ARM: allocate extra space for PSCI stack in secure section during link phase
The PSCI implementation expects at most 2 pages worth of space reserved
at the end of the secure section for its stacks. If PSCI is relocated to
secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.
If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.
This fix allocates the space used by the PSCI stacks in the secure
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.
This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an
explicit symbol.

spl: nand: sunxi: remove support for so-called 'syndrome' mode
The sunxi SPL NAND controller driver supports use 'BootROM'-like configs,
that is, configs where the ECC bytes and real data are interleaved in the
page instead of putting ECC bytes in the OOB area.
Doing that has several drawbacks:
- since you're interleaving data and ECC bytes you can't use the whole page
otherwise you might override the bad block marker with non-FF bytes.
- to solve the bad block marker problem, the ROM code supports partially
using the page, but this introduces a huge penalty both in term of read
speed and NAND memory usage. While this is fine for rather small
binaries(like the SPL one which is at maximum 24KB large), it becomes
non-negligible for the bootloader image (several hundred of KB).
- auto-detection of the page size is not reliable (this is in my opinion
the biggest problem). If you get the page size wrong, you'll end up
reading data at a different offset than what was specified by the caller
and the reading may succeed (if valid data were written at this address).
For all those reasons I think it's wiser to completely remove support for
'syndrome' configs. If we ever need to support it again, then I'd recommend
specifying all the config parameters through Kconfig options.

* The concept of "clocks" and "peripheral clocks" are unified; each clock

clock bindings.
* Clocks are now identified with a single "struct clk", rather than
requiring clients to store the clock provider device and clock identity
values separately. For simple clock consumers, this isolates clients
from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
clk-uclass.h contains the provider API. This aligns with the recently

* clk_ops .of_xlate(), .request(), and .free() are added so providers

requires 64 byte scratch memory in each DRAM channel for the dynamic
training. The memory regions must be reserved in DT before jumping
to the kernel.
The scratch area can be anywhere in each DRAM channel, but the DRAM
init code in SPL currently assigns it at the end of each channel.
So, it makes sense to reserve the regions on run-time by U-Boot
instead of statically embedding it in the DT in Linux. Anyway,

common: env_ubi: Clear environment buffer before reading
In case we have restarted u-boot there is a chance that environment
buffer contains old environment (from the previous boot). If UBI volume
is zero size, ubi_volume_read() doesn't modify the buffer and exits
successfully.
We need to clear buffer manually before reading it from UBI, so the
invalid CRC will cause setting default environment in case that the UBI
volume is zero size.
