Some systems have so much RAM that the end of RAM is beyond 4GB. An
example would be a Tegra124 system (where RAM starts at 2GB physical)
that has more than 2GB of RAM.
In this case, we can gd->ram_size to represent the actual RAM size, so
that the actual RAM size is passed to the OS. This is useful if the OS
implements LPAE, and can actually use the "extra" RAM.
However, U-Boot does not implement LPAE and so must deal with 32-bit
physical addresses. To this end, we enhance board_get_usable_ram_top() to
detect the "over-sized" case, and limit the relocation addres so that it
fits into 32-bits of physical address space.

Since more than one board requires memory reservation
for the secure firmware, the reservation code can be
made in a common code.
Now, to reserve some part of the the last bank,
board config should define:
- CONFIG_TZSW_RESERVED_DRAM - len in bytes
- CONFIG_NR_DRAM_BANKS - number of memory banks

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.
Commands added
--------------
dek_blob - encapsulating DEK as a cryptgraphic blob
Commands Syntax
---------------
dek_blob src dst len
Encapsulate and create blob of a len-bits DEK at
address src and store the result at address dst.

Add a specific relocate_vectors macro that skips the vector relocation, as the

Each way of the system cache has 256 entries for PH1-Pro4 and older
SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs. The line
size is still 128 byte. Thus, the way size is 32KB/64KB for old/new
SoCs.
To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the
constant value 32KB. It is large enough for temporary RAM and
should work for all the SoCs of UniPhier family.

This function was intended for MN2WS0235 (what we call PH1-Pro4TV).
On that SoC, MPLL is already running on the power-on reset and it
makes sense to stop the PLL at early boot-up.
On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register,
so this function has no point.
