boot-directdisk: avoid loop in MBR disk signature generation

2013-10-04T17:25:05+00:00

Instead of looping until the generated signature is non-zero, just
return 'ffffffff' if it's zero. This avoids an infinite loop if the
generated signature is always zero.

boot-directdisk: ensure generated MBR disk signature is non-zero

2013-09-30T21:03:23+00:00

A zero MBR disk signature is generally seen as no signature and
another partitioning program might install a new signature.

boot-directdisk.bbclass: Fix media generation problems with vmdk

2013-09-26T16:27:23+00:00

The various populate methods need to accept a path as an argument vs
using hard expanded variables.  In the case of the boot-directdisk
class it uses a different path for HDDDIR but it gets eclipsed by the
the class definition at the point in time ${HDDDIR} gets expanded.

The logical fix is to pass the arguments to the functions as opposed
to using globally expanded variables from the class definitions.

This patch changes 3 things:
1) syslinux_hddimg_populate takes an argument for the destination
2) syslinux_iso_populate takes an argument for the destination
3) populate is changed to boot_direct_populate because there
   was a conflict with it overriding the populate in bootimg.bbclass

boot-directdisk: Allow for EFI-only boot direct disk images

2013-09-14T07:26:44+00:00

    Condition building PCBIOS legacy images on MACHINE_FEATURES containing "pcbios"
    or not containing "efi". This ensures existing BSPs will continue to get the
    old PCBIOS legacy-only images. New BSPs can add "efi", "pcbios", or both. The
    images created likewise support one or the other or both.

boot-directdisk: use awk instead of echo -ne for dash compatibility

2013-07-23T14:22:38+00:00

The echo command is a dash shell built-in and does not support the
-n and -e options so use awk instead.

This fixes the partition table being corrupted when writing the MBR
disk signature into the image.

boot-directdisk: allow specifying custom MBR disk signature

2013-07-11T23:07:24+00:00

This introduces a DISK_SIGNATURE variable that allows controlling the
32-bit MBR disk signature. By default it is set to an automatically
generated disk signature but it may by overridden in the image recipe
by setting DISK_SIGNATURE to a 8 digit hex string.

This DISK_SIGNATURE variable can also be used in the image recipe to
specify the root by UUID using:
SYSLINUX_ROOT = "root=PARTUUID=${DISK_SIGNATURE}-02"

Specifying the root by UUID allows the kernel to locate the root
filesystem even if the device name changes (e.g. /dev/hda2, /dev/hdb2 or
/dev/sdb2 instead of /dev/sda2) due to differences in hardware
configuration.

boot-directdisk: Scope HDDDIR and HDDIMG variables to avoid conflicts

2013-05-15T21:05:07+00:00

These variables should not be shared with other image classes.
The bootimg class also has an HDDDIR variable that could be overwritten
if executing concurrently in the same image recipe.

boot-directdisk/bootimg/image-vmdk: remove more nostamps for image generation

2013-05-10T09:25:01+00:00

We have removed the nostamps for do_rootfs and do_build, so it seems
reasonable to remove the stamps for do_bootimg, do_bootdirectdisk and
do_vmdkimg.

The current problem is that the do_vmdkimg always re-run, but the
do_rootfs may not, so the code like below in the do_rootfs function
doesn't re-run and cause problems (the symlink exists when the
do_vmdkimg creates the symlink again):

    if d.getVar('IMAGE_LINK_NAME', True):
        cmds += "\trm -f ${DEPLOY_DIR_IMAGE}/${IMAGE_LINK_NAME}.*"
