      Remove .arch directives from spinlock.S · 02a85c11
      Alexei Fedorov authored 
      

This patch removes .arch "arm8.1-a" and "armv8-a"
directives which overwrite ASFLAGS_aarch64 option based
on ARM_ARCH_MINOR passed to Makefile and cause
translation errors like
"selected processor does not support `bti jc'"
for armv8.5-a targets when BTI support is enabled.

      Add compile-time errors for HW_ASSISTED_COHERENCY flag · 076b5f02
      John Tsichritzis authored 
      This patch fixes this issue:
https://github.com/ARM-software/tf-issues/issues/660



The introduced changes are the following:

1) Some cores implement cache coherency maintenance operation on the
hardware level. For those cores, such as - but not only - the DynamIQ
cores, it is mandatory that TF-A is compiled with the
HW_ASSISTED_COHERENCY flag. If not, the core behaviour at runtime is
unpredictable. To prevent this, compile time checks have been added and
compilation errors are generated, if needed.

2) To enable this change for FVP, a logical separation has been done for
the core libraries. A system cannot contain cores of both groups, i.e.
cores that manage coherency on hardware and cores that don't do it. As
such, depending on the HW_ASSISTED_COHERENCY flag, FVP includes the
libraries only of the relevant cores.

3) The neoverse_e1.S file has been added to the FVP sources.

      Add support for default stack-protector flag · fd7b287c
      Louis Mayencourt authored 
      

The current stack-protector support is for none, "strong" or "all".
The default use of the flag enables the stack-protection to all
functions that declare a character array of eight bytes or more in
length on their stack.
This option can be tuned with the --param=ssp-buffer-size=N option.

      ROMLIB bug fixes · ae2e01b8
      John Tsichritzis authored 
      

Fixed the below bugs:
1) Bug related to build flag V=1: if the flag was V=0, building with
ROMLIB would fail.
2) Due to a syntax bug in genwrappers.sh, index file entries marked as
"patch" or "reserved" were ignored.
3) Added a prepending hash to constants that genwrappers is generating.
4) Due to broken dependencies, currently the inclusion functionality is
intentionally not utilised. This is why the contents of romlib/jmptbl.i
have been copied to platform specific jmptbl.i files. As a result of the
broken dependencies, when changing the index files, e.g. patching
functions, a clean build is always required. This is a known issue that
will be fixed in the future.

      xlat_tables_v2: Revert recent changes to remove recursion · f253645d
      Antonio Nino Diaz authored 
      This commit reverts the following commits:

- c54c7fc3 ("xlat_tables_v2: print xlat tables without recursion")
- db8cac2d ("xlat_tables_v2: unmap region without recursion.")
- 0ffe2692

 ("xlat_tables_v2: map region without recursion.")

This was part of PR#1843.

A problem has been detected in one of our test run configurations
involving dynamic mapping of regions and it is blocking the next
release. Until the problem can be solved, it is safer to revert
the changes.

      Fixup register handling in aarch32 reset_handler · c6c10b02
      Heiko Stuebner authored 
      The BL handover interface stores the bootloader arguments in
registers r9-r12, so when the reset_handler stores the lr pointer
in r10 it clobers one of the arguments.

Adapt to use r8 and adapt the comment about registers allowed
to clober.

I've checked aarch32 reset_handlers and none seem to use higher
registers as far as I can tell.
