Resolve build errors flagged by GCC 6.2
With GCC 6.2 compiler, more C undefined behaviour is being flagged as
warnings, which result in build errors in ARM TF build.
The specific issue that this patch resolves is the use of (1 << 31),
which is predominantly used in case statements, where 1 is represented
as a signed int. When shifted to msb the behaviour is undefined.
The resolution is to specify 1 as an unsigned int using a convenience
macro ULL(). A duplicate macro MAKE_ULL() is replaced.

tbbr: Use constant-time bcmp() to compare hashes
To avoid timing side-channel attacks, it is needed to use a constant
time memory comparison function when comparing hashes. The affected
code only cheks for equality so it isn't needed to use any variant of
memcmp(), bcmp() is enough.
Also, timingsafe_bcmp() is as fast as memcmp() when the two compared
regions are equal, so this change incurrs no performance hit in said
case. In case they are unequal, the boot sequence wouldn't continue as
normal, so performance is not an issue.

timingsafe_bcmp() must be used for such operations instead of the

This function executes in constant time and so doesn't leak any timing

*_SIZE + *_MAX_SIZE = *_LIMIT
*_SIZE + *_SIZE = *_END
The _LIMIT is generally defined by platform_def.h to indicate the
platform-dependent memory constraint. So, its typical usage is
ASSERT(. <= BL31_LIMIT, "BL31 image has exceeded its limit.")
in a linker script.
On the other hand, _END is used to indicate the end address of the
compiled image, i.e. we do not know it until the image is linked.
Here, all of these macros belong to the latter, so should be
suffixed with _END.

fiptool: fix add_image() and add_image_desc() implementation
The "make fip" shows the content of the generated FIP at the end of
the build. (This is shown by "fiptool info" command.)
Prior to commit
e0f083a09b29 ("fiptool: Prepare ground for expanding
the set of images at runtime"), the last part of the build log of
make CROSS_COMPILE=aarch64-linux-gnu- BL33=../u-boot/u-boot.bin fip
was like follows:
Trusted Boot Firmware BL2: offset=0xB0, size=0x4188, cmdline="--tb-fw"
EL3 Runtime Firmware BL31: offset=0x4238, size=0x6090, cmdline="--soc-fw"
Non-Trusted Firmware BL33: offset=0xA2C8, size=0x58B51, cmdline="--nt-fw"
With that commit, now it is displayed like follows:
Non-Trusted Firmware BL33: offset=0xB0, size=0x58B51, cmdline="--nt-fw"
EL3 Runtime Firmware BL31: offset=0x58C01, size=0x6090, cmdline="--soc-fw"
Trusted Boot Firmware BL2: offset=0x5EC91, size=0x4188, cmdline="--tb-fw"
You will notice two differences:
- the contents are displayed in BL33, BL31, BL2 order
- the offset values are wrong
The latter is more serious, and means "fiptool info" is broken.
Another interesting change is "fiptool update" every time reverses
the image order. For example, if you input FIP with BL2, BL31, BL33
in this order, the command will pack BL33, BL31, BL2 into FIP, in
this order. Of course, the order of components is not a big deal
except that users will have poor impression about this.
The root cause is in the implementation of add_image(); the
image_head points to the last added image. For example, if you call
add_image() for BL2, BL31, BL33 in this order, the resulted image
chain is:
image_head -> BL33 -> BL31 -> BL2
Then, they are processed from the image_head in "for" loops:
for (image = image_head; image != NULL; image = image->next) {
This means images are handled in Last-In First-Out manner.
Interestingly, "fiptool create" is still correct because
add_image_desc() also reverses the descriptor order and the command
works as before due to the double reverse.
The implementation of add_image() is efficient, but it made the
situation too complicated.
Let's make image_head point to the first added image. This will
add_image() inefficient because every call of add_image() follows
the ->next chain to get the tail. We can solve it by adopting a
nicer linked list structure, but I am not doing as far as that
because we handle only limited number of images anyway.
Do likewise for add_image_desc().

Build: generate .d file at the same time as object is created
Currently, .d files are generated before any objects are built.
So, IS_ANYTHING_TO_BUILD flag is needed to avoid such processing for
non-build targets.
There is a cleverer way; just create a .d file simultaneously when
the corresponding object is created. No need to have separate rules
for .d files.
This commit will also fix a bug; -D$(IMAGE) is defined for $(OBJ),
but not for $(PREREQUISITES). So, .d files are generated with
different macro sets from those for .o files, then wrong .d files
are generated.
For example, in lib/cpus/aarch64/cpu_helpers.S
#if IMAGE_BL31
#include <cpu_data.h>
#endif
<cpu_data.h> is parsed for the object when built for BL31, but the
.d file does not pick up that dependency.
With this commit, the compiler will generate .o and .d at the same
time, guaranteeing they are generated under the same circumstances.

Abort preempted TSP STD SMC after PSCI CPU suspend
Douglas Raillard [Thu, 24 Nov 2016 15:43:19 +0000 (15:43 +0000)]
Abort preempted TSP STD SMC after PSCI CPU suspend
Standard SMC requests that are handled in the secure-world by the Secure
Payload can be preempted by interrupts that must be handled in the
normal world. When the TSP is preempted the secure context is stored and
control is passed to the normal world to handle the non-secure
interrupt. Once completed the preempted secure context is restored. When
restoring the preempted context, the dispatcher assumes that the TSP
preempted context is still stored as the SECURE context by the context
management library.
However, PSCI power management operations causes synchronous entry into
TSP. This overwrites the preempted SECURE context in the context
management library. When restoring back the SECURE context, the Secure
Payload crashes because this context is not the preempted context
anymore.
This patch avoids corruption of the preempted SECURE context by aborting
any preempted SMC during PSCI power management calls. The
abort_std_smc_entry hook of the TSP is called when aborting the SMC
request.
It also exposes this feature as a FAST SMC callable from normal world to
abort preempted SMC with FID TSP_FID_ABORT.

Add provision to extend CPU operations at more levels

for extending the hierarchy for power-down operations. For example,
future CPUs might support multiple threads which might need powering
down individually.
This patch therefore reworks the CPU operations framework to allow for
registering power down handlers on specific level basis. Henceforth:
- Generic code invokes CPU power down operations by the level
required.
- CPU drivers explicitly mention CPU_NO_RESET_FUNC when the CPU has no

- CPU drivers register power down handlers as a list: a mandatory
handler for level 0, and optional handlers for higher levels.
All existing CPU drivers are adapted to the new CPU operations framework
without needing any functional changes within.

tbbr: Fix updating of Non-Trusted NV counter
The previous code required that a certificate be signed with the ROT
key before the platform's NV counter could be updated with the value
in the certificate. This implies that the Non-Trusted NV counter was
not being updated for Non-Trusted content certificates, as they cannot
be signed with the ROT key in the TBBR CoT scheme.
The code is reworked to only allow updating the platform's Trusted NV
counter when a certificate protected by the Trusted NV counter is
signed with the ROT key.
Content certificates protected by the Non-Trusted NV counter are
allowed to update the platform's Non-Trusted NV counter, assuming
that the certificate value is higher than the platform's value.
A new optional platform API has been introduced, named
plat_set_nv_ctr2(). Platforms may choose to implement it and perform
additional checks based on the authentication image descriptor before
modifying the NV counters. A default weak implementation is available
