   XFI
 	XFI is supported on T4QDS-XFI board which removed slot3 and routed
 	four Lanes A/B/C/D to a SFP+ cages, which to house fiber cable or
 	direct attach cable(copper), the copper cable is used to emulate
 	10GBASE-KR scenario.
 	So, for XFI usage, there are two scenarios, one will use fiber cable,
 	another will use copper cable. An hwconfig env "fsl_10gkr_copper" is
 	introduced to indicate a XFI port will use copper cable, and U-Boot
 	will fixup the dtb accordingly.
 	It's used as: fsl_10gkr_copper:<10g_mac_name>
 	The <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2, they
 	do not have to be coexist in hwconfig. If a MAC is listed in the env
 	"fsl_10gkr_copper", it will use copper cable, otherwise, fiber cable
 	will be used by default.
 	for ex. set "fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2" in
 	hwconfig, then both four XFI ports will use copper cable.
 	set "fsl_10gkr_copper:fm1_10g1,fm1_10g2" in hwconfig, then first two
 	XFI ports will use copper cable, the other two XFI ports will use fiber
 	cable.

 Memory map
 ----------
 The addresses in brackets are physical addresses.

 0x0_0000_0000 (0x0_0000_0000) - 0x0_7fff_ffff   2GB DDR (more than 2GB is initialized but not mapped under with TLB)
 0x0_8000_0000 (0xc_0000_0000) - 0x0_dfff_ffff 1.5GB PCIE memory
 0x0_f000_0000 (0xf_0000_0000) - 0x0_f1ff_ffff  32MB DCSR (includes trace buffers)
 0x0_f400_0000 (0xf_f400_0000) - 0x0_f5ff_ffff  32MB BMan
 0x0_f600_0000 (0xf_f600_0000) - 0x0_f7ff_ffff  32MB QMan
 0x0_f800_0000 (0xf_f800_0000) - 0x0_f803_ffff 256KB PCIE IO
 0x0_e000_0000 (0xf_e000_0000) - 0x0_efff_ffff 256MB NOR flash
 0x0_fe00_0000 (0xf_fe00_0000) - 0x0_feff_ffff  16MB CCSR
 0x0_ffdf_0000 (0xf_ffdf_0000) - 0x0_ffdf_03ff   4KB QIXIS
 0x0_ffff_f000 (0x0_7fff_fff0) - 0x0_ffff_ffff   4KB Boot page translation for secondary cores

 The physical address of the last (boot page translation) varies with the actual DDR size.

 Voltage ID and VDD override
 --------------------
 T4240 has a VID feature. U-Boot reads the VID efuses and adjust the voltage
 accordingly. The voltage can also be override by command vdd_override. The
 syntax is

 vdd_override <voltage in mV>, eg. 1050 is for 1.050v.

 Upon success, the actual voltage will be read back. The value is checked
 for safety and any invalid value will not adjust the voltage.

 Another way to override VDD is to use environmental variable, in case of using
 command is too late for some debugging. The syntax is

 setenv t4240qds_vdd_mv <voltage in mV>
 saveenv
 reset

 The override voltage takes effect when booting.

 Note: voltage adjustment needs to be done step by step. Changing voltage too
 rapidly may cause current surge. The voltage stepping is done by software.
 Users can set the final voltage directly.

 2-stage NAND/SD boot loader
 -------------------------------
 PBL initializes the internal SRAM and copy SPL(160K) in SRAM.
 SPL further initialise DDR using SPD and environment variables
 and copy U-Boot(768 KB) from NAND/SD device to DDR.
 Finally SPL transers control to U-Boot for futher booting.

 SPL has following features:
  - Executes within 256K
  - No relocation required
