rk3588-pcie_bifurcation_2x2-uboot.patchrk3588-pcie_bifurcation_2x2.patch
Attached are two patches I've prepared. One for uBoot (to correctly recognize split pcie3x4 to two independent controllers, pcie3x4 and pcie3x2),
and one for DT of NanoPC T6.
This basically allows you to use trimmed-down bifurcation adapter. The adapter in question must be trimmed down/cut to fit on the back of the board.
Tested with 2x NVME, and 1xNVME and QCNFA765 wireless card.
I'll post photos later once I'll disconnect the board again from my setup.
BEWARE!!!
If you'd plan to use more than one ath11k wireless card, you'd need QRTR patch. Since the SBL enums changed in recent kernel 6.18.18+,
I am also preparing modified kernel patch (originally for OpenWRT by Hauke Mehrtens and Robert Marko) to allow for more than one ath11k
wireless to be installed. Will post later with new patch for it.
