Hi Michael,

I am trying to bring up EHCI using the A64 driver. I configiured build
system to download a tar ball with linux kernel. However in the:
"CONFIG Linux" step I get this:
Makefile:621: arch/arm64/Makefile: No such file or directory
Which is natural since the source tree in depot isn't configured.
So the first questions is; when is the tree configured?
In the genode-allwinner repository, the Linux kernel's config step
happens via the 'a64_linux_generated' pseudo library [1].

https://github.com/genodelabs/genode-allwinner/blob/master/lib/mk/spec/arm_v8/a64_linux_generated.mk
If a target has 'a64_lx_emul' added to the 'LIBS' variable, the
corresponding import file implicitly adds the 'a64_linux_generated'
library [2].

https://github.com/genodelabs/genode-allwinner/blob/master/lib/import/import-a64_lx_emul.mk
So it should be enough to add the following line to a target.mk file:
LIBS += base a64_lx_emul
When processed by the Genode build system, the 'a64_linux_generated'
library leaves a readily configured Linux build directory at
<build-dir>/var/libcache/a64_linux_generated/.
Cheers
Norman
