Other addresses are either reserved, or not used directly by U-Boot.
This list should be updated when more addresses are used.
IFC region map from core's view
-------------------------------
During boot i.e. IFC Region #1:-
0x30000000 - 0x37ffffff : 128MB : NOR flash
0x38000000 - 0x3BFFFFFF : 64MB : Promjet
0x3C000000 - 0x40000000 : 64MB : FPGA etc
After relocate to DDR i.e. IFC Region #2:-
0x5_1000_0000..0x5_1fff_ffff Memory Hole
0x5_2000_0000..0x5_3fff_ffff IFC CSx (FPGA, NAND and others 512MB)
0x5_4000_0000..0x5_7fff_ffff ASIC or others 1GB
0x5_8000_0000..0x5_bfff_ffff IFC CS0 1GB (NOR/Promjet)
0x5_C000_0000..0x5_ffff_ffff IFC CS1 1GB (NOR/Promjet)

Environment Variables
---------------------
- mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined
the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.
- mcmemsize: MC DRAM block size. If this variable is not defined
the value CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
-------------------------------------------------------------------
One needs to use appropriate bootargs to boot Linux flavors which do
not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
below:
=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
hugepages=16 mem=2048M'
X-QSGMII-16PORT riser card
----------------------------
The X-QSGMII-16PORT is a 4xQSGMII/8xSGMII riser card with eighth SerDes
interfaces implemented in PCIe form factor board.
It supports following:
- Card can operate with up to 4 QSGMII lane simultaneously
- Card can operate with up to 8 SGMII lane simultaneously
Supported card configuration
- CSEL : ON ON ON ON
- MSEL1 : ON ON ON ON OFF OFF OFF OFF
- MSEL2 : OFF OFF OFF OFF ON ON ON ON
To enable this card: modify hwconfig to add "xqsgmii" variable.
