Hello again Sorry for slipping the u-boot list e-mail address
i understand the benefit of relocating u-boot to the end of DRAM but in systems where boot time is critical this redundant copy is undesirable. anyway i understand there is no official way of avoiding it. One more question i have is regarding the SPL Framework. i read all the documentation i could find about the SPL but i don't think i fully understand the usage of this framework. since i noticed several SPL Macros around the relocation code i suspected it has something to do with relocation or u-boot running as secondary boot program i would appreciate a short explanation when CONFIG_SPL or CONFIG_NAND_SPL should be set ?
