| Debug Features: |
| - Support Legacy, COP/JTAG, Aurora, Event and EVT |
| XFI: |
| - XFI is supported on T2080QDS through Lane A/B/C/D on Serdes 1 routed to |
| a on-board SFP+ cages, which to house optical module (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, fm1_10g3, fm1_10g4, 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,fm1_10g3,fm1_10g4" 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. |
| 1000BASE-KX(1G-KX): |
| - T2080QDS can support 1G-KX by using SGMII protocol, but serdes lane |
| runs in 1G-KX mode. By default, the lane runs in SGMII mode, to set a lane |
| in 1G-KX mode, need to set corresponding bit in SerDes Protocol Configuration |
| Register 1 (PCCR1), and U-boot fixup the dtb for kernel to do proper |
| initialization. |
| Hwconfig "fsl_1gkx" is used to indicate a lane runs in 1G-KX mode, MAC |
| 1/2/5/6/9/10 are available for 1G-KX, MAC 3/4 run in RGMII mode. To set a |
| MAC to use 1G-KX mode, set its' corresponding env in "fsl_1gkx", 'fm1_1g1' |
| stands for MAC 1, 'fm1_1g2' stands for MAC 2, etc. |
| For ex. set "fsl_1gkx:fm1_1g1,fm1_1g2,fm1_1g5,fm1_1g6,fm1_1g9,fm1_1g10" in |
| hwconfig, MAC 1/2/5/6/9/10 will use 1G-KX mode. |

| 2-stage NAND/SPI/SD boot loader |
| ------------------------------- |
| PBL initializes the internal CPC-SRAM and copy SPL(160K) to SRAM. |
| SPL further initializes DDR using SPD and environment variables |
| and copy u-boot(768 KB) from NAND/SPI/SD device to DDR. |
| Finally SPL transers control to u-boot for futher booting. |
| |
| SPL has following features: |
| - Executes within 256K |
| - No relocation required |
