Most predefined TLB tables don't have memory coherence bit set for SDRAM. This wasn't an issue before invalidate_dcache_range() function was enabled. Without the coherence bit, dcache invalidation doesn't automatically flush the cache. The coherence bit is already set when dynamic TLB table is used. For some boards with different SPL boot method, or with legacy fixed setting, this bit needs to be set in TLB files. Signed-off-by: York Sun <york.sun@nxp.com> |

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.
