/*
* During normal bootup, small reads may be required.
* Rather than issue an HIF Read and then wait as the Target
* adds successive bytes to the FIFO, we wait here until
* we know that response data is available.
*
* This allows us to cleanly timeout on an unexpected
* Target failure rather than risk problems at the HIF level.
* In particular, this avoids SDIO timeouts and possibly garbage
* data on some host controllers. And on an interconnect
* such as Compact Flash (as well as some SDIO masters) which
* does not provide any indication on data timeout, it avoids
* a potential hang or garbage response.
*
* Synchronization is more difficult for reads larger than the
* size of the MBOX FIFO (128B), because the Target is unable
* to push the 129th byte of data until AFTER the Host posts an
* HIF Read and removes some FIFO data. So for large reads the
* Host proceeds to post an HIF Read BEFORE all the data is
* actually available to read. Fortunately, large BMI reads do
* not occur in practice -- they're supported for debug/development.
*
* So Host/Target BMI synchronization is divided into these cases:
* CASE 1: length < 4
* Should not happen
*
* CASE 2: 4 <= length <= 128
* Wait for first 4 bytes to be in FIFO
* If CONSERVATIVE_BMI_READ is enabled, also wait for
* a BMI command credit, which indicates that the ENTIRE
* response is available in the the FIFO
*
* CASE 3: length > 128
* Wait for the first 4 bytes to be in FIFO
*
* For most uses, a small timeout should be sufficient and we will
* usually see a response quickly; but there may be some unusual
* (debug) cases of BMI_EXECUTE where we want an larger timeout.
* For now, we use an unbounded busy loop while waiting for
* BMI_EXECUTE.
*
* If BMI_EXECUTE ever needs to support longer-latency execution,
* especially in production, this code needs to be enhanced to sleep
* and yield. Also note that BMI_COMMUNICATION_TIMEOUT is currently
* a function of Host processor speed.

* During normal bootup, small reads may be required.
* Rather than issue an HIF Read and then wait as the Target
* adds successive bytes to the FIFO, we wait here until
* we know that response data is available.
*
* This allows us to cleanly timeout on an unexpected
* Target failure rather than risk problems at the HIF level.
* In particular, this avoids SDIO timeouts and possibly garbage
* data on some host controllers. And on an interconnect
* such as Compact Flash (as well as some SDIO masters) which
* does not provide any indication on data timeout, it avoids
* a potential hang or garbage response.
*
* Synchronization is more difficult for reads larger than the
* size of the MBOX FIFO (128B), because the Target is unable
* to push the 129th byte of data until AFTER the Host posts an
* HIF Read and removes some FIFO data. So for large reads the
* Host proceeds to post an HIF Read BEFORE all the data is
* actually available to read. Fortunately, large BMI reads do
* not occur in practice -- they're supported for debug/development.
*
* So Host/Target BMI synchronization is divided into these cases:
* CASE 1: length < 4
* Should not happen
*
* CASE 2: 4 <= length <= 128
* Wait for first 4 bytes to be in FIFO
* If CONSERVATIVE_BMI_READ is enabled, also wait for
* a BMI command credit, which indicates that the ENTIRE
* response is available in the the FIFO
*
* CASE 3: length > 128
* Wait for the first 4 bytes to be in FIFO
*
* For most uses, a small timeout should be sufficient and we will
* usually see a response quickly; but there may be some unusual
* (debug) cases of BMI_EXECUTE where we want an larger timeout.
* For now, we use an unbounded busy loop while waiting for
* BMI_EXECUTE.
*
* If BMI_EXECUTE ever needs to support longer-latency execution,
* especially in production, this code needs to be enhanced to sleep
* and yield. Also note that BMI_COMMUNICATION_TIMEOUT is currently
* a function of Host processor speed.
