      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca339

 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

    mmc: poll eMMC status after EXT_CSD command

    EXT_CSD command needs to access data from eMMC device. Add the
    operation of polling eMMC device status. Make sure the command is
    finished.

A hacked delay time can't fit each eMMC device. Since the above commit
enables the polling operation, remove the hacked delay time now.

      Add plat_crash_console_flush to platforms without it · 9c675b37
      Antonio Nino Diaz authored 
      

Even though at this point plat_crash_console_flush is optional, it will
stop being optional in a following patch.

The console driver of warp7 doesn't support flush, so the implementation
is a placeholder.

TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
they weren't global so they weren't actually used. Also, they were
calling the wrong functions.

imx8_helpers.S only has placeholders for all of the functions.

      poplar: fix build error with POPLAR_RECOVERY=1 · d5ed2946
      Shawn Guo authored 
      Commit eba1b6b3

 ("plat/poplar: migrate to mmc framework") defines
variable 'info' without !POPLAR_RECOVERY protection, and hence causes
the following unused variable error with POPLAR_RECOVERY=1 build.

plat/hisilicon/poplar/bl1_plat_setup.c: In function ‘bl1_platform_setup’:
plat/hisilicon/poplar/bl1_plat_setup.c:95:25: error: unused variable ‘info’ [-Werror=unused-variable]
  struct mmc_device_info info;
                         ^~~~

The patches fixes the build error with POPLAR_RECOVERY=1.

      hikey: Add development TBB support · e59a3bff
      Teddy Reed authored 
      

This patch adds experimental support for TRUSTED_BOARD_BOOT to the
Hikey. This is adapted from the RPi3 and QEMU implementations.

Since the Hikey starts from BL2 the TRUSTED_BOARD_BOOT ROT begins there
too. When TRUSTED_BOARD_BOOT is defined, the BL1 build is skipped.

See the following example:

make \
 PLAT=hikey \
 BL33=u-boot.bin \
 SCP_BL2=mcuimage.bin \
 TRUSTED_BOARD_BOOT=1 \
 MBEDTLS_DIR=../../mbedtls \
 GENERATE_COT=1 \

      Make TF UUID RFC 4122 compliant · 03364865
      Roberto Vargas authored 
      

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.

      types: use int-ll64 for both aarch32 and aarch64 · 0a2d5b43
      Masahiro Yamada authored 
      Since commit 031dbb12

 ("AArch32: Add essential Arch helpers"),
it is difficult to use consistent format strings for printf() family
between aarch32 and aarch64.

For example, uint64_t is defined as 'unsigned long long' for aarch32
and as 'unsigned long' for aarch64.  Likewise, uintptr_t is defined
as 'unsigned int' for aarch32, and as 'unsigned long' for aarch64.

A problem typically arises when you use printf() in common code.

One solution could be, to cast the arguments to a type long enough
for both architectures.  For example, if 'val' is uint64_t type,
like this:

  printf("val = %llx\n", (unsigned long long)val);

Or, somebody may suggest to use a macro provided by <inttypes.h>,
like this:

  printf("val = %" PRIx64 "\n", val);

But, both would make the code ugly.

The solution adopted in Linux kernel is to use the same typedefs for
all architectures.  The fixed integer types in the kernel-space have
been unified into int-ll64, like follows:

    typedef signed char           int8_t;
    typedef unsigned char         uint8_t;

    typedef signed short          int16_t;
    typedef unsigned short        uint16_t;

    typedef signed int            int32_t;
    typedef unsigned int          uint32_t;

    typedef signed long long      int64_t;
    typedef unsigned long long    uint64_t;

[ Linux commit: 0c79a8e29b5fcbcbfd611daf9d500cfad8370fcf ]

This gets along with the codebase shared between 32 bit and 64 bit,
with the data model called ILP32, LP64, respectively.

The width for primitive types is defined as follows:

                   ILP32           LP64
    int            32              32
    long           32              64
    long long      64              64
    pointer        32              64

'long long' is 64 bit for both, so it is used for defining uint64_t.
'long' has the same width as pointer, so for uintptr_t.

We still need an ifdef conditional for (s)size_t.

All 64 bit architectures use "unsigned long" size_t, and most 32 bit
architectures use "unsigned int" size_t.  H8/300, S/390 are known as
exceptions; they use "unsigned long" size_t despite their architecture
is 32 bit.

One idea for simplification might be to define size_t as 'unsigned long'
across architectures, then forbid the use of "%z" string format.
However, this would cause a distortion between size_t and sizeof()
operator.  We have unknowledge about the native type of sizeof(), so
we need a guess of it anyway.  I want the following formula to always
return 1:

  __builtin_types_compatible_p(size_t, typeof(sizeof(int)))

Fortunately, ARM is probably a majority case.  As far as I know, all
32 bit ARM compilers use "unsigned int" size_t.
