sunxi: add R528/T113-s3/D1(s) DRAM initialisation code

2023-10-22T22:41:52+00:00

The Allwinner R528/T113-s/D1/D1s SoCs all share the same die, so use the
same DRAM initialisation code.
Make use of prior art here and lift some code from awboot[1], which
carried init code based on earlier decompilation efforts, but with a
GPL2 license tag.
This code has been heavily reworked and cleaned up, to match previous
DRAM routines for other SoCs, and also to be closer to U-Boot's coding
style and support routines.
The actual DRAM chip timing parameters are included in the main file,
since they cover all DRAM types, and are protected by a new Kconfig
CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only
the relevant settings, at build time.

The relevant DRAM chips/board specific configuration parameters are
delivered via Kconfig, so this code here should work for all supported
SoCs and DRAM chips combinations.

drivers: introduce Secure Monitor uclass

2023-10-15T10:23:48+00:00

At the moment, we don't have a common API for working with
SM, only the smc_call() function. This approach is not generic
and difficult to configure and maintain.

This patch adds UCLASS_SM with the generic API:

- sm_call()
- sm_call_write()
- sm_call_read()

These functions operate with struct pt_regs, which describes
Secure Monitor arguments.

arm_ffa: introduce Arm FF-A support

2023-08-08T14:22:03+00:00

Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0

The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.

This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.

The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.

All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.

Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.

The driver exports its operations to be used by upper layers.

Exported operations:

- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap

Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).

For more details please refer to the driver documentation [2].
