2019-01-24T08:37:47Z

This patch updates copyright header in all files as follows: 1. Makes "SPDX-License-Identifier: BSD-2-Clause" as first line 2. Change copyright year to 2019 for Western Digital Signed-off-by: Anup Patel

include: Rename ipi_inject() to ipi_send() for sbi_platform

2019-01-23T03:09:26Z

For better naming, we rename ipi_inject() to ipi_send() in struct sbi_platform. We also replace term "inject" with "send" in all related places. Signed-off-by: Anup Patel

include: Drop MMIO from SBI_PLATFORM_HAS_MMIO_TIMER_VALUE

2019-01-23T03:09:26Z

It is not necessary that platform has MMIO-based timer value register. It can also have some custom (implementation specific) CSR for timer value. This patch renames SBI_PLATFORM_HAS_MMIO_TIMER_VALUE to SBI_PLATFORM_HAS_TIMER_VALUE to imply "platform timer value" instead of "mmio timer value". Signed-off-by: Anup Patel

lib: Remove target_hart and hartid parameter from TIMER callbacks

2019-01-23T03:09:26Z

The target_hart and hartid paramter of TIMER callbacks is not required because it always current hartid which can be obtained using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Remove hartid parameter from IRQCHIP callbacks

2019-01-23T03:09:26Z

The hartid parameter in IRQCHIP callbacks of sbi_platform is not required because current hartid can be determined using sbi_current_hartid() API. Signed-off-by: Anup Patel

lib: Remove source_hart and hartid parameter from IPI callbacks

2019-01-23T03:09:26Z

The source_hart and hartid parameter is really not required in IPI callbacks of sbi_platform because current hartid can always be obtained by calling sbi_current_hartid() API. Signed-off-by: Anup Patel

kendryte/k210: Add device tree support

2019-01-21T04:28:33Z

The Kendryte k210 board initial loader does not provide a device tree for the firmware and subsequent payload. Add the k210.dts device tree description file to solve this. This file describes only the SoC core components: CPUs, memory and PLIC. Automatically compile and add this file to the firmware generated using the FW_PAYLOAD_FDT_PATH configuration parameter.

kendryte/k210: Fix console

2019-01-21T04:28:33Z

Clear console input when intializing it. Signed-off-by: Damien Le Moal

build: Introduce FW_PAYLOAD_ALIGN

2019-01-21T04:28:33Z

The firmware payload offset defined by FW_PAYLOAD_OFFSET must specify a value large enough so the the payload does not overlap with the base firmware data, bss and text. For platforms without any strong requirement on the payload address, introduce the FW_PAYLOAD_ALIGN build parameter to automatically place the payload right after the base firmware at an address aligned with the defined value. Either FW_PAYLOAD_OFFSET or FW_PAYLOAD_ALIGN should be defined by a platform configuration. If both FW_PAYLOAD_OFFSET and FW_PAYLOAD_ALIGN are defined by a platform, FW_PAYLOAD_OFFSET has precedence and is used for building the final firmawre image. Using FW_PAYLOAD_ALIGN=4096 with the Kendryte platform rather than the abitrary FW_PAYLOAD_OFFSET=0x10000 value reduces the final firmware image size by about 20KB. Add a description of the FW_PAYLOAD_ALIGN configuration parameter in the fw_payload documentation file as well. And while at it, also fix various grammar and style issues in that file..

platform: Remove string functions from tinyfdt.c

2019-01-18T04:35:12Z

There are couple of string function defined in platform code. We no longer need them as we can directly link minimal libc. Every platform required to inclde this as PLIC driver required libc functions. Signed-off-by: Atish Patra
