[U-Boot] [PATCH v2 0/5] [3/3] Initial support Texas Instrument's AM654 Platform

[Lokesh Vutla]

Continue from PART 2/3...

This series adds arm64 support for AM654 EVM. Patch 2/6 describes the
boot flow in detail. I would recommend to go through the patch in order
to understand the entire boot flow.

Right now only arm64 support is added. r5 support will be posted later
once loading of system firmware is ported to generic filesystem loader.

Changes since v1:
- Merged adding readme patch[2/6] to board support patch[1/6]
- Updated more info on the boot flow.

[U-Boot] [PATCH v2 1/5] board: ti: am654: a53: Add initial support for am654

[Lokesh Vutla]

Add initial support for AM654 based EVM running on A53. Enable
4GB of DDR available on the EVM so that kernel DTB file
can be updated accordingly.

+Introduction:
+-------------
+The AM65x family of SoCs is the first device family from K3 Multicore
+SoC architecture, targeted for broad market and industrial control with
+aim to meet the complex processing needs of modern embedded products.
+
+The device is built over three domains, each containing specific processing
+cores, voltage domains and peripherals:
+1. Wake-up (WKUP) domain:
+	- Device Management and Security Controller (DMSC)
+2. Microcontroller (MCU) domain:
+	- Dual Core ARM Cortex-R5F processor
+3. MAIN domain:
+	- Quad core 64-bit ARM Cortex-A53
+
+More info can be found in TRM: http://www.ti.com/lit/pdf/spruid7
+
+Boot Flow:
+----------
+On AM65x family devices, ROM supports boot only via MCU(R5). This means that
+bootloader has to run on R5 core. In order to meet this constraint, and for
+the following reasons the boot flow is designed as mentioned:
+1. Need to move away from R5 asap, so that we want to start *any*
+firmware on the r5 cores like.... autosar can be loaded to receive CAN
+response and other safety operations to be started. This operation is
+very time critical and is applicable for all automotive use cases.
+2. U-Boot on A53 should start other remotecores for various
+applications. This should happen before running Linux.
+3. In production boot flow, we might not like to use full u-boot,
+instead use Flacon boot flow to reduce boot time.

+Build procedure:
+----------------

[U-Boot] [PATCH v2 2/5] include: am654_evm: Establish initial environment for SD card boot

[Lokesh Vutla]

From: Andreas Dannenberg <dannenberg@ti.com>

Create a basic U-Boot environment that allows the automatic loading
of a Linux Kernel located at /boot/Image and an associated device tree
blob located at /boot/k3-am654-base-board.dtb from the secondary
partition of an ext4-formatted SD card on the AM654x EVM. Furthermore
the boot.scr and uEnv.txt detection and loading schemes are supported
in a manner already known from other TI platforms.

Note that this is intended to be a starting point to enable initial
board use and will most certainly get extended and refactored as
different boot media become available.
