rpi3: Add mem reserve region to DTB if present · 5341b42e

Antonio Nino Diaz authored Oct 19, 2018



When a device tree blob is present at a known address, instead of, for
example, relying on the user modifying the Linux command line to warn
about the memory reserved for the Trusted Firmware, pass it on the DTB.

The current code deletes the memory reserved for the default bootstrap
of the Raspberry Pi and adds the region used by the Trusted Firmware.

This system replaces the previous one consisting on adding
``memmap=16M$256M`` to the Linux command line. It's also meant to be
used by U-Boot and any other bootloader that understands DTB files.

libfdt: Remove current version · b7618c93

Antonio Nino Diaz authored Oct 19, 2018



The current version of libfdt (1.4.2) has been modified to integrate it
in this repository. In order to do a clean import it is needed to remove
the current version first.

juno: Increase BL2 max size · 472158f6

Antonio Nino Diaz authored Oct 23, 2018



Version 1.4.7 of libfdt is bigger than the current one (1.4.2) and the
current reserved space for BL2 in Juno isn't enough to fit the Trusted
Firmware when compiling with clang or armclang.

tzc: Fix MISRA defects · af6491f8

Antonio Nino Diaz authored Oct 15, 2018



The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been
fixed.

The types tzc_region_attributes_t and tzc_action_t have been removed and
replaced by unsigned int because it is not allowed to do logical
operations on enums.

Also, fix some address definitions in arm_def.h.

plat/arm/scmi: introduce plat_css_get_scmi_info API · b911dddc

Chandni Cherukuri authored Oct 11, 2018

The default values of 'plat_css_scmi_plat_info' is not applicable for
all the platforms. There should be a provision to let platform code to
register a platform specific instance of scmi_channel_plat_info_t.

Add a new API 'plat_css_get_scmi_info' which lets the platform to
register a platform specific instance of scmi_channel_plat_info_t and
remove the default values.

In addition to this, the existing 'plat_css_scmi_plat_info' structure
is removed from the common code and instantiated for the platforms that
need it. This allows for a consistent provisioning of the SCMI channel
information across all the existing and upcoming platforms.

Overview
---------

BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)

BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).

During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.

Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.

To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to  BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).

Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.

Leave the caches on and explicitly flush any data that

non-coherent interconnect access which has negative side-
