Adding basic support modeled after the Freescale/NXP
T1040RDBD4 board.

This target is used to support testing of the bootlin e5500
toolchain.

Just noticed I should have added myself to configs/qemu_ppc64_e5500_defconfig

This arch seems like it had good support back to QEMU 2.0.0.  However,
I'll be submitting a bootlin e6500 arch variant toolchain but I'm
still working out what version of QEMU can even boot that arch.  As of
2.11.x support hasn't been merged.

(Working on pull request for e5500 testing in the toolchain-builder repo now)

I don't get it. In the same paragraph you say "it had good support back
to Qemu 2.0.0" and  "as of 2.11.x support hasn't been merged".

Could you clarify ?

As you mentioned, missing entry for the defconfig file itself.

E500, while it's E5500 ?

You need an option here to specify the version of the kernel headers
being used.

The Qemu emulation doesn't support emulating some hard drive, to use a
more regular ext4 setup ?

Thanks!

The e5500 has good support in 2.0.0 but I've been looking at adding a
new e6500 which does not.

e5500 is a variant of e500 base architecture.  I can add to my comment
to express that.

I debated on this.  I'll have to add more support to the kernel
fragment to enable the options so I can mount it.  I'm good either
way.
