how can i use 4K-page nand (MT29F8G08ABACAWP) in P1020/P1011

[hyoungkikim]

hello experts

CPU is P1020/P1011  and a borad was  used a few years without problems

kernel and u-boot are from SDK 1.8

this time  i have to install 1GB nand  so i  plan to  use  MT29F8G08A instead of MT29F1G08 which  was installed on the board

i read a user guide ann it said  it can interface a small and a large nand , and the large nand is 2K-page device

how could i interface 4K-page nand with FCM   ?

thank you for your advices

In u-boot source code include/configs/p1_p2_rdb_pc.h, please configure ELBC  BR and OR as the following.

#define CONFIG_SYS_NAND_BR_PRELIM (BR_PHYS_ADDR(CONFIG_SYS_NAND_BASE_PHYS) \
        | (2<<BR_DECC_SHIFT)    /* Use HW ECC */ \
        | BR_PS_8       /* Port Size = 8 bit */ \
        | BR_MS_FCM     /* MSEL = FCM */ \
        | BR_V) /* valid */
#if defined(CONFIG_P1020RDB_PD)
#define CONFIG_SYS_NAND_OR_PRELIM       (0xFFFC0000  /* length 256K */ \
