2014-11-19powerpc/t2080qds: fix for 1000BASE-KXShaohui Xie
1000BASE-KX(1G-KX) uses SGMII protocol but the serdes lane runs in 1G-KX mode. By default, the lane runs in SGMII mode, when a MAC uses a lane in 1G-KX mode, corresponding bit in PCCR1 for the lane needs to be set, and needs to fixup dtb accordingly for kernel to do proper initialization. Hwconfig "fsl_1gkx" is used to indicate a MAC runs in 1G-KX mode, FM1 MAC 1/2/5/6/9/10 are available for 1G-KX, MAC 3/4 run in RGMII mode. To set a MAC runs in 1G-KX mode, set its' corresponding env in "fsl_1gkx", 'fm1_1g1' stands for FM1-MAC1, 'fm1_1g2' stands for FM1-MAC2, etc. If all MAC 1/2/5/6/9/10 run in 1G-KX mode, the hwconfig should has below setting: fsl_1gkx:fm1_1g1,fm1_1g2,fm1_1g5,fm1_1g6,fm1_1g9,fm1_1g10 Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> [York Sun: Fix compiling warning] Reviewed-by: York Sun <yorksun@freescale.com>
2014-11-19powerpc/t2080qds: fixup dtb for 10g-krshaohui xie
XFI ports on t2080qds can work with fiber cable and direct attach cable(copper). We use hwconfig to define cable type for XFI, and fixup dtb based on the cable type. For copper cable, set below env in hwconfig: fsl_10gkr_copper:<10g_mac_name> the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm1_10g3, fm1_10g4. fm1_10g1 stands for FM1-MAC9, fm1_10g2 stands for FM1-MAC10, fm1_10g3 stands for FM1-MAC1, fm1_10g4 stands for FM1-MAC2. The four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports, if a given 10G port will use the copper cable for 10GBASE-KR, set the <10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be assumed to be used for the port. For ex. if four XFI ports will both use copper cable, the hwconfig should contain: fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm1_10g3,fm1_10g4 Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
