d42f265a5d ARM: OMAP3: clock: remove un-used core dpll re-program code
Remove the OMAP3 core DPLL re-program code, and the associated SRAM
code that does the low-level programming of the DPLL divider, idling
of the SDRAM etc.

This code was never fully implemented in the kernel; things missing
were driver side handling of core clock changes (they need to account
for their functional clock rate being changed on-the-fly), and the whole
framework required for handling this. Thus, there is not much point
to keep carrying the low-level support code either.

1306c08a7c ARM: OMAP4+: Remove static iotable mappings for SRAM
In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

8b9a2810b0 ARM: OMAP4+: Move SRAM data to DT
Use drivers/misc/sram.c driver to manage SRAM on all DT only
OMAP platforms (am33xx, am43xx, omap4 and omap5) instead of
the existing private plat-omap/sram.c

Address and size related data  is removed from mach-omap2/sram.c
and now passed to drivers/misc/sram.c from DT.

Users can hence use general purpose allocator apis instead of
OMAP private ones to manage and use SRAM.

edfaf05c2f ARM: OMAP2+: raw read and write endian fix
All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

bb77209432 ARM: OMAP: Move omap2+ specific parts of sram.c to mach-omap2
Let's make the omap2+ specific parts private to mach-omap2.

This leaves just a minimal shared code into plat-omap like
it should be.
