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'"
