[PATCH v11 1/6] genalloc:support memory-allocation with bytes-alignment to genalloc

[PATCH v11 1/6] genalloc:support memory-allocation with bytes-alignment to genalloc

[Zhao Qiang]

Bytes alignment is required to manage some special RAM,
so add gen_pool_first_fit_align to genalloc,
meanwhile add gen_pool_alloc_data to pass data to
gen_pool_first_fit_align(modify gen_pool_alloc as a wrapper)

Changes for v6:
	- patches set v6 include a new patch because of using 
	- genalloc to manage QE MURAM, patch 0001 is the new 
	- patch, adding bytes alignment for allocation for use.
Changes for v7:
	- cpm muram also need to use genalloc to manage, it has 
	  a function to reserve a specific region of muram,
	  add offset to genpool_data for start addr to be allocated.
Changes for v8:
	- remove supporting reserving a specific region from this patch
	  add a new patch to support it.
Changes for v9:
	- Nil 
Changes for v10:
	- Nil
Changes for v11:
	- Nil

[PATCH v11 4/6] QE/CPM: move muram management functions to qe_common

[Zhao Qiang]

QE and CPM have the same muram, they use the same management
functions. Now QE support both ARM and PowerPC, it is necessary
to move QE to "driver/soc", so move the muram management functions
from cpm_common to qe_common for preparing to move QE code to "driver/soc"
