86Debug Features:
87 - Support Legacy, COP/JTAG, Aurora, Event and EVT
88XFI:
89 - XFI is supported on T2080QDS through Lane A/B/C/D on Serdes 1 routed to
90 a on-board SFP+ cages, which to house optical module (fiber cable) or
91 direct attach cable(copper), the copper cable is used to emulate
92 10GBASE-KR scenario.
93 So, for XFI usage, there are two scenarios, one will use fiber cable,
94 another will use copper cable. 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.

2152-stage NAND/SPI/SD boot loader
216-------------------------------
217PBL initializes the internal CPC-SRAM and copy SPL(160K) to SRAM.
218SPL further initializes DDR using SPD and environment variables
219and copy U-Boot(768 KB) from NAND/SPI/SD device to DDR.
220Finally SPL transers control to U-Boot for futher booting.
221
222SPL has following features:
223 - Executes within 256K
224 - No relocation required

276Device tree support and how to enable it for different configs
277--------------------------------------------------------------
278Device tree support is available for t2080qds for below mentioned boot,
2791. NOR Boot
2802. NAND Boot
2813. SD Boot
2824. SPIFLASH Boot
283
284To enable device tree support for other boot, below configs need to be
285enabled in relative defconfig file,
2861. CONFIG_DEFAULT_DEVICE_TREE="t2080qds" (Change default device tree name if required)
2872. CONFIG_OF_CONTROL
2883. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at
289   CONFIG_RESET_VECTOR_ADDRESS - 0xffc
290
291If device tree support is enabled in defconfig,
2921. use 'u-boot-with-dtb.bin' for NOR boot.
2932. use 'u-boot-with-spl-pbl.bin' for other boot.
294
