[U-Boot] Microblaze and Sparc boards are broken because of common timer func

[U-Boot] Microblaze and Sparc boards are broken because of common timer func

[Masahiro Yamada]

Hello, Rob, Tom, Michal, Daniel.

Commit 8dfafdde88eb (Introduce common timer functions)
broke Microblaze and Sparc boards.

(I can notice broken boards because I quite often build all boards
for the test of Kbuild porting.)

This should be fixed by this patch - at least for microblaze.

commit 65ba7add0d609bbd035b8d42fafdaf428ac24751
Author: Rob Herring <rob.herring@calxeda.com>
Date:   Fri Nov 8 08:40:43 2013 -0600

    time: add weak annotation to timer_read_counter declaration

    A weak annotation is needed in order to prevent link errors when
    get_ticks is overridden. This fixes sandbox build.

    Signed-off-by: Rob Herring <rob.herring@calxeda.com>

Thanks,
Michal

No.
I tried both the current u-boot/master and commit 65ba7add0d,
but Microblaze board failed with the same error message.

Look at this log - uboot section.

Which toolchain do you use?

Thanks,

It builds for me with 4.8.0 from kernel.org, but I had to disable
systemace driver otherwise I get this error:

yes. That's my behaviour too when I use this toolchain.
I have to ping toolchain people to find out status of stack support
in mainline gcc.

Microblaze crosstools I use is available at:
http://dev.gentoo.org/~vapier/u-boot/microblaze.tar.xz

Before commit 8dfafdde88eb, I could build the microblaze-generic
board with it.
But I can't build for the current u-boot/master.

Not sure if Mike maintains this toolchain.

You can use this one and follow Rob's comments.

Stefan Roses told me about this pre-built cross tool in a thread:
http://u-boot.10912.n7.nabble.com/Suggestion-for-building-all-boards-td165285.html

Accoding to this thread, it was built by Mike Frysinger.

Worked for me.
OK. Going forward I will use this. Thanks!

Well, why is the assembler part failing?  And what is the toolchain
people should use here?

That's not question to me but to our toolchain guys what it is missing
in the mainline gcc. I have sent them an email. Will see what I get.

I do use these two toolchains[1] depends if you want to compile little
or big endian targets. Mainline u-boot, because of ll_temac driver,
must be compiled by big endian toolchains.
