* Asynchronous External Abort with syndrome 0xbf000002 on Cortex A53
* core means SError interrupt caused by AXI SLVERR on external access.
*
* In most cases this indicates a bug in U-Boot or Linux kernel driver
* pci-aardvark.c which implements access to A3700 PCIe config space.
* Driver does not wait for PCIe PIO transfer completion and try to
* start a new PCIe PIO transfer while previous has not finished yet.
* A3700 PCIe controller in this case sends SLVERR via AXI which results
* in a fatal Asynchronous SError interrupt on Cortex A53 CPU.
*
* Following patches fix that bug in U-Boot and Linux kernel drivers:
* https://source.denx.de/u-boot/u-boot/-/commit/eccbd4ad8e4e182638eafbfb87ac139c04f24a01
* https://git.kernel.org/stable/c/f18139966d072dab8e4398c95ce955a9742e04f7
*
* As a hacky workaround for unpatched U-Boot and Linux kernel drivers
* ignore all asynchronous aborts with that syndrome value received on
* CPU from level lower than EL3.
*
* Because these aborts are delivered on CPU asynchronously, they are
* imprecise and we cannot check the real reason of abort and neither
* who and why sent this abort. We expect that on A3700 it is always
* PCIe controller.
*
* Hence ignoring all aborts with this syndrome value is just a giant
* hack that we need only because of bugs in old U-Boot and Linux kernel
* versions and because it was decided that TF-A would implement this
* hack for U-Boot and Linux kernel it in this way. New patched U-Boot
* and kernel versions do not need it anymore.
*
* Links to discussion about this workaround:
* https://lore.kernel.org/linux-pci/20190316161243.29517-1-repk@triplefau.lt/
