From: Simon Glass Date: Thu, 22 Aug 2024 13:54:54 +0000 (-0600) Subject: mmc: Use logging instead of printf() X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=3aa8c443b22cab7f943eddb20aac46ff96214339;p=u-boot.git mmc: Use logging instead of printf() The code makes quite a few uses of __func__ which puts the function name into the resulting SPL image. Use the log subsystem instead, to reduce size. The CONFIG_LOGF_FUNC option can be used to enable the function name. Use lower-case hex for the status output in sdhci_transfer_data(), to match sdhci_send_command() Signed-off-by: Simon Glass Reviewed-by: Quentin Schulz --- diff --git a/drivers/mmc/sdhci.c b/drivers/mmc/sdhci.c index 560b7e889c..4833b5158c 100644 --- a/drivers/mmc/sdhci.c +++ b/drivers/mmc/sdhci.c @@ -32,8 +32,7 @@ static void sdhci_reset(struct sdhci_host *host, u8 mask) sdhci_writeb(host, mask, SDHCI_SOFTWARE_RESET);
