54IFC region map from core's view
55-------------------------------
56During boot i.e. IFC Region #1:-
57 0x30000000 - 0x37ffffff : 128MB : NOR flash
58 0x3C000000 - 0x40000000 : 64MB : CPLD
59
60After relocate to DDR i.e. IFC Region #2:-
61 0x5_1000_0000..0x5_1fff_ffff Memory Hole
62 0x5_2000_0000..0x5_3fff_ffff IFC CSx (CPLD, NAND and others 512MB)

72Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
73-------------------------------------------------------------------
74One needs to use appropriate bootargs to boot Linux flavors which do
75not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
76below:
77
78=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
79 earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
80 hugepages=16 mem=2048M'
