[U-Boot-Users] SDRAM init, and Chip Selects

How do you initialize the SDRAM controller of the 405GPr?

In board_init_f function, there's a call to an initdram function. In this
function, you can choose between explicitely initializing the SDRAM
controller from fixed values or read SDRAM information (from an I2C EEprom
or another device depending on your board) and calculate the values (as
that was done for the Walnut board for example).

Hope this helps,
