[U-Boot] How to do serial pages reading in K9f1208u0b-pcb nand chip from SAMSUNG?

[yihect]

 Is someone using k9f1208u0b chip for booting u-boot??
The datasheet says that there are three ways for reading:
1, random read. Read any location of 528Bytes in a row. (Read1 and Read 2);
2, serial page read. (my question)
3, sequential row read. Read rows in a block one by one. 
 
But there is not many description on serial read in the datasheet. HOW to do serial pages reading when copying u-boot content from the nand chip into ram?
