Roberto Vargas 033648652f Make TF UUID RFC 4122 compliant
RFC4122 defines that fields are stored in network order (big endian),
but TF-A stores them in machine order (little endian by default in TF-A).
We cannot change the future UUIDs that are already generated, but we can store
all the bytes using arrays and modify fiptool to generate the UUIDs with
the correct byte order.

Benjamin Fair 529b541e8b drivers: ti: uart: Add TI specific 16550 initialization
On TI platforms the UART is disabled by default and must be explicitly
enabled using the MDR1 register.

NOTE: The original definition of
http://www.ti.com/lit/ds/symlink/pc16550d.pdf has no MDR register, but
many TI SoCs implementing 16550 do have a quirky MDR register
implemented. So, this should be enabled with TI_16550_MDR_QUIRK

NOTE: In such implementation, the CSR register does not exist.

Daniel Boulby 8abcdf921a Ensure read and write of flags are 32 bit
In 'console_set_scope' and when registering a console, field 'flags' of
'console_t' is assigned a 32-bit value. However, when it is actually
used, the functions perform 64-bit reads to access its value. This patch
changes all 64-bit reads to 32-bit reads.

Antonio Nino Diaz c2e05bb78c multi console: Assert that consoles aren't registered twice
In the multi console driver, allowing to register the same console more
than once may result in an infinte loop when putc is called.

If, for example, a boot message is trying to be printed, but the
consoles in the loop in the linked list are runtime consoles, putc will
iterate forever looking for a console that can print boot messages (or
a NULL pointer that will never come).

This loop in the linked list can occur after restoring the system from a
system suspend. The boot console is registered during the cold boot in
BL31, but the runtime console is registered even in the warm boot path.
Consoles are always added to the start of the linked list when they are
registered, so this it what should happen if they were actually
different structures:

   console_list -> NULL
   console_list -> BOOT -> NULL
   console_list -> RUNTIME -> BOOT -> NULL
   console_list -> RUNTIME -> RUNTIME -> BOOT -> NULL

In practice, the two runtime consoles are the same one, so they create
this loop:

   console_list -> RUNTIME -.    X -> BOOT -> NULL
                       ^    |
                       `----'

This patch adds an assertion to detect this problem. The assertion will
fail whenever the same structure tries to be registered while being on
the list.

In order to assert this, console_is_registered() has been implemented.
It returns 1 if the specified console is registered, 0 if not.

Andre Przywara 205cf6e7a5 gicv3: Fix support for systems without secure interrupts
Accessing the interrupt_props array only happens inside a loop over
interrupt_props_num, so the GICv3 driver can cope with no secure
interrupts. This allows us to relax the asserts that insists on
a non-NULL interrupt_props pointer and at least one secure interrupt.
This enables GICv3 platforms which have no need for a secure interrupt.

This only covers the non-deprecated code paths.

Void pointers have been used to access linker symbols, by declaring an
extern pointer, then taking the address of it. This limits symbols
values to aligned pointer values. To remove this restriction an
IMPORT_SYM macro has been introduced, which declares it as a char
pointer and casts it to the required type.

Dan Handley dcf01a0a8d Emit warnings when using deprecated GIC init
Emit runtime warnings when intializing the GIC drivers using the
deprecated method of defining integer interrupt arrays in the GIC driver
data structures; interrupt_prop_t arrays should be used instead. This
helps platforms detect that they have migration work to do. Previously,
no warning was emitted in this case. This affects both the GICv2 and GICv3
drivers.

Also use the __deprecated attribute to emit a build time warning if these
deprecated fields are used. These warnings are suppressed in the GIC
driver compatibility functions but will be visible if platforms use them.

Dan Handley bc1a03c7a6 Improve MULTI_CONSOLE_API deprecation warnings
For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.

This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.

For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.

This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.

Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

This fixes all defects according to MISRA Rule 3.1: "The character

- The link in `sdei_state.c` can also be found in the documentation file

- The bug that the file `io_fip.c` talks about doesn't affect the

  the comment. Note that the version of GCC officially supported is the
  one that comes with Linaro Release 17.10, which is GCC 6.2.

- The link in `tzc400.c` was broken, and it didn't correctly direct to

  by the title of the document, which is more convenient when looking
  for the document.

Fix udelay issues that can make duration slightly too short
2018-01-30 08:59:35 +00:00
Julius Werner e2aec918d0 delay_timer: Guarantee that delay time can never be undershot
Delay functions like udelay() are often used to ensure that the
necessary time passed to allow some asynchronous event to finish, such
as the stabilization delay for a power rail. For these use cases it is
not very problematic if the delay is slightly longer than requested,
but it is critical that the delay must never be shorter.

The current udelay() implementation contains two hazards that may cause
the delay to be slightly shorter than intended: Firstly, the amount of
ticks to wait is calculated with an integer division, which may cut off
the last fraction of ticks needed. Secondly, the delay may be short by a
fraction of a tick because we do not know whether the initial ("start")
sample of the timer was near the start or near the end of the current
tick. Thus, if the code intends to wait for one tick, it might read the
timer value close to the end of the current tick and then read it again
right after the start of the next tick, concluding that the duration of
a full tick has passed when it in fact was just a fraction of it.

This patch rounds up the division and always adds one extra tick to
counteract both problems and ensure that delays will always be larger
but never smaller than requested.

Roberto Vargas 76d2673346 bl2-el3: Don't compile BL1 when BL2_AT_EL3 is defined in FVP
This patch modifies the makefiles to avoid the definition
of BL1_SOURCES and BL2_SOURCES in the tbbr makefiles, and
it lets to the platform makefiles to define them if they
actually need these images. In the case of BL2_AT_EL3
BL1 will not be needed usually because the Boot ROM will
jump directly to BL2.
