Add support for using initrd provided by the bootloader as the RAM Disk. Location of the initrd is specified by the DISK_RAM_START Kconfig option. Currently only uncompressed filesystem images are supported. Signed-off-by: Mykyta Poturai <mykyta_poturai@epam.com>
Add lz4frame and xxhash to the build system. This is required to support the decompression of LZ4 files made with LZ4 cli tool. Base lz4 library only supports decompression of raw LZ4 blocks without taking into account the frame metadata. Signed-off-by: Mykyta Poturai <mykyta_poturai@epam.com>

Add support for decompressing the initrd before using it as the RAM Disk. For now, only LZ4 compression is supported. It is advised to use smaller block sizes for the compressed initrd to reduce the size of heap memory required for decompression. Signed-off-by: Mykyta Poturai <mykyta_poturai@epam.com>
