[U-Boot] Remove sparc archiecture?

[Simon Glass]

Hi,

It looks like sparc has no maintainer and has not been converted to
generic board. Should we remove it?

Regards,
Simon

Well, not quite "no maintainer", but... Daniel?  SPARC is in need of
some work (and possibly a new toolchain too, I stopped building it all
the time due to a false positive warning the 3.4.4 toolchain I have
gives).  Thanks!

I see generic board work for SPARC

but, Daniel was not responding...


Perhaps, replace the maintainer if Francois agrees?

I regret to say that I've been too busy last two years and I don't see a 
change during 2015 either.

I would not like to see the SPARC port removed now that the LEON 
community grows as new LEON3 and LEON4 chips comes to market. WIth 
multi-core and higher frequency there is a growing interest in u-boot 
from the LEON community.

Nowadays there are LEON GCC targets mcpu=leon,leon3,leon3v7 so it should 
be possible to setup a working toolchain based on GCC-4.9 which we use 
for Linux and RTEMS. In the past I've used a GCC-4.4 toolchain from 
Cobham Gaisler.

If Francois agrees it is probably a good idea to let him take over the 
SPARC as he has put work into both BSP and architecture. Although I 
would like to acknowledge my interest in u-boot and I hope and believe 
that my efforts will be resumed in the future. Francois, if you feel it 
is too much a temporary replacement could also be an option if the 
u-boot project allows it.

Daniel Hellstrom

Yes, I am willing to take over as maintainer until such time that Daniel is ready
to resume his effort in future. We are investing in the LEON as archtecture and
would like to see U-Boot support for SPARC continuing into the future.

Daniel, I would just like to ask if you could stay on as an advisor, if at all possible.
I have only access to one LEON3FT board at the moment and may require advice
on other devices as time goes by.  I will try to keep questions consise and as
infrequent as possible for you.

Will rebase my patch set to the latest release this week and resend them for review.
Masahiro, what version of GCC is prefered (if any) for the next release  of U-Boot.
I am currently using the GCC-4.4 toolchain from Cobham Gaisler.

Regards,
  Francois

Any semi-modern toolchain is fine with me.  Can you point me at the 4.4
toolchain and I'll put sparc back into my build-test cycle?  Thanks!

I have been using this compiler up to now:
  http://www.gaisler.com/anonftp/bcc/bin/linux/sparc-elf-4.4.2-1.0.44.tar.bz2

Daniel is that the one you have been refering to?

  Francois

Then please send me your SSH public key, so I can enable write access

I am not familiar with SPARC architecture at all, but
I use kernel.org one for build test.

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/

x86_64-gcc-4.9.0-nolibc_sparc-linux.tar.xz


Please note, I have not tested it on any real sparc boards.

I'm on parental leave until January, but I'll do my best.
