2013-08-30mtd: nand: pxa3xx: Use 'length override' in ONFI paramater page readEzequiel Garcia
The ONFI command 'parameter page read' needs a non-standard length. Therefore, we enable the 'length override' field in NDCB0 and set a non-zero 'length count' in NDCB3. Additionally, the 'spare enable' bit must be disabled for any command that sets a non-zero 'length count' in NDCB3.

2013-08-30mtd: nand: pxa3xx: Introduce 'marvell,armada370-nand' compatible stringEzequiel Garcia
This driver supports NFCv1 (as found in PXA SoC) and NFCv2 (as found in Armada 370/XP SoC). As both controller has a few differences, a way of distinguishing between the two is needed. This commit introduces a new compatible string 'marvell,armada370-nand' and assigns a compatible data of type enum pxa3xx_nand_variant to allow such distinction.

2013-08-30mtd: gpmi: set the BCH's geometry with the ecc infoHuang Shijie
If the nand chip provides us the ECC info, we can use it firstly. The set_geometry_by_ecc_info() will use the ECC info, and calculate the parameters we need. Rename the old code to legacy_set_geometry() which will takes effect when there is no ECC info from the nand chip or we fails in the ECC info case.

2013-08-30mtd: get the ECC info from the Extended Parameter PageHuang Shijie
Since the ONFI 2.1, the onfi spec adds the Extended Parameter Page to store the ECC info. The onfi spec tells us that if the nand chip's recommended ECC codeword size is not 512 bytes, then the @ecc_bits is 0xff. The host _SHOULD_ then read the Extended ECC information that is part of the extended parameter page to retrieve the ECC requirements for this device. This patch implement the reading of the Extended Parameter Page, and parses the sections for ECC type, and get the ECC info from the ECC section. Tested this patch with Micron MT29F64G08CBABAWP.

2013-08-30mtd: add datasheet's ECC information to nand_chip{}Huang Shijie
1.) Why add the ECC information to the nand_chip{} ? Each nand chip has its requirement for the ECC correctability, such as "4bit ECC for each 512Byte" or "40bit ECC for each 1024Byte". This ECC info is very important to the nand controller, such as gpmi. Take the Micron MT29F64G08CBABA for example, its geometry is 8KiB page size, 744 bytes oob size and it requires 40bit ECC per 1KiB. If we do not provide the ECC info to the gpmi nand driver, it has to calculate the ECC correctability itself. The gpmi driver will gets the 56bit ECC for per 1KiB which is beyond its BCH's 40bit ecc capibility. The gpmi will quits in this case. But in actually, the gpmi can supports this nand chip if it can get the right ECC info. 2.) about the new fields. The @ecc_strength_ds stands for the ecc bits needed within the @ecc_step_ds. The two fields should be set from the nand chip's datasheets. For example: "4bit ECC for each 512Byte" could be: @ecc_strength_ds = 4, @ecc_step_ds = 512. "40bit ECC for each 1024Byte" could be: @ecc_strength_ds = 40, @ecc_step_ds = 1024. 3.) Why do not re-use the @strength and @size in the nand_ecc_ctrl{}? The @strength and @size in nand_ecc_ctrl{} is used by the nand controller driver, while the @ecc_strength_ds and @ecc_step_ds are get from the datasheet.
