94f536fc4f arm: mach-keystone: Fixes issue with return values in inline assembly
The inline assembly functions in mon.c assume that the caller will
check for the return value in r0 according to regular ARM calling
conventions.

However, this assumption breaks down if the compiler inlines the
functions. The caller is then under no obligation to use r0 for the
result.

To fix this disconnect, we must explicitly move the return value
from the smc/bl call to the variable that the function returns.

1d73ce6f68 arm: mach-keystone: Updates mon_install for K2G HS
On early K2 devices (eg. K2HK) the secure ROM code does not support
loading secure code to firewall protected memory, before decrypting,
authenticating and executing it.

To load the boot monitor on these devices, it is necessary to first
authenticate and run a copy loop from non-secure memory that copies
the boot monitor behind firewall protected memory, before decrypting
and executing it.

On K2G, the secure ROM does not allow secure code executing from
unprotected memory. Further, ROM first copies the signed and encrypted
image into firewall protected memory, then decrypts, authenticates
and executes it.

As a result of this, we cannot use the copy loop for K2G. The
mon_install has to be modified to pass the address the signed and
encrypted secure boot monitor image to the authentication API.

For backward compatibility with other K2 devices and K2G GP,
the mon_install API still supports a single argument. In this case
the second argument is set to 0 by u-boot and is ignored by ROM

This commit implements the board_fit_image_post_process() function for
the keystone architecture. This function calls into the secure boot
monitor for secure authentication/decryption of the image. All needed
work is handled by the boot monitor and, depending on the keystone
platform, the security functions may be offloaded to other secure
processing elements in the SoC.

The boot monitor acts as the gateway to these secure functions and the
boot monitor for secure devices is available as part of the SECDEV
package for KS2. For more details refer doc/README.ti-secure

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.

Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).

By marking these segments as shared, we also ensure SoC wide coherency
is enabled.

For platforms, which don't have SODIMM with SPD and ddr3 is populated to

u-boot coding style guidance in
http://www.denx.de/wiki/U-Boot/CodingStyle clearly mentions that the
kernel doc style shall be followed for documentation in u-boot.

Current PSC documentation standard does not, so fix that.

up.
