PD#150194: mm: update cma policy and debug sysfs
1. For movable memory, using CMA first, this can help to avoid
low memory issue and driver can't allocate pages issue;
2. change /proc/slabinfo sysfs with total size print of each slab;
3. change /proc/pagetypeinfo with toatal pages of each migrate type;
4. add statistics for free pages of each migrate type, and show in
echo m > /proc/sysrq-trigger.

PD#145456: Support RPMB shared secret provisioning [2/2]
[Problem]
RPMB requires a shared secret between host (AP) and device (eMMC flash)
in order to perform HMAC authentication.
[Solution]
This commit provides a special reboot mode, reboot rpmbp, to securely
provision the shared secret into eMMC flash device.
[Test]
Tested on GXL reference board P212. Passed.

PD#146628: crypto update for axg
1. KEY_IV now can only read 16 bytes a time
2. DES is completely disabled and TDES with three identical keys are
also disabled. This creates a potential hole in TDES driver, and
thus TDES support is removed from dts in axg

PD#150373: gcc: add options to limit large object and stack usage
We should restrict limit large size of global object allocated in
driver code to reduce size of .data/.bss/.rodata sections. Also,
large array/many variables declared in a function is not allowed,
this behavior may cause kernel stack overflow especially in IRQ
context or recursion calls.
Right now we just set a very high limit in order to pass comiple.
Final target is to limit:
1. large global object size should not over 4096 bytes, a page size;
2. stack usage of each function should not over 256 bytes.
If your global object is larger than a page size, we advise allocate
it as a static pointer, and allocate it's memory during probe stage.
