      plat/arm: Introduce corstone700 platform. · 7bdc4698
      Manish Pandey authored 
      

This patch adds support for Corstone-700 foundation IP, which integrates
both Cortex-M0+ and Cortex-A(Host) processors in one handy, flexible
subsystem.
This is an example implementation of Corstone-700 IP host firmware.

Cortex-M0+ will take care of boot stages 1 and 2(BL1/BL2) as well as
bringing Host out RESET. Host will start execution directly from BL32 and
then will jump to Linux.

It is an initial port and additional features are expected to be added
later.

      FVP: Add Delay Timer driver to BL1 and BL31 · 1b597c22
      Alexei Fedorov authored 
      

SMMUv3 driver functions which are called from BL1 and BL31
currently use counter-based poll method for testing status
bits. Adding Delay Timer driver to BL1 and BL31 is required
for timeout-based implementation using timer delay functions
for SMMU and other drivers.
This patch adds new function `fvp_timer_init()` which
initialises either System level generic or SP804 timer based on
FVP_USE_SP804_TIMER build flag.
In BL2U `bl2u_early_platform_setup()` function the call to
`arm_bl2u_early_platform_setup()` (which calls
`generic_delay_timer_init()` ignoring FVP_USE_SP804_TIMER flag),
is replaced with `arm_console_boot_init()` and `fvp_timer_init()`.

      rockchip: rk3399: store actual debug uart information on suspend · 0eb7fa91
      Heiko Stuebner authored 
      

The rk3399 suspend code saves and restores the debug uart settings, but
right now always does this for the default uart. Right now this works
only by chance for the majority of rk3399 boards, which do not deviate
from that default.

But both Coreboot as well as U-Boot-based platforms can actually use
different uarts for their output, which can be configured from either
devicetree or Coreboot-variables.

To fix this, just use the stored uart-base information instead of the
default constant.

      rockchip: move dt-coreboot uart distinction into param handling code · dd4a0d16
      Heiko Stuebner authored 
      

Rockchip platforms can be booted from either u-boot or coreboot.

So far the Coreboot-console was initizalized from a coreboot data struct
in the early_param2 callbacks and dt-based consoles with data from the
rockchip_get_uart_* functions.

But later code may also need this console information for example for
special suspend handling. To make this easy follow a suggestion from
Julius Werner and move the coreboot<->dt distinction into the
rockchip_get_uart_* functions, thus making correct data about the used
uart available to all Rockchip platform code at all times.

This includes a new rockchip_get_uart_clock as well, because while the
dt-platforms right now always just default the rate defined in a constant
Coreboot provides its own field for the clock rate and we don't want to
loose that information for the console init. Similarly the rk_uart_*
variables should move into the non-Coreboot code, to prevent them from
being marked as unused, which also requires the rk_get_uart_* functions
to move below the actual dt-parsing.

      rockchip: make uart baudrate configurable · 30970e0f
      Heiko Stuebner authored 
      

A previous patch already allowed to configure the uart output from the
devicetree, but on Rockchip platforms we also have the issue of different
vendors using different baudrates for their uarts.

For example, rk3399 has a default baudrate of 115200 which is true for
ChromeOS-devices and boards from Theobroma-Systems, while all the boards
using the vendor boot chain actually use a baudrate of 1500000.

Similarly the newly added px30 has a default of said 1500000 but some
boards may want to use the more widely used 115200.

The devicetree stdout-path node already contains the desired baudrate,
so add simple code to parse it from there and override the default,
which stays unchanged.

      rockchip: px30: add uart5 as option for serial output · 5f441a7b
      Heiko Stuebner authored 
      

The px30 mini-evb can use either uart2 (muxed with the sd-card pins) or
uart5 via its pin header for serial output. Uart5 is especially useful
when needing to boot from the sd-card, where uart2 obviously is not
useable.

So add the uart5 constants and it as uart option for the serial-param
handler.

      meson: gxl: Fix CPU hotplug · b4694a86
      Remi Pommarel authored 
      

The CPU[1-3] are reset to initial/cold boot state (with their reset
address set to 0x0). In this state the cpus are waiting for another
one to set the reset address to bl31_warm_entrypoint and wake them up.

The CPU0 needs a bit of a workaround as changing the reset address
either through PSCI mailbox or the mmio mapped RVBAR (at 0xda834650)
does not seem to have any effect. Thus the workaround consists in
emulating the other CPUs' behavior with a WFE loop and manually jumping
to bl31_warm_entrypoint when woken back up by another one.

Before CPU enters standby state (wfi), the AP needs to signal the SCP
through PSCI mailbox.

Also at boot time the AP has to wait for the SCP to be ready before
sending the first scpi commands or it can crash.

      Switch AARCH32/AARCH64 to __aarch64__ · 402b3cf8
      Julius Werner authored 
      

NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.

All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.
