Some archs/boards specify their own default by pre-defining the config which causes the Kconfig system to mix up the order of the configs in the defconfigs... This will cause merge pain if allowed to proliferate. Remove the configs that behave this way from the archs. A few configs still remain, but that is because they only exist as defaults and do not have a proper Kconfig entry. Those appear to be: SPIFLASH DISPLAY_BOARDINFO Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> [trini: rastaban, am43xx_evm_usbhost_boot, am43xx_evm_ethboot updates, drop DM_USB from MSI_Primo81 as USB_MUSB_SUNXI isn't converted yet to DM] Signed-off-by: Tom Rini <trini@konsulko.com>
