      Fix casting bug in gicv2_main.c · 20d38497
      johpow01 authored 
      

In the function gicv2_set_spi_routing, the signed value proc_num is cast
to unsigned int before being compared to other unsigned values in two
assert calls.  The value proc_num can be a negative value, and once the
negative value is cast to unsigned it becomes a very large number which
will trigger the assert.  This patch changes the assert cast so that the
unsigned values are cast to signed instead, keeping the same functionality
but allowing proc_num to be negative.

This bug can be seen when running the SDEI RM_ANY routing mode test in
TFTF on the Juno platform.

This patch also makes the usage of the proc_num variable in other gicv2
functions more clear.

      drivers: arm: gicv3: Allow detecting number of cores · 79d89e3d
      Andre Przywara authored 
      

A GICv3 interrupt controller will be instantiated for a certain number
of cores. This will result in the respective number of GICR frames. The
last frame will have the "Last" bit set in its GICR_TYPER register.

For platforms with a topology unknown at build time (the Arm FPGAs, for
instance), we need to learn the number of used cores at runtime, to size
the GICR region in the devicetree accordingly.

Add a generic function that iterates over all GICR frames until it
encounters one with the "Last" bit set. It returns the number of cores
the GICv3 has been configured for.

      plat/allwinner: Only enable DRIVEVBUS if really needed · 93fa305c
      Andre Przywara authored 
      

The DRIVEVBUS power rail of the AXP803 PMIC is mostly used to supply
the USB bus power on micro USB sockets, when used in host mode. As this
is a dynamic operation, and mostly we want micro USB sockets to act in
client mode initially, BL31 should not actually enable this power line.
However, on some boards DRIVEVBUS is used to supply power to normal
USB-A sockets. Failing to activate this line there results in
non-functional USB in U-Boot on those boards.

For that reason we were enabling DRIVEVBUS so far, as it did not seem to
cause any harm to the other boards. However it turns out that on the
Pinephone (and other systems with a battery), actually enabling DRIVEVBUS
unconditionally causes serious problems (reboot loop).

To accommodate both use cases, without reverting to a build time option,
check the default OTG configuration in the devicetree. For boards with
USB-A sockets this is set to "host", on boards with micro-B sockets to
"otg". Depending on this setting, we either enable DRIVEVBUS or leave it
alone.

This fixes TF-A on the Pinephone and potentially other battery powered
devices.

      dualroot: add chain of trust for Platform owned SPs · 2947412d
      Manish Pandey authored 
      

For dualroot CoT there are two sets of SP certificates, one owned by
Silicon Provider(SiP) and other owned by Platform. Each certificate can
have a maximum of 4 SPs.

This patch reduces the number of SiP owned SPs from 8 to 4 and adds
the remaining 4 to Plat owned SP.
Plat owned SP certificate is signed using Platform RoT key and
protected against anti-rollback using the Non-trusted Non-volatile
counter.

      plat: marvell: ap807: implement workaround for errata-id 3033912 · 5e4c97d0
      Stefan Chulski authored 
      

ERRATA ID: RES-3033912 - Internal Address Space Init state causes
a hang upon accesses to [0xf070_0000, 0xf07f_ffff]
Workaround: Boot Firmware (ATF) should configure CCU_RGF_WIN(4) to
split [0x6e_0000, 0xff_ffff] to values [0x6e_0000, 0x6f_ffff] and
[0x80_0000, 0xff_ffff] that cause accesses to the segment of
[0xf070_0000, 0xf07f_ffff] to act as RAZWI. Reuse common
work-around code for both AP806 and AP807.

      tbbr/dualroot: rename SP package certificate file · 03a5225c
      Manish Pandey authored 
      

Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.

SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.

This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.

      TF-A GICv2 driver: Introduce makefile · 1322dc94
      Alexei Fedorov authored 
      

This patch moves all GICv2 driver files into new added
'gicv2.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.

NOTE: Usage of 'drivers/arm/gic/common/gic_common.c' file
is now deprecated and platforms with GICv2 driver need to
be modified to include 'drivers/arm/gic/v2/gicv2.mk' in
their makefiles.
