"NOTE: PG2.x devices support booting from SD cards larger than 4 GB in size."

My question:

1. Can you tell me the difference between PG2.X  and PG1.X

2. if PG2.X dm8168, sd card capacity should > 4GB, yes?  if PG1.X dm8168, sd card capacity should <= 4GB, yes?

    No, in PG2.x DM8168, SD card capacity can be < 4GB. Check the below info:

    http://processors.wiki.ti.com/index.php/TI81XX_PSP_U-Boot#U-Boot_SD_.28Secured_Digital_card.29_Support

    Empty SD card (at least 256MB, preferably 4GB SDHC)

    Now I know "DEVICE REVISION x == PGx" . whose abbreviation is PG? It is so strange.
