      plat/arm: Fix header dependencies · 234bc7f8
      Antonio Nino Diaz authored 
      

From now on, platform_def.h must include any header with definitions that
are platform-specific (like arm_def.h) and the included headers mustn't
include back platform_def.h, and shouldn't be used by other files. Only
platform_def.h should be included in other files. This will ensure that all
needed definitions are present, rather than needing to include all the
headers in all the definitions' headers just in case.

This also prevents problems like cyclic dependencies.

      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.

      plat/arm: Always define TSP memory region · 07146afb
      Antonio Nino Diaz authored 
      

Even though this is not used unless SPD=tspd, only defining it when
SPD_tspd is defined doesn't have any advantage and it makes it harder to
read the code.

      plat/arm/common: add an additional platform power level · 0e27faf4
      Chandni Cherukuri authored 
      

For platforms using multi-threaded CPUs, there can be upto four
platform power domain levels. At present, there are three platform
power domain levels that are defined for the CSS platforms. Define a
fourth level 'ARM_PWR_LVL3' as well to provide support for an
additional platform power domain level.

      plat/css: allow platforms to define the system power domain level · eff2f444
      Chandni Cherukuri authored 
      

The CSS_SYSTEM_PWR_DMN_LVL macro that defines the system power domain
level is fixed at ARM_PWR_LVL2 for all CSS platforms. However, the
system power domain level can be different for CSS platforms that
use multi-threaded CPUs.

So, in preparation towards adding support for platforms that use
multi-threaded CPUs, refactor the definition of CSS_SYSTEM_PWR_DMN_LVL
such that CSS_SYSTEM_PWR_DMN_LVL is uniquely defined for each of the
CSS platform.

      Standardise header guards across codebase · c3cf06f1
      Antonio Nino Diaz authored 
      

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

      Arm platforms: Fix DRAM address macros · 3d449de0
      Sandrine Bailleux authored 
      

On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently
32-bit values (because they are suffixed with UL and the value
0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When
summing them up, the result overflows the maximum value that can be
encoded in a 32-bit value so it wraps around and does not result in
the expected value.

This patch changes the suffix of these constants into ULL so that they
always are 64-bit values.

- SATA 3.0
- USB 3.0 and USB 2.0
- PCIe
- SDIO (supports boot from eMMC)
- SPI
- UART

      tzc: Fix MISRA defects · af6491f8
      Antonio Nino Diaz authored 
      

The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

      plat/arm: Remove file arm_board_def.h · 0f58d4f2
      Antonio Nino Diaz authored 
      

This file is shared between FVP and all CSS platforms. While it may be
true that some definitions can be common, it doesn't make sense
conceptually. For example, the stack size depends on the platform and so
does the SRAM size.

After removing them, there are not enough common definitions to justify
having this header, so the other definitions have been moved to the
platform_def.h of FVP, board_css_def.h and arm_def.h.

      plat/arm: Move norflash driver to drivers/ folder · aa7877c4
      Antonio Nino Diaz authored 
      

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

      FVP: Reclaim init code for the stack · cb4adb0d
      Daniel Boulby authored 
      

Map the initialization code for BL31 to overlap with the memory
required for the secondary cores stack. Once BL31 has been
initialized the memory can be remapped to RW data so that it can
be used for secondary cores stacks. By moving code from .text to
.text.init the size of the BL31 image is decreased by a page.

Split arm_common.ld.S into two linker scripts, one for tzc_dram
(arm_tzc_dram.ld.S) and one for reclaiming initialization code
(arm_reclaim_init.ld.S) so that platforms can chose which memory
regions they wish to include.

      plat/arm: Remove option ARM_BOARD_OPTIMISE_MEM · c0740e4f
      Antonio Nino Diaz authored 
      

This option makes it hard to optimize the memory definitions of all Arm
platforms because any change in the common defines must work in all of
them. The best thing to do is to remove it and move the definition to
each platform's header.

FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.
