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
