How do I modify SLC NAND flash parameters for u-boot ?

When I say "nand parameters", I meant things like " how many pages in a block, how many blocks and how big is each page," not timing.

Is it per NAND controller implementation specific or is it more generic across u-boot?

These parameters are dictated by the physical hardware. If you mean how do you tell U-Boot about how the hardare is laid out, typically it is automatically detected, but some things like bus width and page size need to be specified for certain drivers. The way to do this is specific to the controller driver, but typically involves defining certain symbols in the board config header.
