[U-Boot] [PATCH] T2080QDS/PCIe: Soft Reset PCIe on T2080QDS for down-training issue

2015-03-10 Thread Zhao Qiang
T2080QDS PEX1/Slot#1 will down-train from x4 to x2, with SRDS_PRTCL_S1 = 0x66 and SRDS_PRTCL_S2 = 0x15. Soft reset PCIe can fix this issue, this is a workaround. Signed-off-by: Zhao Qiang b45...@freescale.com --- drivers/pci/fsl_pci_init.c | 17 + include/configs/T208xQDS.h | 1
