It should be set automatically.

Carl-Daniel clarified on IRC that the "atomic" cycle flag will always be 0
at the stage they are printed. Sorry for the confusion!

I recommend adding a debug print to ich9_run_opcode() to see what the
"atomic" flag ends up being:

Index: ichspi.c
--- ichspi.c    (revision 1483)
+++ ichspi.c    (working copy)
@@ -908,6 +908,7 @@
           This means the timeout must be sufficient for chip erase
           of slow high-capacity chips.
+       msg_pdbg("opcode: 0x%02x, spi_type: %u, atomic: %u\n", op.opcode,
op.spi_type, op.atomic);
        switch (op.atomic) {
        case 2:
                /* Select second preop. */

Then run "flashrom -V -p internal:this_is_not_a_laptop -r foo.bin" and make
sure that the sector erase opcode (0x20) and byte program opcode (0x02)
show either "1" or "2" for op.atomic.

This will help us to prove whether or not this is the problem you are

Okay. I do not think Flashrom is confused about the flash part, then.
