34 - First USB 3.0 port configured as Host with Type-A connector
35 - Second USB 3.0 port configured as OTG with micro-AB connector
37 - SD Card Rev 2.0 and Rev 3.0
39 - 128 MB high-speed flash Memory for boot code and storage (up to 108MHz)
41 - Two SATA onboard connectors
45 LS2081ARDB board Overview
46 -------------------------
47 LS2081ARDB board is similar to LS2080ARDB board
48 with few differences like
50 - Default boot source is QSPI-boot
51 - Does not have IFC interface
52 - RTC and QSPI flash devices are different
53 - Provides QIXIS access via I2C

70 -------------------------------
71 During boot i.e. IFC Region #1:-
72 0x30000000 - 0x37ffffff : 128MB : NOR flash
73 0x3C000000 - 0x40000000 : 64MB : CPLD
75 After relocate to DDR i.e. IFC Region #2:-
76 0x5_1000_0000..0x5_1fff_ffff Memory Hole
77 0x5_2000_0000..0x5_3fff_ffff IFC CSx (CPLD, NAND and others 512MB)

125 Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
126 -------------------------------------------------------------------
127 One needs to use appropriate bootargs to boot Linux flavors which do
128 not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
131 => setenv bootargs 'console=ttyS1,115200 root=/dev/ram
132 earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
133 hugepages=16 mem=2048M'
