When running the board with the DM_SERIAL driver, the board ran out of memory in SPL when initialising the DM serial driver. Thus this required an increase in the pre-allocated SRAM memory. I did increase it to 0x800, and it now works graciously. It could probably be set lower, but I do not see any reason not to use the available SRAM at this point. Also adds stdout-path to the 'chosen' node in the device tree. Signed-off-by: Ole P.
