Hello,
I want to chose the best aproach to achive something like this: There is a u-boot without SPL and it is copied by bootrom to SDRAM. In first phase (while running *_f functions) I need to read some configuration data from SPI NOR, and it must be done before DDR config. I have SPI NOR with enabled MTD support on SPI. Problem is that MTD uses bss wich is not avalaible yet. My solutions: * Change linker script to divide bss and rel.dyn sections and clean bss by myself. Disadventage is that it will enlarge my binary, but it migh be acceptable. * Write code that do not use SPI/MTD frameworks to read configuration data (data will be on raw so MTD is not needed). For sure - at least at the moment - I wan't to avoid using SPL and config compiled into binary. Maybe there is another way that I can achive that?
