arm: spl: Allow board_init_r() to run with a larger stack
At present SPL uses a single stack, either CONFIG_SPL_STACK or
CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and
environment) require a lot of stack, some boards set CONFIG_SPL_STACK to
point into SDRAM. They then set up SDRAM very early, before board_init_f(),
so that the larger stack can be used.
This is an abuse of lowlevel_init(). That function should only be used for
essential start-up code which cannot be delayed. An example of a valid use is
when only part of the SPL code is visible/executable, and the SoC must be set
up so that board_init_f() can be reached. It should not be used for SDRAM
init, console init, etc.
Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new
address before board_init_r() is called in SPL.

imx6: Added DEK blob generator command
Freescale's SEC block has built-in Data Encryption
Key(DEK) Blob Protocol which provides a method for
protecting a DEK for non-secure memory storage.
SEC block protects data in a data structure called
a Secret Key Blob, which provides both confidentiality
and integrity protection.
Every time the blob encapsulation is executed,
a AES-256 key is randomly generated to encrypt the DEK.
This key is encrypted with the OTP Secret key
from SoC. The resulting blob consists of the encrypted
AES-256 key, the encrypted DEK, and a 16-bit MAC.
During decapsulation, the reverse process is performed
to get back the original DEK. A caveat to the blob
decapsulation process, is that the DEK is decrypted
in secure-memory and can only be read by FSL SEC HW.
The DEK is used to decrypt data during encrypted boot.

Exynos: Fix L2 cache timings on Exynos5420 and Exynos5800
It was found that the L2 cache timings that we had before could cause
freezes and hangs. We should make things more robust with better
timings. Currently the production ChromeOS kernel applies these
timings, but it's nice to fixup firmware too (and upstream probably
won't take our kernel hacks).
This also provides a big cleanup of the L2 cache init code avoiding
some duplication. The way things used to work:
* low_power_start() was installed by the SPL (both at boot and resume
time) and left resident in iRAM for the kernel to use when bringing
up additional CPUs. It used configure_l2_ctlr() and
configure_l2_actlr() when it detected it was on an A15. This was
needed (despite the L2 cache registers being shared among all A15s)
because we might have been the first man in after the whole A15
cluster was shutdown.
* secondary_cores_configure() was called on at boot time and at resume
time. Strangely this called configure_l2_ctlr() but not
configure_l2_actlr() which was almost certainly wrong. Given that
we'll call both (see next bullet) later in the boot process it
didn't matter for normal boot, but I guess this is how L2 cache
settings got set on 5420/5800 (but not 5250?) at resume time.
* exynos5_set_l2cache_params() was called as part of cache enablement.
This should happen at boot time (normally in the SPL except for USB
boot where it happens in main U-Boot).
Note that the old code wasn't setting ECC/parity in the cache
enablement code but we happened to get it anyway because we'd call
secondary_cores_configure() at boot time. For resume time we'd get it
anyway when the 2nd A15 core came up.
Let's make this a whole lot simpler. Now we always set these
parameters in the same place for all boots and use the same code for
setting up secondary CPUs.
Intended net effects of this change (other than cleanup):
* Timings go from before:
data: 0 cycle setup, 3 cycles (0x2) latency
tag: 0 cycle setup, 3 cycles (0x2) latency
after:
data: 1 cycle setup, 4 cycles (0x3) latency
tag: 1 cycle setup, 4 cycles (0x3) latency
* L2ACTLR is properly initted on 5420/5800 in all cases.
One note is that we're still relying on luck to keep low_power_start()
working. The compiler is being nice and not storing anything on the
stack.
Another note is that on its own this patch won't help to fix cache
settings in an RW U-Boot update where we still have the RO SPL. The
plan for that is:
* Have RW U-Boot re-init the cache right before calling the kernel
(after it has turned the L2 cache off). This is why the functions
are in a header file instead of lowlevel_init.c.
* Have the kernel save the L2 cache settings of the boot CPU and apply
them to all other CPUs. We get a little lucky here because the old
code was using "|=" to modify the registers and all of the bits that
it's setting are also present in the new settings (!). That means
that when the 2nd CPU in the A15 cluster comes up it doesn't
actually mess up the settings of the 1st CPU in the A15 cluster. An
alternative option is to have the kernel write its own
low_power_start() code.

This patch adds code to shutdown secondary cores.

Step-1: After Exynos power-on, primary core starts executing first.
Step-2: In iROM code every core has to check 2 flags i.e.
addresses 0x02020028 & 0x02020004.
Step-3: Initially 0x02020028 is 0 for all cores and 0x02020004 has a
jump address for primary core and 0 for all secondary cores.
Step-4: Therefore, primary core follows normal iROM execution and jumps
to BL1 eventually, whereas all secondary cores enter WFE.
Step-5: When primary core comes into function secondary_cores_configure,
it puts pointer to function power_down_core into 0x02020004
and provides DSB and SEV for all cores so that they may come out
of WFE and jump to power_down_core function.
