| 346 | * preamble that performs an IOBARRIER in the extremely unlikely event | |
| 347 | * that the driver interrupts itself between a writew to the chip an | |
| 348 | * the IOBARRIER that follows *and* the cache is large enough that the | |
| 349 | * first off-chip access while handing the interrupt is to the SMC | |
| 350 | * chip. Other devices in the same address space as the SMC chip must | |
| 351 | * be aware of the potential for trouble and perform a similar | |
| 352 | * IOBARRIER on entry to their ISR. | |
