[OE-core v1 PATCH 0/5] aarch64 changes for meta layer

[OE-core v1 PATCH 0/5] aarch64 changes for meta layer

[Naresh Bhat]

I am adding the support of aarch64 to LUV OS Distribution project.
The luv-yocto project is based on poky distribution.

https://01.org/linux-uefi-validation

While adding support I find that these are the few meta layer changes,
which I have been asked to upstream. If we merge these changes into
openembedded-core it will be more helpful to maintain the minimum set
patches at dependency projects like luv-yocto.

Changes since V0:[RFC series]
- Include all the chages suggested by Bernhard Reutner-Fischer
- Add grub recipe changes suggested by Burton Ross

Naresh Bhat (5):
  bootimg: Add support to install Image
  syslinux: Remove bootimg dependency on aarch64
  bootimg: Skip build iso image for aarch64
  grub: Update grub git recipe
  grub-efi: Add to support to install grubaa64 efi

[OE-core v1 PATCH 2/5] syslinux: Remove bootimg dependency on aarch64

[Naresh Bhat]

Remove the bootimg dependency as syslinux for aarch64. The reason to skip the syslinux package
- syslinux package contains x86 assembly code. Hence it cannot be compiled on aarch64.
- There is no BIOS on aarch64 to answer syscalls.

How about something simpler like:

EXTRABOOTIMGDEPS = ""
EXTRABOOTIMGDEPS_x86 = "${MLPREFIX}syslinux:do_populate_sysroot"
EXTRABOOTIMGDEPS_x86-64 = "${MLPREFIX}syslinux:do_populate_sysroot"

?

This commit message isn't up to the job. You listed some things you
changed but didn't say why these are necessary or how this helps. Some
of the changes in here may be better split up a bit too, there seems to
be a lot going on.

Why do we need brokensep? It appears to work at the moment?

You need both an export and a CACHED_CONFIGUREVARS?

Thank you very much.  Yes, it is more simple. I will test the same
implementation and make the changes in the next series.

As previously asked, why does this only affect aarch64 and not all not COMPATIBLE_HOST ?
Shouldn't you instead set NOISO to 1 for !COMPATIBLE_HOST ?

I will appreciate if you point me to the changes which needs to be split

Yes, this is the reason I need brokensep.  The recipe fails to build on our
luvOS distribution.

Right now the recipe builds for PC on x86 architecture. On x86 architecture
it is required to update.

My mistake, If I understand properly the native recipe get build in first
place.  There is no need to add depends.
