From bb671baa20f7ae9a17e20528d56527da1072ee57 Mon Sep 17 00:00:00 2001 From: yuhzheng Date: Thu, 30 Jan 2020 19:45:03 +0000 Subject: [PATCH] Removing unnecessary ThirdParty ports -- Wiced_CY and nrf52840-dk. For projects depending on either of these two ports, please update your projects according to below: Wiced_CY -- Use GCC/ARM_CRx_No_GIC instead. nrf52840-dk -- Use GCC/ARM_CM7/r0p1 instead. Please note that, kernel port shall only take dependency on MCU core, not MCU peripherals. (Please take out RTC related from kernel port.) For low power feature (tickless) in FreeRTOS, please follow this page https://www.freertos.org/low-power-ARM-cortex-rtos.html. In case ARM_CM7/rop1 is missing any feature, reach out to us. git-svn-id: https://svn.code.sf.net/p/freertos/code/trunk@2812 1d2547de-c912-0410-9cb9-b8ca96c0e9e2 --- .../portable/ThirdParty/GCC/Wiced_CY/port.c | 324 ---------------- .../ThirdParty/GCC/Wiced_CY/portASM.S | 268 ------------- .../ThirdParty/GCC/Wiced_CY/portmacro.h | 179 --------- .../ThirdParty/GCC/nrf52840-dk/port.c | 148 -------- .../ThirdParty/GCC/nrf52840-dk/port_cmsis.c | 357 ------------------ .../GCC/nrf52840-dk/port_cmsis_systick.c | 299 --------------- .../ThirdParty/GCC/nrf52840-dk/portmacro.h | 36 -- .../GCC/nrf52840-dk/portmacro_cmsis.h | 187 --------- 8 files changed, 1798 deletions(-) delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/port.c delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/portASM.S delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/portmacro.h delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/nrf52840-dk/port.c delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/nrf52840-dk/port_cmsis.c delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/nrf52840-dk/port_cmsis_systick.c delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/nrf52840-dk/portmacro.h delete mode 100644 FreeRTOS/Source/portable/ThirdParty/GCC/nrf52840-dk/portmacro_cmsis.h diff --git a/FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/port.c b/FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/port.c deleted file mode 100644 index d3989aca2..000000000 --- a/FreeRTOS/Source/portable/ThirdParty/GCC/Wiced_CY/port.c +++ /dev/null @@ -1,324 +0,0 @@ -/* - * FreeRTOS Kernel V10.2.0 - * Copyright (C) 2017 Amazon.com, Inc. or its affiliates.
