-----------------------+------------------------
I build image for wrt1900ac with linaro gcc 4.9 and kernel hangs at
"Starting Kernel...", and everything works when changing to linaro gcc
4.8. It seems something wrong with linaro gcc 4.9.

Step 1: First phase of PEX-PIPE Configuration
Step 2: Configure the desire PIN_PHY_GEN
Step 3 QSGMII enable
Step 4: Configure SERDES MUXes
Step 5: Activate the RX High Impedance Mode
Step 6: [PEX-Only] PEX-Main configuration (X4 or X1)
Step 6.2: [PEX-Only] PCI Express Link Capabilities
Step 7: [PEX-X4 Only] To create PEX-Link
Steps 7,8,9,10 and 11
Steps 12: [PEX-Only] Last phase of PEX-PIPE ConfigurationSteps 13: Wait
