pokeAt with SyncReadMem

[immesys]

I can't seem to use pokeAt with SyncReadMem. I get this:

[error]  found   : chisel3.core.SyncReadMem[chisel3.core.UInt]
[error]  required: chisel3.Mem[?]
[error]     (which expands to)  chisel3.core.Mem[?]
[error]   pokeAt(tl.mem, 1, 15)

Is there a way around this? I can switch my memory to a normal Mem for testing, but that's not ideal.

I believe this is fixed with PR #274
