Typical failure rate is 20% on affected boards. This is mitigated by commit 6ecbe1375671 ("drivers: pci: imx: add imx_pcie_remove function"). However, at least on some i.MX6 custom boards, when calling assert_core_reset() as part of the first-time PCIe init, read access to PCIE_PL_PFLR simply hangs. Surround this readl() with imx_pcie_fix_dabt_handler() does not help. For this reason, the forced LTSSM detection is only used on the second assert_core_reset() that is called shorly before starting the Linux kernel.
