+Pre-Relocation Support
+----------------------
+
+For pre-relocation we simply call the driver model init function. Only
+drivers marked with DM_FLAG_PRE_RELOC or the device tree 'dm,pre-reloc'
+flag are initialised prior to relocation. This helps to reduce the driver
+model overhead.
+
+Then post relocation we throw that away and re-init driver model again.
+For drivers which require some sort of continuity between pre- and
+post-relocation devices, we can provide access to the pre-relocation
+device pointers, but this is not currently implemented (the root device
+pointer is saved but not made available).
+
+
 Things to punt for later
 ------------------------
 
 - SPL support - this will have to be present before many drivers can be
 converted, but it seems like we can add it once we are happy with the
 core implementation.
-- Pre-relocation support - similar story

+That is not to say that no thinking has gone into this - in fact there
 is quite a lot there. However, getting these right is non-trivial and
 there is a high cost associated with going down the wrong path.
 
 For SPL, it may be possible to fit in a simplified driver model with only
 bind and probe methods, to reduce size.

 Uclasses are statically numbered at compile time. It would be possible to
 change this to dynamic numbering, but then we would require some sort of
 lookup service, perhaps searching by name. This is slightly less efficient
