doc: board: ti: Update documentation for binman flow

Earlier documentation specified builds for generating bootloader images
using an external TI repository k3-image-gen and core-secdev-k3. Modify
this to using the binman flow so that user understands how to build the
final boot images.

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.

eMMC:
-----
ROM supports booting from eMMC from boot0 partition offset 0x0
Flashing images to eMMC:
The following commands can be used to download tiboot3.bin, tispl.bin,
u-boot.img, and sysfw.itb from an SD card and write them to the eMMC boot0
partition at respective addresses.
=> mmc dev 0 1
=> fatload mmc 1 ${loadaddr} tiboot3.bin
=> mmc write ${loadaddr} 0x0 0x400
=> fatload mmc 1 ${loadaddr} tispl.bin
=> mmc write ${loadaddr} 0x400 0x1000
=> fatload mmc 1 ${loadaddr} u-boot.img
=> mmc write ${loadaddr} 0x1400 0x2000
=> fatload mmc 1 ${loadaddr} sysfw.itb
=> mmc write ${loadaddr} 0x3600 0x800
To give the ROM access to the boot partition, the following commands must be
used for the first time:
=> mmc partconf 0 1 1 1
=> mmc bootbus 0 1 0 0
To create a software partition for the rootfs, the following command can be
used:
=> gpt write mmc 0 ${partitions}
eMMC layout:
boot0 partition (8 MB) user partition
0x0+----------------------------------+ 0x0+-------------------------+
| tiboot3.bin (512 KB) | | |
0x400+----------------------------------+ | |
| tispl.bin (2 MB) | | |
0x1400+----------------------------------+ | rootfs |
| u-boot.img (4 MB) | | |
0x3400+----------------------------------+ | |
| environment (128 KB) | | |
0x3500+----------------------------------+ | |
| backup environment (128 KB) | | |
0x3600+----------------------------------+ | |
| sysfw (1 MB) | | |
0x3E00+----------------------------------+ +-------------------------+
Kernel image and DT are expected to be present in the /boot folder of rootfs.
To boot kernel from eMMC, use the following commands:
=> setenv mmcdev 0
=> setenv bootpart 0
=> boot
OSPI:
-----
ROM supports booting from OSPI from offset 0x0.
Flashing images to OSPI:
Below commands can be used to download tiboot3.bin, tispl.bin, u-boot.img,
and sysfw.itb over tftp and then flash those to OSPI at their respective
addresses.
=> sf probe
=> tftp ${loadaddr} tiboot3.bin
=> sf update $loadaddr 0x0 $filesize
=> tftp ${loadaddr} tispl.bin
=> sf update $loadaddr 0x80000 $filesize
=> tftp ${loadaddr} u-boot.img
=> sf update $loadaddr 0x280000 $filesize
=> tftp ${loadaddr} sysfw.itb
=> sf update $loadaddr 0x6C0000 $filesize
Flash layout for OSPI:
0x0 +----------------------------+
| ospi.tiboot3(512K) |
| |
0x80000 +----------------------------+
| ospi.tispl(2M) |
| |
0x280000 +----------------------------+
| ospi.u-boot(4M) |
| |
0x680000 +----------------------------+
| ospi.env(128K) |
| |
0x6A0000 +----------------------------+
| ospi.env.backup (128K) |
| |
0x6C0000 +----------------------------+
| ospi.sysfw(1M) |
| |
0x7C0000 +----------------------------+
| padding (256k) |
0x800000 +----------------------------+
| ospi.rootfs(UBIFS) |
| |
+----------------------------+
Kernel Image and DT are expected to be present in the /boot folder of UBIFS
ospi.rootfs just like in SD card case. U-Boot looks for UBI volume named
"rootfs" for rootfs.
To boot kernel from OSPI, at the U-Boot prompt:
=> setenv boot ubi
=> boot
UART:
-----
ROM supports booting from MCU_UART0 via X-Modem protocol. The entire UART-based
boot process up to U-Boot (proper) prompt goes through different stages and uses
different UART peripherals as follows:
WHO | Loading WHAT | HW Module | Protocol
----------+---------------+-------------+------------
Boot ROM | tiboot3.bin | MCU_UART0 | X-Modem(*)
R5 SPL | sysfw.itb | MCU_UART0 | Y-Modem(*)
R5 SPL | tispl.bin | MAIN_UART0 | Y-Modem
A53 SPL | u-boot.img | MAIN_UART0 | Y-Modem
(*) Note that in addition to X/Y-Modem related protocol timeouts the DMSC
watchdog timeout of 3min (typ.) needs to be observed until System Firmware
is fully loaded (from sysfw.itb) and started.
Example bash script sequence for running on a Linux host PC feeding all boot
artifacts needed to the device:
MCU_DEV=/dev/ttyUSB1
MAIN_DEV=/dev/ttyUSB0
stty -F $MCU_DEV 115200 cs8 -cstopb -parenb
stty -F $MAIN_DEV 115200 cs8 -cstopb -parenb
sb --xmodem tiboot3.bin > $MCU_DEV < $MCU_DEV
sb --ymodem sysfw.itb > $MCU_DEV < $MCU_DEV
sb --ymodem tispl.bin > $MAIN_DEV < $MAIN_DEV
sleep 1
sb --xmodem u-boot.img > $MAIN_DEV < $MAIN_DEV

To give the ROM access to the boot partition, the following commands must be
used for the first time:
.. code-block:: text
=> mmc partconf 0 1 1 1
=> mmc bootbus 0 1 0 0
To create a software partition for the rootfs, the following command can be
used:
.. code-block:: text
=> gpt write mmc 0 ${partitions}

.. code-block:: text

Kernel image and DT are expected to be present in the /boot folder of rootfs.
To boot kernel from eMMC, use the following commands:
.. code-block:: text
=> setenv mmcdev 0
=> setenv bootpart 0
=> boot
OSPI:
-----
ROM supports booting from OSPI from offset 0x0.
Flashing images to OSPI:
Below commands can be used to download tiboot3.bin, tispl.bin, u-boot.img,
and sysfw.itb over tftp and then flash those to OSPI at their respective
addresses.
.. code-block:: text
=> sf probe
=> tftp ${loadaddr} tiboot3.bin
=> sf update $loadaddr 0x0 $filesize
=> tftp ${loadaddr} tispl.bin
=> sf update $loadaddr 0x80000 $filesize
=> tftp ${loadaddr} u-boot.img
=> sf update $loadaddr 0x280000 $filesize
=> tftp ${loadaddr} sysfw.itb
=> sf update $loadaddr 0x6C0000 $filesize
Flash layout for OSPI:
.. code-block:: text

| ospi.tiboot3(512K) |
| |
0x80000 +----------------------------+
| ospi.tispl(2M) |

0x7C0000 +----------------------------+
| padding (256k) |
0x800000 +----------------------------+
| ospi.rootfs(UBIFS) |
| |
+----------------------------+
Kernel Image and DT are expected to be present in the /boot folder of UBIFS
ospi.rootfs just like in SD card case. U-Boot looks for UBI volume named
"rootfs" for rootfs.
To boot kernel from OSPI, at the U-Boot prompt:
.. code-block:: text
=> setenv boot ubi
=> boot
UART:
-----
ROM supports booting from MCU_UART0 via X-Modem protocol. The entire UART-based
boot process up to U-Boot (proper) prompt goes through different stages and uses
different UART peripherals as follows:
.. code-block:: text
+---------+---------------+-------------+------------+
| WHO | Loading WHAT | HW Module | Protocol |
+---------+---------------+-------------+------------+
|Boot ROM | tiboot3.bin | MCU_UART0 | X-Modem(*)|
|R5 SPL | sysfw.itb | MCU_UART0 | Y-Modem(*)|
|R5 SPL | tispl.bin | MAIN_UART0 | Y-Modem |
|A53 SPL | u-boot.img | MAIN_UART0 | Y-Modem |
+---------+---------------+-------------+------------+
Note that in addition to X/Y-Modem related protocol timeouts the DMSC
watchdog timeout of 3min (typ.) needs to be observed until System Firmware
is fully loaded (from sysfw.itb) and started.
Example bash script sequence for running on a Linux host PC feeding all boot
artifacts needed to the device:
.. code-block:: text
MCU_DEV=/dev/ttyUSB1
MAIN_DEV=/dev/ttyUSB0
stty -F $MCU_DEV 115200 cs8 -cstopb -parenb
stty -F $MAIN_DEV 115200 cs8 -cstopb -parenb
sb --xmodem tiboot3.bin > $MCU_DEV < $MCU_DEV
sb --ymodem sysfw.itb > $MCU_DEV < $MCU_DEV
sb --ymodem tispl.bin > $MAIN_DEV < $MAIN_DEV
sleep 1
sb --xmodem u-boot.img > $MAIN_DEV < $MAIN_DEV
