* Add support for the configUSE_TASK_FPU_SUPPORT in the GCC/ARM_CR5 port This is done almost identically as in the GCC/ARM_CA9 port * Adjust task stack initialitation of the GCC/ARM_CR5 port Ensure that the task stack initialization is done correctly for the different options of configUSE_TASK_FPU_SUPPORT. This is very similar to the GCC/ARM_CA9 port. The only meaningful difference is, that the FPU of the Cortex-R5 has just sixteen 64-bit floating point registers as it implements the VFPv3-D16 architecture. You may also refer to the ARM documentation * Add support for FPU safe interrupts to the GCC/ARM_CR5 port Similar to GCC/ARM_CA9 port * Clarify comment about the size of the FPU registers of Cortex R5
Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
