Hi,
On.. drivers/mmc/sdhci.c
if (caps & SDHCI_CAN_DO_8BIT)mmc->host_caps |= MMC_MODE_8BIT;Here we are setting 8BIT bus width, if the sdhci capabilities register 18
bit is set.
Does 18-bit is really denoted for 8-bit bus width, I cound't find it on
spec, https://www.sdcard.org/developers/overview/host_controller/simple_spec/Simpl ified_SD_Host_Controller_Spec.pdf
Dear Jagannadha Sutradharudu Teki,
The current u-boot SD/MMC driver supports the latest SD Specification. You should read version 3.0 of the specification.
OK, i saw the spec thanks. I think we need to add the fix on sdhci, for backward compatibility. Any concerns.
Thanks, Jagan.
