Hi Isar team,

I am currently considering using ISAR= to build a system with the following architecture:

* Kernel: ARM64 = (64-bit)
* rootfs: ARM32 (32-bit)

I understand that the ISAR_ENAB= LE_COMPAT_ARCH option allows for the building of
some 32-bit packages, b= ut in this case, I want to build all packages as 32-bit.

Could you p= lease let me know if this somewhat special configuration of "32-bit ro= otfs
with 64-bit kernel" is supported for cross-architecture buildi= ng within ISAR?
If it is possible, I would greatly appreciate it if you = could provide the specific steps,
such as the necessary settings in loca= l.conf.

Thanks!

Best regards,
Hiro
