* 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

* Bootloader Messaging Interface (BMI)
*
* BMI is a very simple messaging interface used during initialization
* to read memory, write memory, execute code, and to define an
* application entry PC.
*
* It is used to download an application to ATH6KL, to provide
* patches to code that is already resident on ATH6KL, and generally
* to examine and modify state. The Host has an opportunity to use
* BMI only once during bootup. Once the Host issues a BMI_DONE
* command, this opportunity ends.
*
* The Host writes BMI requests to mailbox0, and reads BMI responses
* from mailbox0. BMI requests all begin with a command
* (see below for specific commands), and are followed by
* command-specific data.
*
* Flow control:
* The Host can only issue a command once the Target gives it a
* "BMI Command Credit", using ATH6KL Counter #4. As soon as the
* Target has completed a command, it issues another BMI Command
* Credit (so the Host can issue the next command).
*
* BMI handles all required Target-side cache flushing.
