ADI_EBIU_SDRAM_BANK_SIZE

This enumeration specifies the SDRAM external bank size. This enumera-
tion corresponds to the
ADI_EBIU_SDRAM_BANK_16MB
ADI_EBIU_SDRAM_BANK_32MB
ADI_EBIU_SDRAM_BANK_64MB
ADI_EBIU_SDRAM_BANK_128MB
The default value is specified by the following macro:
#define ADI_EBIU_SDRAM_BANK_SIZE_DEFAULT
ADI_EBIU_SDRAM_BANK_32MB

ADI_EBIU_SDRAM_BANK_COL_WIDTH

This enumeration specifies the SDRAM external bank column address
width and corresponds to the
ADI_EBIU_SDRAM_BANK_COL_8BIT
ADI_EBIU_SDRAM_BANK_COL_9BIT
ADI_EBIU_SDRAM_BANK_COL_10BIT
ADI_EBIU_SDRAM_BANK_COL_11BIT
The default value is specified by the following macro:
#define ADI_EBIU_SDRAM_BANK_COL_WIDTH_DEFAULT
ADI_EBIU_SDRAM_BANK_COL_9BIT

ADI_EBIU_SDRAM_MODULE_TYPE

This enumeration specifies an SDRAM module type when the command
