Hi Marcel,
The actual line which does have impact is `CONFIG_DFU_MMC=y`.
Vybrid is using raw NAND and not eMMC.
Not sure I understand the reason of adding "# ... is not set" lines in this defconfig. Could you please explain?
That just explicitly disables stuff.
Regards, Igor

Disable more obscure options to save another 26 KB
That's the short explanation.
The long one involves understanding that the Vybrid currently runs U- Boot in its SRAM (rather than DDR) which is limited in size.
in preparation of the upcoming driver model migration.
