[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"

[PATCH 2/2] uboot-sign: support 64bits address

[Jamin Lin]

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

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.

Since this adds new variables, could you send patches to the
documentation please to document them?

I did also wonder if there was some way we could combine and share some
of this fit image information since we appear to have two variables
with different names encoding the same info here :/. Maybe that is
something we could fix or improve in a later patch?

I'm kind of living in hope we can simplify some of these different
places to share code ultimately.

Cheers,

Richard
