That's because I used this flag to enable below quirks on AMD NL FPGA
board, and FPGA flag only can be detected on core. Can I set
disable_scramble_quirk, dis_u3_susphy_quirk, and dis_u2_susphy_quirk
for all the FPGA platforms?
if (dwc->amd_nl_plat && dwc->is_fpga) {
dwc->disable_scramble_quirk = true;
dwc->dis_u3_susphy_quirk = true;
dwc->dis_u2_susphy_quirk = true;
}
Thanks,
Rui
