[PATCH 1/2] kernel-fitimage: support 64 bits address

[Jamin Lin]

The default value of address-cells is "1", so the generated "its" file
only supports 32bits address for kernel FIT image.
However, some platforms may want to support 64bits address
of UBOOT_LOADADDRESS and UBOOT_ENTRYPOINT.
Therefore, adds a variable to support both 64bits and 32bits address cells.

By default, the address-cell is "1" which is used for 32bits load address.
If users would like to use 64bits load address, users are able to
set as following for "0x400000000" 64bits load address.
1. FIT_ADDRESS_CELLS = "2"
2. UBOOT_LOADADDRESS= "0x04 0x00000000"

This line should not be there. It looks like  you generated your patches
from a poky repository where this patch landed via combo-layers, but it
just doesn't make sense as an oe-core patch. Also, that SHA-1 does not
exist in the public oe-core repository.

I removed that line while applying the patch for testing, so you
don't need to resend for this time, but please make sure you generate
your patches from an oe-core repository in the future.

The same applies to patch 2/2.

Best regards,
Luca

Thanks for your review and correct me.

I should create a patch based on an openembedded-core repository rather than a poky repository.
