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.
