1 * Freescale General-Purpose Media Interface (GPMI)
3 The GPMI nand controller provides an interface to control the
7 - compatible : should be "fsl,<chip>-gpmi-nand"
8 - reg : should contain registers location and length for gpmi and bch.
9 - reg-names: Should contain the reg names "gpmi-nand" and "bch"
10 - interrupts : BCH interrupt number.
11 - interrupt-names : Should be "bch".
12 - dmas: DMA specifier, consisting of a phandle to DMA controller node
13 and GPMI DMA channel ID.
14 Refer to dma.txt and fsl-mxs-dma.txt for details.
15 - dma-names: Must be "rx-tx".
18 - nand-on-flash-bbt: boolean to enable on flash bbt option if not
20 - fsl,use-minimum-ecc: Protect this NAND flash with the minimum ECC
21 strength required. The required ECC strength is
22 automatically discoverable for some flash
23 (e.g., according to the ONFI standard).
24 However, note that if this strength is not
25 discoverable or this property is not enabled,
26 the software may chooses an implementation-defined
28 - fsl,no-blockmark-swap: Don't swap the bad block marker from the OOB
29 area with the byte in the data area but rely on the
30 flash based BBT for identifying bad blocks.
31 NOTE: this is only valid in conjunction with
33 WARNING: on i.MX28 blockmark swapping cannot be
34 disabled for the BootROM in the FCB. Thus,
35 partitions written from Linux with this feature
36 turned on may not be accessible by the BootROM
39 The device tree may optionally contain sub-nodes describing partitions of the
40 address space. See partition.txt for more detail.
