Hi,

I am new to U-Boot. [Yes... I have been reading the documentation, albeit slowly. There is much to learn.]

I need to modify include/flash.h to support Spansion S29JL064H flash memory

    http://www.spansion.com/products/S29JL064H.html

A search through previous postings to this list did not reveal appropriate values for

    * Device ID

    * Internal FLASH identification code

[Do I need one or the other or both?]

This chip is CFI compliant. CFI stands for 'Common Flash Interface', and means that software can learn the chip's topology via a standard query method. In short, you shouldn't need to do anything with flash.h, all you need to do is specify in your board's /include/configs/*.h file that your board uses CFI. Lots of other boards use it, so look through the source to figure out the exact syntax.
