After checking the datasheet, I don't understand how we can change the geometry of this SDRAM controler while running from SDRAM : each time we increase the colum number, the address are modified thus we can't execute any more u-boot's code as it's no more where we are expecting it.
You cannot - that's obvious. You must not meddle with the SDRAM controler at all while running from this bank of memory. This code should be running from flash (or SRAM, or wherever you boot from).
Best regards,
