      rockchip: add common aarch32 support · 82e18f89
      Heiko Stuebner authored 
      

There are a number or ARMv7 Rockchip SoCs that are very similar in their
bringup routines to the existing arm64 SoCs, so there is quite a high
commonality possible here.

Things like virtualization also need psci and hyp-mode and instead of
trying to cram this into bootloaders like u-boot, barebox or coreboot
(all used in the field), re-use the existing infrastructure in TF-A
for this (both Rockchip plat support and armv7 support in general).

So add core support for aarch32 Rockchip SoCs, with actual soc support
following in a separate patch.

      rockchip: rk3328: drop double declaration of entry_point storage · 48bea0f3
      Heiko Stuebner authored 
      

The cpuson_entry_point and cpuson_flags are already declared in
plat_private.h so there is no need to have it again declared in
the local pmu.h, especially as it may cause conflicts when the
other type changes.

      rockchip: Allow socs with undefined wfe check bits · 3b5b888d
      Heiko Stuebner authored 
      

Some older socs like the rk3288 do not have the necessary registers
to check the wfi/wfe state of the cpu cores. Allow this case an "just"
do an additional delay similar to how the Linux kernel handles smp
right now.

      rockchip: move pmusram assembler code to a aarch64 subdir · c3aaabaf
      Heiko Stuebner authored 
      

The current code doing power-management from sram is highly
arm64-specific so should live in a corresponding subdirectory
and not in the common area.

      plat/arm: introduce wrapper functions to setup secure watchdog · b0c97daf
      Aditya Angadi authored 
      

The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.

So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.

      Mbed TLS: Remove weak heap implementation · 2374ab17
      Ambroise Vincent authored 
      

The implementation of the heap function plat_get_mbedtls_heap() becomes
mandatory for platforms supporting TRUSTED_BOARD_BOOT.

The shared Mbed TLS heap default weak function implementation is
converted to a helper function get_mbedtls_heap_helper() which can be
used by the platforms for their own function implementation.

      hikey960: Fix race condition between hotplug and idles · 7d76df7d
      Wei Yu authored 
      

From the hotplug testing on Hikey960, in some case cores fail to become
online in the system. When some cores are hotplugged off, if other
cores in the same cluster enter into CPU idle states at the meantime,
the cluster will be powered off. This introduces the state machine
malfunction in the power controller, thus when hotplug on the core
afterwards, it fails to boot up the core because the power controller
thinks the cluster is powered on.

This patch is to avoid race condition between hotplug and idles by
preventing cluster power off when some of cores in the cluster are
hotplugged off, if all cores in the same cluster are hotplugged off,
the cluster can be powered off.
