|
|
mappings for 32-bit CPUs.
|
|
|
|

The first column indicates the virtual address.
|
|
The second column indicates the physical address.
|
|
The third column indicates the mapped size.

Configuration
|
|
-------------
|
|
|
|
To use the addrmap command you must specify CONFIG_CMD_ADDRMAP=y.
|
|
It is automatically turned on when CONFIG_ADDR_MAP is set.
