OMAP platforms(like OMAP3530) include DSP or other co-processors
for media acceleration. when carving out memory for the
accelerators we can end up creating a hole in the memory map
of sort:
<kernel memory><hole(memory for accelerator)><kernel memory>
To handle such a memory configuration ARCH_HAS_HOLES_MEMORYMODEL
has to be enabled. For further information refer discussion at:
http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxx/msg15262.html.
pls check the link: I see "The document you were looking for was not

The URL is spelt incorrectly. Here is the correct URL:
http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg15262.html
select GENERIC_TIME
select GENERIC_CLOCKEVENTS
+ select ARCH_HAS_HOLES_MEMORYMODEL
why enable this for all OMAPs?
I have tested this on several OMAP3 platforms and this feature is required
Wherever some memory needs to be reserved for media accelerators - hence it
Would be handy for earlier OMAP platforms as well
I understand that you have tested with OMAP3. my question is you have
handled this as per the diff
@@ -699,6 +699,7 @@ config ARCH_OMAP
to ARCH_OMAP
is this good for OMAP1510, 1610, 1710, 2420,2430, 770 etc..?
if this is an OMAP3 requirement why not add it there?
