This patch makes the necessary changes to the to support building of

Hence fix is provided so that the tool's makefile get the tool's
binary name from the main makefile instead of overriding it.

plat/arm: Use common build flag for using generic sp804 driver ...

SP804 TIMER is not platform specific, and current code base adds
multiple defines to use this driver. Like FVP_USE_SP804_TIMER and
FVP_VE_USE_SP804_TIMER.

This patch removes platform specific build flag and adds generic
flag `USE_SP804_TIMER` to be set to 1 by platform if needed.

SPM: Alter sp_gen.mk entry depending on owner of partition ...

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
while Plat owned SPs index starts at SP_PKG5_ID.

This patch modifies SP makefile generator script to take CoT as an
argument and if it is "dualroot" then generates SP_PKG in order
mentioned above, otherwise generates it sequentially.

Merge "Use abspath to dereference $BUILD_BASE" into integration

Use abspath to dereference $BUILD_BASE ...

If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.

Openssl directory path is hardcoded to '/usr' in the makefile
of certificate generation and firmware encryption tool using

Fix makefile to build on a Windows host PC ...

The TF-A firmware build system is capable of building on both Unix like
and Windows host PCs. The commit ID 7ff088 "Enable MTE support" updated
the Makefile to conditionally enable the MTE support if the AArch64
architecture revision was greater than 8.5. However, the Makefile changes
were dependent on shell commands that are only available on unix shells,
resulting in build failures on a Windows host PC.

This patch fixes the Makefile by using a more portable approach for
comparing the architecture revision.

Implement workaround for AT speculative behaviour ...

During context switching from higher EL (EL2 or higher)
to lower EL can cause incorrect translation in TLB due to
speculative execution of AT instruction using out-of-context
translation regime.

Workaround is implemented as below during EL's (EL1 or EL2)
"context_restore" operation:
1. Disable page table walk using SCTLR.M and TCR.EPD0 & EPD1
   bits for EL1 or EL2 (stage1 and stage2 disabled)
2. Save all system registers except TCR and SCTLR (for EL1 and EL2)
3. Do memory barrier operation (isb) to ensure all
   system register writes are done.
4. Restore TCR and SCTLR registers (for EL1 and EL2)

Errata details are available for various CPUs as below:
Cortex-A76: 1165522
Cortex-A72: 1319367
Cortex-A57: 1319537
Cortex-A55: 1530923
Cortex-A53: 1530924

More details can be found in mail-chain:
https://lists.trustedfirmware.org/pipermail/tf-a/2020-April/000445.html

Currently, Workaround is implemented as build option which is default
disabled.

Pass more -D options to BL*_CPPFLAGS instead of BL*_CFLAGS ...

Commit d5e97a1d2c79 ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3
globally for C files") does not have commit 848a7e8ce1d9 ("Build:
introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because
they were pulled almost at the same time.

This is a follow-up conversion to be consistent with commit
11a3c5ee7325 ("plat: pass -D option to BL*_CPPFLAGS instead of
BL*_CFLAGS").

With this change, the command line option, IMAGE_AT_EL3, will be
passed to .S files as well.

I remove the definition in include/lib/cpus/aarch64/cpu_macros.S

Otherwise, the following error would happen.
