30  * to examine and modify state.  The Host has an opportunity to use
31  * BMI only once during bootup.  Once the Host issues a BMI_DONE
32  * command, this opportunity ends.
34  * The Host writes BMI requests to mailbox0, and reads BMI responses
35  * from mailbox0.   BMI requests all begin with a command
37  * command-specific data.
40  * The Host can only issue a command once the Target gives it a
41  * "BMI Command Credit", using ATH6KL Counter #4.  As soon as the
42  * Target has completed a command, it issues another BMI Command
43  * Credit (so the Host can issue the next command).
45  * BMI handles all required Target-side cache flushing.
54  * Semantics: Host is done using BMI
56  *    u32 command (BMI_DONE)
62  * Semantics: Host reads ATH6KL memory
64  *    u32 command (BMI_READ_MEMORY)
73  * Semantics: Host writes ATH6KL memory
75  *    u32 command (BMI_WRITE_MEMORY)
86  *    u32 command (BMI_EXECUTE)
97  *    u32 command (BMI_SET_APP_START)
104  * Semantics: Read a 32-bit Target SOC register.

114  * Semantics: Write a 32-bit Target SOC register.
116  *    u32 command (BMI_WRITE_REGISTER)
126  * Semantics: Fetch the 4-byte Target information

189  * Semantics: Begin an LZ-compressed stream of input
194  * command should be followed by a series of 1 or more
196  *    u32 command (BMI_LZ_STREAM_START)
203  * Semantics: Host writes ATH6KL memory with LZ-compressed
204  * data which is uncompressed by the Target.  This command
