Subject: [PATCH] ieee1275: encode-unit command for 4 addr cell devs
|
|
|
|
Convert physical address to text unit-string.
|
|
|
|
Convert phys.lo ... phys-high, the numerical representation, to unit-string,
|
|
the text string representation of a physical address within the address
|
|
space defined by this device node. The number of cells in the list
|
|
phys.lo ... phys.hi is determined by the value of the #address-cells property
|
|
of this node.
|
|
|
|
This function is for devices with #address-cells == 4
