* 512, 1k, 2k, 4k, 8k, 16k, 32k and 64k are legal bytes per page values
*

* Notes:
* SW csr writes will increment CNT by the signed 8 bit value being written. SW csr reads return the current CNT value.
* HW will also modify the value of the CNT field. Everytime HW executes a BUS_ACQ[15:0] command, to arbitrate and win the
* flash bus, it decrements the CNT field by 1. If the CNT field is already 0 or negative, HW command execution unit will
* stall when it fetches the new BUS_ACQ[15:0] command, from the command fifo. Only when the SW writes to this CSR with a
* non-zero data value, can the execution unit come out of the stalled condition, and resume execution.
*
* The intended use of this doorbell CSR is to control execution of the Nand Flash commands. The NDF execution unit
* has to arbitrate for the flash bus, before it can enable a Nand Flash device connected to the Octeon chip, by
* asserting the device's chip enable. Therefore SW should first load the command fifo, with a full sequence of
* commands to perform a Nand Flash device task. This command sequence will start with a bus acquire command and
* the last command in the sequence will be a bus release command. The execution unit will start execution of
* the sequence only if the [CNT] field is non-zero when it fetches the bus acquire command, which is the first
* command in this sequence. SW can also, load multiple such sequences, each starting with a chip enable command
* and ending with a chip disable command, and then write a non-zero data value to this csr to increment the
* CNT field by the number of the command sequences, loaded to the command fifo.

*
* Notes:
* NBR_HWM this field specifies the high water mark for the NCB outbound load/store commands receive fifo.
* the fifo size is 16 entries.
*
* WAIT_CNT this field allows glitch filtering of the WAIT_n input to octeon, from Flash Memory. The count
* represents number of eclk cycles.
*
* FR_BYT this field specifies \# of unfilled bytes in the command fifo. Bytes become unfilled as commands
* complete execution and exit. (fifo is 256 bytes when BT_DIS=0, and 1536 bytes when BT_DIS=1)
*
* RD_DONE this W1C bit is set to 1 by HW when it reads the last 8 bytes out of the command fifo,
* in response to RD_CMD bit being set to 1 by SW.
*
* RD_VAL this read only bit is set to 1 by HW when it reads next 8 bytes from command fifo in response
* to RD_CMD bit being set to 1. A SW read of NDF_CMD csr clears this bit to 0.
*
* RD_CMD this R/W bit starts read out from the command fifo, 8 bytes at a time. SW should first read the
* RD_VAL bit in this csr to see if next 8 bytes from the command fifo are available in the
* NDF_CMD csr. All command fifo reads start and end on an 8 byte boundary. A RD_CMD in the
* middle of command execution will cause the execution to freeze until RD_DONE is set to 1. RD_CMD
* bit will be cleared on any NDF_CMD csr write by SW.
*
* BT_DMA this indicates to the NAND flash boot control state machine that boot dma read can begin.
* SW should set this bit to 1 after SW has loaded the command fifo. HW sets the bit to 0
* when boot dma command execution is complete. If chip enable 0 is not nand flash, this bit is
* permanently 1'b0 with SW writes ignored. Whenever BT_DIS=1, this bit will be 0.
*
* BT_DIS this R/W bit indicates to NAND flash boot control state machine that boot operation has ended.
* whenever this bit changes from 0 to a 1, the command fifo is emptied as a side effect. This bit must
* never be set when booting from nand flash and region zero is enabled.
*
* EX_DIS When 1, command execution stops after completing execution of all commands currently in the command
* fifo. Once command execution has stopped, and then new commands are loaded into the command fifo, execution
* will not resume as long as this bit is 1. When this bit is 0, command execution will resume if command fifo
* is not empty. EX_DIS should be set to 1, during boot i.e. when BT_DIS = 0.
*
* RST_FF reset command fifo to make it empty, any command inflight is not aborted before reseting
* the fifo. The fifo comes up empty at the end of power on reset.
