The commit 3eb2d67 optimizes the memory map for BL2 when TSP
is not present. But this also broke OP-TEE as it was reusing
the TSP mapping. This patch fixes this problem by adding a
separate mapping for OP-TEE in the BL2 memory map table.

Due to a bug in the Boot ROM, the USB load API turned out not working
as expected. It is unfixable because the Boot ROM is hard-wired.

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

This patch ensures that the ARM_MAP_TSP_SEC_MEM memory region is mapped
in BL2 only if the TSPD has been included in the build. This saves one
entry in the plat_arm_mmap[] array and avoids to map extra memory when
it's not needed.

This patch fixes the PLAT_LOG_LEVEL_ASSERT to 40 which corresponds
to LOG_LEVEL_INFO. Having this level of log for assertions means that the
`assert()` will not generate the strings implied in the expression taken
as parameter. This allows to save some memory when Juno is built for
LOG_LEVEL = LOG_LEVEL_VERBOSE and DEBUG = 1.

semicolon, which means it's omitted where it's used. This is anomalous

Fix this by removing semicolon from the definition; and where it's a

At present, the MPIDR validation on FVP relies on MT bit set along
with shifted affinities. This currently is additionally dependent
on the FVP model being of variant C. This however should be based
on the presence of MT bit alone.
This patch makes the change to always assume that the affinities
are shifted in the FVP model when MT bit is present.

The nor_XXXXX functions may fail due to different reasons, and it
is convenient to do a full check to detect any failure. It is also
a good idea to have a specific function to do a full status check,
because new checks can be added to this function and they will be
incorporated automatically to any function calling it.

The status register bits remain until explicitly cleared, which means
that a command can be incorrectly considered to have generated an error -
for example, after reset the status register contents may be unknown or
if a previous command had failed.
This patch clears the status register before beginning any command to
be sure that the status register only represents information about the
current operation.

Clear the cpuidle flag when resuming from idle. This flag is set
when entering idle, and if it remains set when resuming, it can
prevent the cluster from powering off during the next system
suspend operation. During system suspend, all CPUs are plugged
out except the last CPU, which is suspended. If any of the
cpuidle flags are set at this point, the last CPU will be stuck
in a WFI loop and will not be powered off.
This problem only occurs during system suspend.

Assembler programmers are used to being able to define functions with a
specific aligment with a pattern like this:
.align X
myfunction:
However, this pattern is subtly broken when instead of a direct label
like 'myfunction:', you use the 'func myfunction' macro that's standard
in Trusted Firmware. Since the func macro declares a new section for the
function, the .align directive written above it actually applies to the
*previous* section in the assembly file, and the function it was
supposed to apply to is linked with default alignment.
An extreme case can be seen in Rockchip's plat_helpers.S which contains
this code:
[...]
endfunc plat_crash_console_putc
.align 16
func platform_cpu_warmboot
[...]
This assembles into the following plat_helpers.o:
Sections:
Idx Name Size [...] Algn
9 .text.plat_crash_console_putc 00010000 [...] 2**16
10 .text.platform_cpu_warmboot 00000080 [...] 2**3
As can be seen, the *previous* function actually got the alignment
constraint, and it is also 64KB big even though it contains only two
instructions, because the .align directive at the end of its section
forces the assembler to insert a giant sled of NOPs. The function we
actually wanted to align has the default constraint. This code only
works at all because the linker just happens to put the two functions
right behind each other when linking the final image, and since the end
of plat_crash_console_putc is aligned the start of platform_cpu_warmboot
will also be. But it still wastes almost 64KB of image space
unnecessarily, and it will break under certain circumstances (e.g. if
the plat_crash_console_putc function becomes unused and its section gets
garbage-collected out).
There's no real way to fix this with the existing func macro. Code like
func myfunc
.align X
happens to do the right thing, but is still not really correct code
(because the function label is inserted before the .align directive, so
the assembler is technically allowed to insert padding at the beginning
of the function which would then get executed as instructions if the
function was called). Therefore, this patch adds a new parameter with a
default value to the func macro that allows overriding its alignment.
Also fix up all existing instances of this dangerous antipattern.
