Check Expect files

Some expect files that should be double checked:
- examples/wishbone/expects/test_sram_incrementing_16_0_3.bi.expect (why is the burst data unknown?)
- examples/wishbone/expects/test_sram_incrementing_16_12_3.bi.expect (same)
- examples/wishbone/expects/test_sram_incrementing_16_4_3.bi.expect
- examples/wishbone/expects/test_sram_incrementing_16_8_3.bi.expect
- examples/wishbone/expects/test_sram_incrementing_2_0_3.bi.expect
- examples/wishbone/expects/test_sram_incrementing_2_8_3.bi.expect

Start by reading the six expect files under examples/wishbone/expects and trace the corresponding test_sram_incrementing examples to understand the burst-data cases. Determine why burst data is unknown in the noted files, then verify that the expect files reflect the correct behavior or document the confirmed result.
