Shaohui Xie9bf499a2014-08-13 18:19:15 +080082 XFI
83 XFI is supported on T4QDS-XFI board which removed slot3 and routed
84 four Lanes A/B/C/D to a SFP+ cages, which to house fiber cable or
85 direct attach cable(copper), the copper cable is used to emulate
86 10GBASE-KR scenario.
87 So, for XFI usage, there are two scenarios, one will use fiber cable,
88 another will use copper cable. An hwconfig env "fsl_10gkr_copper" is
Bin Menga1875592016-02-05 19:30:11 -080089 introduced to indicate a XFI port will use copper cable, and U-Boot
Shaohui Xie9bf499a2014-08-13 18:19:15 +080090 will fixup the dtb accordingly.
91 It's used as: fsl_10gkr_copper:<10g_mac_name>
92 The <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2, they
93 do not have to be coexist in hwconfig. If a MAC is listed in the env
94 "fsl_10gkr_copper", it will use copper cable, otherwise, fiber cable
95 will be used by default.
96 for ex. set "fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2" in
97 hwconfig, then both four XFI ports will use copper cable.
98 set "fsl_10gkr_copper:fm1_10g1,fm1_10g2" in hwconfig, then first two
99 XFI ports will use copper cable, the other two XFI ports will use fiber
100 cable.

119Voltage ID and VDD override
120--------------------
Bin Menga1875592016-02-05 19:30:11 -0800121T4240 has a VID feature. U-Boot reads the VID efuses and adjust the voltage
York Sun0aadf4a2013-03-25 07:40:01 +0000122accordingly. The voltage can also be override by command vdd_override. The
123syntax is
124
125vdd_override <voltage in mV>, eg. 1050 is for 1.050v.
126
127Upon success, the actual voltage will be read back. The value is checked
128for safety and any invalid value will not adjust the voltage.
129
130Another way to override VDD is to use environmental variable, in case of using
131command is too late for some debugging. The syntax is
132
133setenv t4240qds_vdd_mv <voltage in mV>
134saveenv
135reset
136
137The override voltage takes effect when booting.
138
139Note: voltage adjustment needs to be done step by step. Changing voltage too
140rapidly may cause current surge. The voltage stepping is done by software.
141Users can set the final voltage directly.

1432-stage NAND/SD boot loader
144-------------------------------
145PBL initializes the internal SRAM and copy SPL(160K) in SRAM.
146SPL further initialise DDR using SPD and environment variables
Bin Menga1875592016-02-05 19:30:11 -0800147and copy U-Boot(768 KB) from NAND/SD device to DDR.
148Finally SPL transers control to U-Boot for futher booting.
Shaohui Xieb6036992014-04-22 15:10:44 +0800149
150SPL has following features:
151 - Executes within 256K
152 - No relocation required
