[PATCH 0/2] Set reasonable defaults for WKS_FILE value

[PATCH 0/2] Set reasonable defaults for WKS_FILE value

[Anton Mikanovich]

Current default for WKS_FILE supposed to be used on targets with EFI
support, so targets with architectures riscv64 and mipsel will fail on
using it. Set some other WKS_FILE defaults supported by that targets.

This change requires COREBASE variable set by meta layer (just like it
is implemented in OE). This variable specifies the parent directory of
meta layer and was used in bitbake and Isar code without being
initialized.

[PATCH 1/2] meta: Add missing COREBASE variable

[Anton Mikanovich]

This variable specifies the parent directory of meta layer and was used
in bitbake and Isar code without being initialized.
Setting this variable will fix the usage of WKS_FILES from default WIC.

[PATCH 2/2] wic: Set default WKS_FILE for non efi targets

[Anton Mikanovich]

As riscv64 and mipsel are not supported by grub-efi set other default
WKS_FILE values for them.

This part was wrong, breaking downstream layers: overrides win over
normal assignments. So,

WKS_FILE = "my-file"

will lose in the face of the above. Fixing...

Hello Jan,

Thanks for checking. This change was introduced as a hotfix for the 
installer
image creation of riscv64 and mipsel targets with no WKS_FILE provided in
machine config (to make it works just like any other arch). As this 
syntax is
wrong we need to find some other style for the fix.
