Hi
i need to configure u-boot-2012.10, for my custom board, that is very close
to at91rm9200ek, except that i have 32MB NOR flash, and 32MB SDRAM.
what i fail to understand is the following config parameters:


#define CONFIG_SYS_PIOC_ASR_VAL
#define CONFIG_SYS_PIOC_BSR_VAL
//#define CONFIG_SYS_PIOC_PDR_VAL
#define CONFIG_SYS_PIOC_PDR_VAL
#define CONFIG_SYS_EBI_CSA_VAL
#define CONFIG_SYS_SDRC_CR_VAL
#define CONFIG_SYS_SDRAM                 CONFIG_SYS_SDRAM_BASE /* address
of the SDRAM */
#define CONFIG_SYS_SDRAM1                (CONFIG_SYS_SDRAM_BASE+0x80)
#define CONFIG_SYS_SDRAM_VAL
#define CONFIG_SYS_SDRC_MR_VAL
#define CONFIG_SYS_SDRC_MR_VAL1
#define CONFIG_SYS_SDRC_MR_VAL2
#define CONFIG_SYS_SDRC_MR_VAL3
#define CONFIG_SYS_SDRC_TR_VAL

Any help is badly required.

Thanks
Arivendu
