Just curious. How does one normally build U-Boot or kernel for ARM
devices in Debian Jessie?
The official .deb packages are built natively in Debian, not cross
compiled.
For user's local cross builds there is work on going to provide
official packaged cross compilers but those are not widely available
enough (and somewhat in flux, and not in a stable release yet) to rely
on for the sunxi-tools package builds.
For non-packaging work I personally tend to use the Linaro compilers
and will switch to the officially package cross-compilers once they are
more reliably available.
I think i'm using the embdebian cross toolchain (unless it has been
added to jessie) and I'm not unhappy with it so far. Though I do only
crossbuild the kernel and u-boot and my own little userspace app.
The only reason gcc/cpp are required are to strip the embedded Ruby code out
before handing to the assembler, we can achieve the same by opening a multiline
comment around the ruby instead. Care needs to be taken not to close the
comment prematurely hence "*/" is written in the one place it is used as
"\x2a/" (i.e. encoding the * in hex). Having done this we can pass the .S file
We could probably do this even without relying on magic ASCII numbers.
Using something like printf("%s%s", "*", "/"). But since I'm not aware
of any relevant non-ASCII compatible system, either way is fine.
Right, I also considered a function comment(fmt, ...) which wrapped wha
t it was given in the /* */ in some opaque way but for the one instance
in this code I thought it wasn't worth it.

Thanks.
