386 SPL starts off execution in SRAM and thus typically has only a small

1383 there is no other option. The Ymodem protocol provides a reliable

1409 While we expect to call a pointer to a valid FDT (or NULL)
1410 as the platform parameter to an ATF, some ATF versions are
1411 not U-Boot aware and have an insufficiently robust parameter
1412 validation to gracefully reject a FDT being passed.

1414 If this option is enabled, the spl_atf os-type handler will
1415 always pass NULL for the platform parameter.
