Puzzled nand and u-boot

Can somebody explain the use of nand and the need for u-boot when flashing the Firefly when using the RK Flashtools in windows. Also  Android refers to internal storage as nand.  Have seen it named as flash, but have not found how to build with this (flash) yet, and it is causing some errors if parameters are changed, then one loses access to internal storage and some kernel functions.

Thanks to you both.  I have the problem with the use of "u-boot" being used when it is not used in flashing the program.  i.e. if you unpack an Img.img you will get the normal group of files. which do not include a "u-boot" file.  They will include a loader.bn file for bootloader, and the parameter file is a parameter file.  Where I have ran into problems is the labeling of the parameter file as a "u-boot" 1G data file, when trying to load a parameter for increased internal storage or changing to a larger system file.   Have been able to copy and paste new parameter file into the u-boot 1Gdata parameter file, but this can get confusing.  I have one question is there actually any use what so ever for a "u-boot" and the RK3288 except for a Nand, which I doubt we will ever see used with this chip.  This is my frustration is for have been working with u-boot, kernel 3.10, android, and nand on the RK3188 for months and there seems to be NO solution so far, I believe Astralix is still working on this.  Has any one actually tried u-boot on the RK3288 to see if it actually (RK3288 and internal nand) works.

can we possibly redo the 2.17 rktool to use "parameter" instead of "u-boot 1G data".
