/**
 * cvmx_ndf_bt_pg_info
 *
 * Notes:
 * NDF_BT_PG_INFO provides page size and number of column plus row address cycles information. SW writes to this CSR
 * during boot from Nand Flash. Additionally SW also writes the multiplier value for timing parameters. This value is
 * used during boot, in the SET_TM_PARAM command. This information is used only by the boot load state machine and is
 * otherwise a don't care, once boot is disabled. Also, boot dma's do not use this value.
 *
 * Bytes per Nand Flash page = 2 ** (SIZE + 1) times 256 bytes.
 * 512, 1k, 2k, 4k, 8k, 16k, 32k and 64k are legal bytes per page values
 *
 * Legal values for ADR_CYC field are 3 through 8. SW CSR writes with a value less than 3 will write a 3 to this
 * field, and a SW CSR write with a value greater than 8, will write an 8 to this field.
 *
 * Like all NDF_... registers, 64-bit operations must be used to access this register

/**
 * cvmx_ndf_drbell
 *
 * 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.
 *

/**
 * cvmx_ndf_misc
 *
 * 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.
 *
 * Like all NDF_... registers, 64-bit operations must be used to access this register
