Previously, the TEG detection branch appended "teg" unconditionally, causing U-Boot to report the device as zu3teg and failing bitstream ID checks for xczu3tcg bitstreams. Check EFUSE_GPU_DIS_MASK in the TEG branch to distinguish the two sub-variants, mirroring the existing EG/CG detection logic: - GPU disabled -> TCG family -> "zu3tcg" - GPU enabled -> TEG family -> "zu3teg" Fixes: fa2f0c97af96 ("soc: zynqmp: Add the IDcode for TEG variant") Signed-off-by: Padmarao Begari Signed-off-by: Michal Simek Link: https://patch.msgid.link/20260623150943.2662500-1-padmarao.begari@amd.com --- diff --git a/drivers/soc/soc_xilinx_zynqmp.c b/drivers/soc/soc_xilinx_zynqmp.c index 4abc73013eb..0e13e230914 100644 --- a/drivers/soc/soc_xilinx_zynqmp.c +++ b/drivers/soc/soc_xilinx_zynqmp.c @@ -358,7 +358,9 @@ static int soc_xilinx_zynqmp_detect_machine(struct udevice *dev, u32 idcode, } else if (device->variants & ZYNQMP_VARIANT_DR_SE) { strlcat(priv->machine, "dr_SE", sizeof(priv->machine)); } else if (device->variants & ZYNQMP_VARIANT_TEG) { - strlcat(priv->machine, "teg", sizeof(priv->machine)); + /* Devices with TEG variant might be TEG or TCG family */ + strlcat(priv->machine, (idcode2 & EFUSE_GPU_DIS_MASK) ? + "tcg" : "teg", sizeof(priv->machine)); } return 0;
