qoriq: Problem with u-boot compilation (dual arch issue)

[Paweł Dembicki]

Hi everybody,

I am preparing support for the T4240RDB board. But I'm stuck with one problem:

Qoriq target is powerpc64. But  T4240RDB in u-boot is supported as
mpc85xx family and requires a 32-bit compiler.

I tried setting OpenWrt config:  EXTRA_TARGET_ARCH to y and
EXTRA_TARGET_ARCH_NAME to powerpc32. But it didn't work:

I see two possible solutions:
1. Compile u-boot with regular powerpc compiler
2. Fix settings in powerpc64 linker to allow build 32-bit arch binary.

Can I ask for help with it?
