+ QIXIS System Logic FPGA
+ Manages system power and reset sequencing
+ Manages DUT, board, clock, etc. configuration for dynamic shmoo
+ Collects V-I-T data in background for code/power profiling.
+ Supports legacy TMT test features (POSt, IRS, SYSCLK-synchronous assertion)
+ General fault monitoring and logging
+ Runs from ATX “hot” power rails allowing operation while system is off.
+ Clocks
+ System and DDR clock (SYSCLK, “DDRCLK”)
+ - Switch selectable to one of 16 common settings in the interval 33MHz-166MHz.
+ - Software selectable in 1MHz increments from 1-200MHz.
+ SERDES clocks
+ - Provides clocks to all SerDes blocks and slots
+ - 100, 125 and 156.25 MHz
+ Power Supplies
+ Dedicated regulators for VDD
+ - Adjustable from (0.7V to 1.3V at 80A
+ - Regulators can be controlled by VID and/or software
+ Dedicated regulator for GVDD_PL: 1.35/1.5V at 22A
+ - VTT/MVREF automatically track operating voltage
+ Dedicated regulators/filters for AVDD supplies
+ Dedicated regulators for other supplies: OVDD, BVDD, DVDD, LVDD, POVDD, etc.
+ USB
+ Supports two USB 2.0 ports with integrated PHYs
+ - One type A, one type micro-AB with 1.0A power per port.
+ Other IO
+ eSDHC/MMC
+ - SDHC card slot
+ eSPI port
+ - High-speed serial flash
+ Two Serial port
+ Four I2C ports
+ 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.

+
+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
