An hwconfig env "fsl_10gkr_copper" is 95 introduced to indicate a XFI port will use copper cable, and U-boot 96 will fixup the dtb accordingly. 97 It's used as: fsl_10gkr_copper:<10g_mac_name> 98 The <10g_mac_name> can be fm1_10g1, fm1_10g2, fm1_10g3, fm1_10g4, they 99 do not have to be coexist in hwconfig. If a MAC is listed in the env 100 "fsl_10gkr_copper", it will use copper cable, otherwise, fiber cable 101 will be used by default. 102 for ex. set "fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm1_10g3,fm1_10g4" in 103 hwconfig, then both four XFI ports will use copper cable. 104 set "fsl_10gkr_copper:fm1_10g1,fm1_10g2" in hwconfig, then first two 105 XFI ports will use copper cable, the other two XFI ports will use fiber 106 cable. 1071000BASE-KX(1G-KX): 108 - T2080QDS can support 1G-KX by using SGMII protocol, but serdes lane 109 runs in 1G-KX mode. By default, the lane runs in SGMII mode, to set a lane 110 in 1G-KX mode, need to set corresponding bit in SerDes Protocol Configuration 111 Register 1 (PCCR1), and U-boot fixup the dtb for kernel to do proper 112 initialization. 113 Hwconfig "fsl_1gkx" is used to indicate a lane runs in 1G-KX mode, MAC 114 1/2/5/6/9/10 are available for 1G-KX, MAC 3/4 run in RGMII mode. To set a 115 MAC to use 1G-KX mode, set its' corresponding env in "fsl_1gkx", 'fm1_1g1' 116 stands for MAC 1, 'fm1_1g2' stands for MAC 2, etc. 117 For ex. set "fsl_1gkx:fm1_1g1,fm1_1g2,fm1_1g5,fm1_1g6,fm1_1g9,fm1_1g10" in 118 hwconfig, MAC 1/2/5/6/9/10 will use 1G-KX mode. 119 120System Memory map 121---------------- 122 123Start Address End Address Description Size 1240xF_FFDF_0000 0xF_FFDF_0FFF IFC - CPLD 4KB 1250xF_FF80_0000 0xF_FF80_FFFF IFC - NAND Flash 64KB 1260xF_FE00_0000 0xF_FEFF_FFFF CCSRBAR 16MB 1270xF_F803_0000 0xF_F803_FFFF PCI Express 4 I/O Space 64KB 1280xF_F802_0000 0xF_F802_FFFF PCI Express 3 I/O Space 64KB 1290xF_F801_0000 0xF_F801_FFFF PCI Express 2 I/O Space 64KB 1300xF_F800_0000 0xF_F800_FFFF PCI Express 1 I/O Space 64KB 1310xF_F600_0000 0xF_F7FF_FFFF Queue manager software portal 32MB 1320xF_F400_0000 0xF_F5FF_FFFF Buffer manager software portal 32MB 1330xF_E800_0000 0xF_EFFF_FFFF IFC - NOR Flash 128MB 1340xF_0000_0000 0xF_003F_FFFF DCSR 4MB 1350xC_4000_0000 0xC_4FFF_FFFF PCI Express 4 Mem Space 256MB 1360xC_3000_0000 0xC_3FFF_FFFF PCI Express 3 Mem Space 256MB 1370xC_2000_0000 0xC_2FFF_FFFF PCI Express 2 Mem Space 256MB 1380xC_0000_0000 0xC_1FFF_FFFF PCI Express 1 Mem Space 512MB 1390x0_0000_0000 0x0_ffff_ffff DDR 4GB 140 141 142128M NOR Flash memory Map 143------------------------- 144Start Address End Address Definition Max size 1450xEFF40000 0xEFFFFFFF u-boot (current bank) 768KB 1460xEFF20000 0xEFF3FFFF u-boot env (current bank) 128KB 1470xEFF00000 0xEFF1FFFF FMAN Ucode (current bank) 128KB 1480xED300000 0xEFEFFFFF rootfs (alt bank) 44MB 1490xEC800000 0xEC8FFFFF Hardware device tree (alt bank) 1MB 1500xEC020000 0xEC7FFFFF Linux.uImage (alt bank) 7MB + 875KB 1510xEC000000 0xEC01FFFF RCW (alt bank) 128KB 1520xEBF40000 0xEBFFFFFF u-boot (alt bank) 768KB 1530xEBF20000 0xEBF3FFFF u-boot env (alt bank) 128KB 1540xEBF00000 0xEBF1FFFF FMAN ucode (alt bank) 128KB 1550xE9300000 0xEBEFFFFF rootfs (current bank) 44MB 1560xE8800000 0xE88FFFFF Hardware device tree (cur bank) 1MB 1570xE8020000 0xE86FFFFF Linux.uImage (current bank) 7MB + 875KB 1580xE8000000 0xE801FFFF RCW (current bank) 128KB 159 160 161 162Software configurations and board settings 163------------------------------------------ 1641.
