Any idea where did this non-removable change come from? I checked the DTS file https://github.com/armbian/build/blob/master/packages/blobs/sunxi/a64/pine64so.dts#L2117 but the non-removable flag is still there in sdmmc@01c0f000 section. But then some changes in DTS files are introduced by kernel patches apparently. The only patch that removes the flag is this one https://github.com/armbian/build/blob/0cdffb29b07305209efb12cf3b5ac6032d3a1153/patch/kernel/archive/sunxi-5.4/patch-5.4.46-47.patch#L44 from 24 March but the Armbian runs Linux 5.10.21-sunxi64 so I can't see how it's even relevant... I would like to create a PR to fix this but I'm a bit confused here.
