the readability of
both mtk_image.c and the new mtk_nand_headers.c.

This is a preparation for adding more NAND headers.

tools: mtk_image: split gfh header verification into a new function

2022-09-23T19:09:16+00:00

The verification code of gfh header for NAND and non-NAND are identical.
It's better to define a individual function to reduce redundancy.

tools: mtk_image: add support for MT7621 NAND images

2022-07-13T21:03:37+00:00

The BootROM of MT7621 requires a image header for SPL to record its size
and load address when booting from NAND.

To create such an image, one can use the following command line:
mkimage -T mtk_image -a 0x80200000 -e 0x80200000 -n "mt7621=1"
-d u-boot-spl-ddr.bin u-boot-spl-ddr.img

tools: mtk_image: add an option to set device header offset

2021-03-20T20:24:27+00:00

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.

tools: mtk_image: add support for booting ARM64 images

2021-01-18T19:59:29+00:00

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

tools: mtk_image: replace strncpy(d, s, sizeof(d)) with snprintf()

2018-12-15T16:49:56+00:00

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.
