      plat/arm/css/sgm: Reorder early platform init · 2879b5c1
      Girish Pathak authored 
      

In the function, bl1_early_platform_setup in the file
plat/arm/css/sgm/sgm_bl1_setup.c:

  plat_config_init();

  arm_bl1_early_platform_setup();

The debug messages logged by plat_config_init() are lost because
the console is initialized in the function
arm_bl1_early_platform_setup()

To see the logs of plat_config_init, this fix re-orders above calls
so that the console is initialized before call to plat_config_init.

      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.

      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.

      juno: Revert FWU update detect mechanism · 4da6f6cd
      Sathees Balya authored 
      The patch 7b56928a

 unified the FWU mechanism on FVP and Juno
platforms due to issues with MCC firmware not preserving the
NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
writing to the NOR flash while executing from the same flash
in Bypass mode had some stability issues. Hence, since the
MCC firmware issue is resolved, this patch reverts to the
NVFLAGS mechanism to detect FWU. Also, with the introduction
of SDS (Shared Data Structure) by the SCP, the reset syndrome
needs to queried from the appropriate SDS field.

      ARM Platforms:Enable non-secure access to UART1 · 2431d00f
      Alexei Fedorov authored 
      

Adds an undocumented build option that enables non-secure access to
the PL011 UART1.
This allows a custom build where the UART can be used as a serial debug
port for WinDbg (or other debugger) connection.

This option is not documented in the user guide, as it is provided as a
convenience for Windows debugging, and not intended for general use.
In particular, enabling non-secure access to the UART might allow
a denial of service attack!

      Add cache flush after BL1 writes heap info to DTB · 63cc2658
      John Tsichritzis authored 
      

A cache flush is added in BL1, in Mbed TLS shared heap code. Thus, we
ensure that the heap info written to the DTB always gets written back to
memory.  Hence, sharing this info with other images is guaranteed.

      Additional runtime check for DTB presence in BL2 · a606031e
      John Tsichritzis authored 
      

In Mbed TLS shared heap code, an additional sanity check is introduced
in BL2. Currently, when BL2 shares heap with BL1, it expects the heap
info to be found in the DTB. If for any reason the DTB is missing, BL2
cannot have the heap address and, hence, Mbed TLS cannot proceed. So,
BL2 cannot continue executing and it will eventually crash.  With this
change we ensure that if the DTB is missing BL2 will panic() instead of
having an unpredictable crash.

      Slight improvements in Mbed TLS shared heap helpers · 7af2dd2e
      John Tsichritzis authored 
      

This patch, firstly, makes the error messages consistent to how printed
strings are usually formatted. Secondly, it removes an unnecessary #if
directive.
