How to support MXIC nand flash?

[9crkzhou]

I'm using MX283

L2.3.35

default is not supporting MXIC

my new chip is MX30LF1G08AA  128M 1024blocks  128k per block  64pages per block

to support MFGTOOL

I need a updater.sb file

then I built the LTIB and get a new updater_ivt.sb and updater.sb

mainly modiffied those place:

driver/mtd/nand/nand_ids.c

add

{"NAND 238MiB 3,3V 8-bit", 0xF0, 0,128,0,LP_OPTIONS},

add

{0xc2, "Macronix"},

driver/mtd/nand/nand_device_info.c

add

  {

    .end_of_table             = false,

    .manufacturer_code        = 0xc2,

    .device_code              = 0xf1,

    .cell_technology          = NAND_DEVICE_CELL_TECH_SLC,

    .chip_size_in_bytes       = 128LL*SZ_1M,

    .block_size_in_pages      = 64,

    .page_total_size_in_bytes = 2*SZ_1K,

    .ecc_strength_in_bits     = 4,

    .ecc_size_in_bytes        = 512,

    .data_setup_in_ns         = 30,

    .data_hold_in_ns          = 20,

    .address_setup_in_ns      = 0,

    .gpmi_sample_delay_in_ns  = 6,

    .tREA_in_ns               = -1,

    .tRLOH_in_ns              = -1,

    .tRHOH_in_ns              = -1,

    "Macronix",

    },

it not work!

how to deal with this?

fix already.

only need to modify nand_ids.c and nand_device_info.c

If possibly , try using mainline U-Boot 2014.01 and mainline Linux at least 3.10.xx . They have myriad of fixes .
