SD/MMC host controller + 64-bit system bus

Hello! I noticed that the default SD/MMC host controller only supports a 32-bit system bus. Is there a reason 64-bit system buses aren't supported by default? Thanks!

Great!! I'm happy to do so. Thanks for the reply! On Tue, Jun 22, 2021 at 1:51 PM Philippe Mathieu-Daudé wrote: > Hi Joanne, > > On 6/22/21 8:07 PM, Joanne Koong wrote: > > Hello! I noticed that the default SD/MMC host controller only supports a > > 32-bit system bus

[PATCH] hw/sd: sdhci: Enable 64-bit system bus capability in the default SD/MMC host controller

The default SD/MMC host controller uses SD spec v2.00. 64-bit system bus capability was added in v2. In this change, we arrive at 0x157834b4 by computing (0x057834b4 | (1ul << 28)) where 28 represents the BUS64BIT SDHC_CAPAB field. Signed-off-by: Joanne Koong --- hw/sd/sdhci-internal
