Not really. But I have a nice hack to keep it in a working state: diff --git a/cmd/mmc.c b/cmd/mmc.c index 96d81ffdf368..83bd18e34609 100644 --- a/cmd/mmc.c +++ b/cmd/mmc.c @@ -129,10 +129,13 @@ static struct mmc *__init_mmc_device(...) if (!mmc) { printf("no mmc device at slot %x\n", dev); return NULL; } + if (mmc->cfg->host_caps & MMC_CAP_NONREMOVABLE) + force_init = false; + if (!mmc_getcd(mmc)) force_init = true; if (force_init) mmc->has_init = 0;
