650x80_8000_0000 .. 0xFF_FFFF_FFFF	DDR region #2
66
67Other addresses are either reserved, or not used directly by U-Boot.
68This list should be updated when more addresses are used.

70IFC region map from core's view
71-------------------------------
72During boot i.e. IFC Region #1:-
73  0x30000000 - 0x37ffffff : 128MB : NOR flash
74  0x38000000 - 0x3BFFFFFF : 64MB  : Promjet
75  0x3C000000 - 0x40000000 : 64MB  : FPGA etc
76
77After relocate to DDR i.e. IFC Region #2:-
78  0x5_1000_0000..0x5_1fff_ffff	Memory Hole

92Environment Variables
93---------------------
94- mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined
95  the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.

100Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
101-------------------------------------------------------------------
102One needs to use appropriate bootargs to boot Linux flavors which do
103not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
104below:
105
106=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
107   earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
108   hugepages=16 mem=2048M'

113The X-QSGMII-16PORT is a 4xQSGMII/8xSGMII riser card with eighth SerDes
114interfaces implemented in PCIe form factor board.
115It supports following:
116 - Card can operate with up to 4 QSGMII lane simultaneously
117 - Card can operate with up to 8 SGMII lane simultaneously
118
119Supported card configuration
