mem_ap_write() function

The MEM-AP to access.

The data buffer to write. No particular alignment is assumed.

Which access size to use, in bytes. 1, 2, or 4. If large data extension is available also accepts sizes 8, 16, 32.

The number of writes to do (in size units, not bytes).

Address to be written; it must be writable by the currently selected MEM-AP.

Whether the target address should be increased for each write or not. This should normally be true, except when writing to e.g. a FIFO.

Queue an AP register read.

Queue an AP register write.

Asynchronous (queued) read of a word from memory or a system register.

Asynchronous (queued) write of a word to memory or a system register.

Synchronous read of a word from memory or a system register. As a side effect, this flushes any queued transactions.

Synchronous write of a word to memory or a system register. As a side effect, this flushes any queued transactions.

Initialize a DAP. This sets up the power domains, prepares the DP for further use, and arranges to use AP #0 for all AP operations until dap_ap-select() changes that policy.

Queue transactions setting up transfer parameters for the currently selected MEM-AP. Subsequent transfers using registers like MEM_AP_REG_DRW or MEM_AP_REG_BD2 initiate data reads or writes using memory or peripheral addresses. If the CSW is configured for it, the TAR may be automatically incremented after each transfer.

Queue transactions setting up transfer parameters for the currently selected MEM-AP. If transfer size or packing has not been probed, run the queue, read back CSW and check if the requested transfer mode is supported.

Wrapper around struct rtp_ops::ap_header.

Wrapper around struct rtp_ops::mem_ap_header. Input parameter @a retval is propagated.

Queue transactions setting up transfer parameters for the currently selected MEM-AP. If transfer size or packing has not been probed, run the queue, read back CSW and check if the requested transfer mode is supported. If packing is not supported fallback and prepare CSW for unpacked transfer.

Synchronous read of a block of memory, using a specific access size.

Helper to read CoreSight component's registers, either on the bus behind a MEM-AP or directly in the AP.

Read the CoreSight registers needed during ROM Table Parsing (RTP).
