[U-Boot-Users] which board shall I begin with?

I'm quite new to U-Boot. I'm focus on such a board:

CPU: Intel XScale GDPXA255A0C400 Flash: Intel StrataFlash 16MB x 2 SDRAM: Samsung K4S5616320 32MB x 2

I'm confused with the board names within the folder "/board". Which board shall I begin with? Thanks.
