This is an init function so move it out of the common header. Avoid using the typedef so that we don't have to include the global_data header file. Also tidy up the function style in comments while we are here. Signed-off-by: Simon Glass <sjg@chromium.org> |

UART: - Dual 4-pins UART serial ports System Logic: - QIXIS-II FPGA system controll 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.

Device tree support and how to enable it for different configs -------------------------------------------------------------- Device tree support is available for t2080qds for below mentioned boot, 1. NOR Boot 2. NAND Boot 3. SD Boot 4. SPIFLASH Boot To enable device tree support for other boot, below configs need to be enabled in relative defconfig file, 1. CONFIG_DEFAULT_DEVICE_TREE="t2080qds" (Change default device tree name if required) 2. CONFIG_OF_CONTROL 3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at CONFIG_RESET_VECTOR_ADDRESS - 0xffc If device tree support is enabled in defconfig, 1. use 'u-boot-with-dtb.bin' for NOR boot. 2. use 'u-boot-with-spl-pbl.bin' for other boot.
