I created a new source code tree for only one motherboard, ASUS, MEW_AM. There is no build/bootblock folder and CONFIG_TINY_BOOTBLOCK and CONFIG_BOOTBLOCK_SIMPLE are not set. What is the difference between tiny and big boot block? My second question is that the code of bootblock is copied to romstage too. I mean we have a duplicate code in two different components. Is that right?

In big boot block mode, romstage (and thus ram init) is part of the boot block. In tiny boot block mode, romstage is an extra file in CBFS.

That might be a mistake. Where did you see that?

I think i made a mistake. In big boot block, bootblock code is written once for coreboot.pre and the same is for tiny boot block. My source of confusion was the inclusion of the bootblock code in crt0. Regards
