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.
