This patch brings the following changes: * Documentation about how to customize the wic image for N1SDP * Introduce a custom wks and grub.cfg file for N1SP when building with `DISTRO_FEATURES += "arm-autonomy-host"` to include Xen artefacts and boot option. * Introduce a mechanism to include extra global settings for machines defined in meta-arm-bsp when building with `DISTRO_FEATURES += "arm-autonomy-host"`.

Customizing Arm Autonomy Host image layout for N1SDP
When buiding with DISTRO_FEATURES += "arm-autonomy-host" the user can
perform a couple of customizations in the generated wic image:
-
Set the guest partition size (default: 4iG) via
GUEST_PART_SIZEandGUEST_PART_SIZE_UNIT(M or G) variables to be set in any conf file. The value of these variables should be aligned with the sum of all XENGUEST_IMAGE_DISK_SIZE set for the guests. By default, LVM2 metadata is 1 MiB per physical volume, hence it needs to be taken into account when setting GUEST_PART_SIZE. -
The wic image partition layout and contents with a custom wks file via
ARM_AUTONOMY_WKS_FILEvariable (default: arm-autonomy-n1sdp-efidisk.wks.in which is affected by GUEST_PART_SIZE, GUEST_PART_SIZE_UNIT and GRUB_CFG_FILE variables). -
Custom grub.cfg file via
GRUB_CFG_FILE(default: arm-autonomy-n1sdp-grub.cfg) variable to be set in any conf file. The full path or relative toARM_AUTONOMY_WKS_FILEshould be set.
The arm-autonomy-n1sdp-efidisk.wks.in and arm-autonomy-n1sdp-grub.cfg files
are located at meta-arm-autonomy/dynamic-layers/meta-arm-bsp/wic.
Other variables can also be custmized to set what files need to be included
in the wic image boot partition. Please refer to
meta-arm-autonomy/dynamic-layers/meta-arm-bsp/conf/machine/n1sdp-extra-settings.inc
for more details.
