I have a nitrogen 6x (solo not quad) and have questions regarding the uboot PCIE support. Ive found a few posts saying it is in fact added, ive also found the "validation system" documentation found in the I.MX_6Dual6Quad_Linux_Ref manual.
In the validation system is talks about certain settings such as "
# CONFIG_IMX_PCIE_EP_MODE_IN_EP_RC_SYS is not set
However i do not find these settings in buildroot under make menuconfig. Is there a different system or set of menus where i am missing the pcie configuration options?
