Hello Jakub,
So, does this contribution made me passing patch requirement?
Yes. But note that it is only a prerequisite, the formal SOCIS
student selection process starts only after the application deadline.
Don't forget to submit your application [1] and please use our
application template [2].

I've just sent my application. :) I'm looking forward for some
feedback on it.
* qemu - totally no luck. I've tried passing u-boot binary as -bios
parameter (which seems to be expected, as default "PROM_FILENAME"
in https://github.com/qemu/qemu/blob/master/hw/sparc/leon3.c is
"u-boot.bin"). There was no console output and no signs of life.
I have tested QEMU 1.5.0 with the following command line
qemu-system-sparc -M leon3_generic -cpu LEON3 -nographic
I have used exactly the same command line arguments and u-boot source
from Gaisler FTP (slightly modified, as vanilla sources did not compile
due to some trivial errors).
QEMU loads u-boot.bin and it apparently runs some code (it is busy),
but there is still no output. I believe that the problem might be as
simple as configuring the I/O devices where the u-boot compiled for
GRSIM/TSIM expects them, but sure the QEMU documentation is rather
poor on this.
I think that there's incompatibility between configurations emulated
by TSIM and qemu. Probably qemu emulated system is modeled after some
FPGA board. The lack of output can be as simple as wrong UART
configured
for console. I'll inspect qemu source code today and try to make it
working.
This indeed looks reasonable and it is also reasonably cheap. But I
still suggest to wait for the reply from ESA whether we get access to
the full version of TSIM. We can always decide to buy the hardware
later on.
I'm looking forward for news about that. :)
Jakub
