[PATCH v2 0/4] Microchip PolarFire SoC support

[Padmarao.Begari at microchip.com]

RTEMS SMP on the Microchip PolarFire Icicle Kit

Test Procedure:

1. Create the "config.ini" file with below content at rtems root 

	[riscv/mpfs64imafdc]
	BUILD_TESTS = True
	RTEMS_POSIX_API=True
	RTEMS_SMP = True
	BSP_START_COPY_FDT_FROM_U_BOOT=False
	BSP_VERBOSE_FATAL_EXTENSION = False
		
2. Build RTEMS
	$ ./waf configure --prefix=$HOME/rtems-start/rtems/6
	$ ./waf

3. Convert .exe to .elf file
	
$ riscv-rtems6-objcopy 	build/riscv/mpfs64imafdc/testsuites/smptests/sm
p01.exe
 build/riscv/mpfs64imafdc/testsuites/smptests/smp01.elf
	
4. Generate the payload for the smp01.elf using the hss-payload-
generator with hart-entry-points/exec-addr: 0x1000000000

5. Programming the'payload.bin' for the eMMC/SD
	
 5.1) Board setting and FPGA Programing
      
https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/boards/mpfs-icicle-kit-es/updating-icicle-kit/updating-icicle-kit-design-and-linux.md
			
	
 5.2). Power Cycle the Microchip PolarFire Icicle Kit and stop at the  
       HSS.
	
 5.3) type "mmc" and then "usbdmsc" on the HSS terminal(UART0).
	
 5.4) Load payload from the Host PC.
	$ sudo dd if=payload.bin of=/dev/sdb bs=512
		
 5.5) Quit USB and Reset the Icicle Kit
		
 5.6) Serial terminal UART1 displays the SMP example messages
