[U-Boot] Adapteva Parallella support
by Martin Husemann 12 Sep '18

12 Sep '18

Hey folks, has anyone here tried to create a newer u-boot version for Adapteva Parallella boards? There is a fork that goes up to 2015.4 on github (https://github.com/parallella/parallella-uboot) ... but I'd prefer (a) a newer version and (b) something already tested - as I don't currently have the xilinc jtag cable (and not sure I could easily get one). Anyone? Martin

[U-Boot] [PATCH v2 0/5] [3/3] Initial support Texas Instrument's AM654 Platform
by Lokesh Vutla 12 Sep '18

12 Sep '18

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 0/8] [1/3] Initial support Texas Instrument's AM654 Platform
by Lokesh Vutla 12 Sep '18

12 Sep '18

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 Andreas Dannenberg (1): arm: K3: am654: Unlock control module registers during init Lokesh Vutla (7): arm: K3: Add initial support for TI's K3 generation of SoCs arm: K3: Add support for AM654 SoC definition arm: K3: Update _start instruction arm: K3: am654: Add support for boot device detection armv8: K3: am654: Add custom MMU support armv8: K3: am654: Introduce FIT generator script armv8: K3: am654: Add support for generating build targets Kconfig | 2 +- MAINTAINERS | 1 + arch/arm/Kconfig | 8 ++ arch/arm/Makefile | 1 + arch/arm/include/asm/spl.h | 2 +- arch/arm/lib/vectors.S | 8 ++ arch/arm/mach-k3/Kconfig | 50 ++++++++ arch/arm/mach-k3/Makefile | 7 ++ arch/arm/mach-k3/am6_init.c | 126 +++++++++++++++++++ arch/arm/mach-k3/arm64-mmu.c | 45 +++++++ arch/arm/mach-k3/config.mk | 19 +++ arch/arm/mach-k3/include/mach/am6_hardware.h | 44 +++++++ arch/arm/mach-k3/include/mach/am6_spl.h | 36 ++++++ arch/arm/mach-k3/include/mach/clock.h | 16 +++ arch/arm/mach-k3/include/mach/hardware.h | 12 ++ arch/arm/mach-k3/include/mach/spl.h | 12 ++ common/spl/Kconfig | 2 +- drivers/serial/Kconfig | 2 +- scripts/Makefile.spl | 9 ++ tools/k3_fit_atf.sh | 99 +++++++++++++++ 20 files changed, 497 insertions(+), 4 deletions(-) create mode 100644 arch/arm/mach-k3/Kconfig create mode 100644 arch/arm/mach-k3/Makefile create mode 100644 arch/arm/mach-k3/am6_init.c create mode 100644 arch/arm/mach-k3/arm64-mmu.c create mode 100644 arch/arm/mach-k3/config.mk create mode 100644 arch/arm/mach-k3/include/mach/am6_hardware.h create mode 100644 arch/arm/mach-k3/include/mach/am6_spl.h create mode 100644 arch/arm/mach-k3/include/mach/clock.h create mode 100644 arch/arm/mach-k3/include/mach/hardware.h create mode 100644 arch/arm/mach-k3/include/mach/spl.h create mode 100755 tools/k3_fit_atf.sh -- 2.18.0
