This don't need any special Kconfig option. You just undefine the CONFIG_SPL_FRAMEWORK, and that's all. As fair as I can tell - the CONFIG_SPL_FRAMEWORK option is used with for example imx28evk board. The issue here is that imx28 SoC needs u-boot.sb to boot up when USB is used to debrick it (this is somewhat the legacy approach with a single binary u-boot). > > Regards, > Simon Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-59 Fax: (+49)-8142-66989-80 Email: lu...@denx.de
