The AM654 SoC is a lead device of the K3 Multicore SoC architecture
platform, targeted for broad market and industrial control with aim to
meet the complex processing needs of modern embedded products.
The device is partitioned into three functional domains, each containing
specific processing cores and peripherals:
Some highlights in each domain are:
- MAIN Domain:
--------------
* Quad ARMv8 A53 cores split over two clusters
* GICv3 compliant GIC500
* Configurable L3 Cache and IO-coherent architecture
* DDR Subsystem (DDRSS) with Error Correcting Code (ECC)
* Three Gigabit Industrial Communication Subsystems (ICSSG), each with dual
PRUs and dual RTUs
* Hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
* eQEP/eCAP, eHRPWM.
* Multimedia capability with CAL, DSS7-UL, SGX544, McASP
* Peripheral connectivity including USB3, PCIE, MMC/SD, GPMC, I2C, SPI,
GPIO
- MCU Domain:
-------------
* Dual lock-step capable R5F uC for safety-critical applications
* Flash subsystem with OSPI and Hyperbus interfaces
* High data throughput capable distributed DMA architecture under MCU NAVSS
* Dual ADCSS, Dual CAN-FD.
- WKUP Domain:
--------------
* Centralized System Controller for Security, Power, and Resource
management.
For further deails see AM65x Technical Reference Manual (SPRUID7, April 2018):
http://www.ti.com/lit/pdf/spruid7
This is a complex SoC and the support to add this SoC is very huge. So I
tried to split into 3 separate series:
[1/3] Adding base SoC support
[2/3] Base drivers that allow minimal boot.
[3/3] EVM support with dts and defconfig changes.
This series adds base SoC support. The rest of the two series will be a
follow up of this series.
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,
keeping safety in picture and to have faster boot time, the software boot
architecture is designed as: https://pastebin.ubuntu.com/p/NxSvDbMtSk/
Any feedback is highly appreciated.
Changes since v1:
-----------------
- Enabled OMAP_SERIAL by default for ARCH_K3
- Update SoC specific Kconfig entries so that user cannot configure them.
- Appended the kconfig symbols with SYS_K3_
- Removed #define ing the macoro inside __get_backup_bootmedia() function.
- Added/Updated SPDX tag

On K3 family SoCs, once the ROM loads image on R5, M3 resets R5 and
expects to start executing from 0x0. In order to handle this ROM
updates the boot vector of R5 such that first 64 bytes of image load
address are mapped to 0x0.
In this case, it is SPL's responsibility to jump to the proper image
location. So, update the PC with address of reset vector(like how
other exception vectors are handled), instead of branching to reset.

AM654 allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.
