From 5df50b8e97377d2468bd8759ec3275e747a147bb Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Wed, 8 Jan 2025 10:25:25 +0100 Subject: [PATCH] hw/sd/sdhci: Set SDHC_NIS_DMA bit when appropriate MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In U-Boot, the fsl_esdhc[_imx] driver waits for both "transmit completed" and "DMA" bits in esdhc_send_cmd_common() by means of DATA_COMPLETE constant. QEMU currently misses to set the DMA bit which causes the driver to loop forever. Fix that by setting the DMA bit if enabled when doing DMA block transfers.
