But how can you determine the number of Column/Row address bits and the number of internal SDRAM banks?
Just try it out :-)
See for example function initdram() in "board/tqm8xx/tqm8xx.c" - here we assume to have a maximum of 2 banks of SRAM, and try out both banks both with 8, 9 and 10 columns each.
Of course we assume that you know which chips and how many banks are theoretically possible on your board.
