* scripts/gen_image_generic.sh: fix more shellcheck warningsPetr Štetiar2020-07-111-4/+3
| | | | | | | | | | | | | | | | | | Fixes following shellcheck warnings: In scripts/gen_image_generic.sh line 20: cyl=$(( (KERNELSIZE + ROOTFSSIZE) * 1024 * 1024 / (head * sect * 512))) ^-^ SC2034: cyl appears unused. Verify use (or export if used externally). -- In scripts/gen_image_generic.sh line 34: [ -n "$PADDING" ] && dd if=/dev/zero of="$OUTPUT" bs=512 seek="$(($ROOTFSOFFSET + $ROOTFSSIZE))" conv=notrunc count="$sect" ^-----------^ SC2004: $/${} is unnecessary on arithmetic variables. -- In scripts/gen_image_generic.sh line 35: mkfs.fat -n kernel -C "$OUTPUT.kernel" -S 512 "$(($KERNELSIZE / 1024))" ^---------^ SC2004: $/${} is unnecessary on arithmetic variables.

* scripts/gen_image_generic.sh: replace -o with if/&&Rosen Penev2020-07-111-2/+2

* x86: generate EFI platform bootable images李国2020-03-311-2/+8
| | | | | | | | | | | | | | | | | Add EFI platform bootable images for x86 platforms. These images can also boot from legacy BIOS platform. EFI System Partition need to be fat12/fat16/fat32 (not need to load filesystem drivers), so the first partition of EFI images are not ext4 filesystem any more. GPT partition table has an alternate partition table, we did not generate it. This may cause problems when use these images as qemu disk (kernel can not find rootfs), we pad enough sectors will be ok.

* build: label kernel and rootfs ext4 volumesYousong Zhou2019-11-031-1/+1
| | | | | | | | | | | UUID of ext4 volumes generated by make_ext4fs are determined by volume label and it will all be 57f8f4bc-abf4-655f-bf67-946fc0f9f25b when label is empty Labeling them does not make them unique but tools like block command from fstools have a better chance differentiating them Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
* scripts/gen_image_generic.sh: fail on errorsStijn Tintel2019-03-271-1/+1
| | | | | | | | | | | The script always exits with value 0, even if some of the commands fail. This can potentially create broken, unbootable images, e.g. when make_ext4fs fails due to TARGET_KERNEL_PARTSIZE being too small for the kernel. Avoid this by failing the script when any command fails. Acked-by: Jo-Philipp Wich <jo@mein.io> Acked-by: Petr Štetiar <ynezz@true.cz> Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
