[U-Boot-Users] Clarification regarding the Internal Flash Identification Code.

Hi All In the file "include/flash.h" some # defines are there e.g for Intel StrataFlash 28F320J5 three Macros (hash define values) are there:
#define INTEL_MANUFACT 0x00890089 /*INTEL manuf. ID in D23..D16, D7..D0 */ #define INTEL_ID_28F320J5 0x00140014 /* 32M = 128K x 32 */ #define FLASH_28F320J5 0x0085 /* Intel 28F320J5 ( 4M = 128K x 32 ) */
Since I am using Intel StrataFlash 28F256J3, I have to define the three required macros accordingly:
#define INTEL_MANUFACT 0x00890089 /*INTEL Manufacturer. ID */ #define INTEL_ID_28F256J3 0x001D001D /*Device ID*/
#define FLASH_28F256J3 /*Internal Flash Identification Code*/
I got the Device Id value from the Intel Site but I didn't found any thing like Internal Flash Identification Code. Is this value is to be supplied by the vendor if not then what value should I have to assign to the Macro FLASH_28F256J3.

As the name "Internal FLASH identification codes" suggests this is a code that is _internal_ to U-Boot so you will not find it mentioned in any vendor documentation (at least not before they are sterting to manufacture "U-Boot flash chips" :-)
Just chose the next unused entry, but keep in mind that odd numbers are used only for "bottom boot sector" types!
