afaict the leftover budget is unused for both of those, so is available for
re-assigning.

the whole budget is used in bug #1026, like #1025 there are enough subtasks
that we are constrained by the budget and will have to pick and choose what to
do. the full list of tasks isn't established for #1026 yet since it'll likely
be partially leftovers from #1025 and I haven't done the subtask budget
estimation yet.

as mentioned on IRC, I already finished all non-binutils work for bug #1035 and
I'm happy with the budget. the binutils budget under #1035 is currently set to
EUR 1000 and ghostmansd seems happy with that, since the work should be pretty
easy to do. ghostmansd left the budget assignment for the rest of #1035 up to
the rest of us:

ok, I missed that on bug #1047 you already did most the work and the extra
budget would be needed for getting whoever works on it up-to-speed.

As mentioned on IRC, I don't think we should assign more budget to
Vectorised-Immediates since I think it should be lower priority than #1025 and
most other tasks, if we run out of budget for Vectorised-Immediates then I
think we should do what fits in the current budget and put off the rest for
another grant.

therefore, I think we should take the leftover budget from bug #737 and bug
#1035 and assign it like so:

we have EUR 6500 to distribute:
* bug #1047 gets additional EUR 1000 
  2500 for lkcl and 1500 for whoever finishes it off
  the additional money is for the learning curve and because there's not
  much left after paying lkcl.
* bug #1025 gets additional EUR 4500
  it could use a lot more than that...iirc the full task list 
  sums to well in excess of 20k, somewhere around 30k last I checked
* bug #1146 gets EUR 1000 
  assigned through bug #1037 increasing it to EUR 7000
  I think it's highly beneficial to have a decent amount of working ram
  without needing to wait on ddr3 getting figured out.
  additionally, making it work with a RPi or other SBC with a SPI interface
  is useful because they're much more widely available than HyperRAM and
  have much more ram, enough that we could run compilers and stuff.
  I estimate that EUR 1000 is just about enough to get the wishbone to
  SPI slave translator and write the simple ram emulator program which
  will use SPI through Linux's drivers.
