You're welcome. (Unrelated) Note that I added a console= and earlycon in my test (and got the baud rate wrong for the console but nevermind...was ssh'd in after the earlycon output I cared about anyway) because of some other cleanup work for the SPCR parsing that apparently is still not quite fixed for upstream, or rather, there is a need to match on the 32-bit access required for the UART and that isn't happening so it's not getting setup. Folks are tracking that one and fixing it though. -- Computer Architect | Sent from my 64-bit #ARM Powered phone > On Dec 2, 2016, at 02:37, Duc Dang <dhdang@xxxxxxx> wrote: > >> On Thu, Dec 1, 2016 at 11:12 PM, Jon Masters <jcm@xxxxxxxxxx> wrote: >>> On 12/01/2016 09:27 PM, Duc Dang wrote: >>> PCIe controllers in X-Gene SoCs is not ECAM compliant: software >>> needs to configure additional controller's register to address >>> device at bus:dev:function. >>> >>> The quirk will discover controller MMIO register space and configure >>> controller registers to select and address the target secondary device. >>> >>> The quirk will only be applied for X-Gene PCIe MCFG table with >>> OEM revison 1, 2, 3 or 4 (PCIe controller v1 and v2 on X-Gene SoCs). >>> >>> Signed-off-by: Duc Dang <dhdang@xxxxxxx> >> >> So far I've tested this on an HPE ProLiant m400 (Moonshot) cartridge >> and will test it on some other reference platforms soon.
