+Subject: [PATCH] dts: bcm2711: EMMC2 can address the whole first GB
+
+Although 0xfc000000 looks like an inaccessible RAM address (due to the
+peripheral mappings), with RAM mapped at 0xc0000000 (as it is on the
+30/32-bit VPU bus) this is actually 0x3c000000 in the ARM memory space,
+which is fine.
+
+This difference is potentially the cause of some warnings seen in
+sdhci_send_command.
+
+Fixes: "dts: bcm2711: Move emmc2 to its own 'bus'"
