powerpc/corenet_ds: Update README and README.srio-pcie-boot-corenet

Added descriptions about boot from PCIE in the files README and
doc/README.srio-pcie-boot-corenet, and changed the name of the
doc/README.srio-boot-corenet to doc/README.srio-pcie-boot-corenet.

-SRIO Boot on Corenet Platforms
-------------------------------
-
-For some PowerPC processors with SRIO interface, boot location can be configured
-to SRIO by RCW. The processor booting from SRIO can do without flash for u-boot
-image, ucode and ENV. All the images can be fetched from another processor's
-memory space by SRIO link connected between them.
-
-This document describes the processes based on an example implemented on P4080DS
-platforms and a RCW example with boot from SRIO configuration.
-
-Environment of the SRIO boot:
-	a) Master and slave can be SOCs in one board or SOCs in separate boards.
-	b) They are connected with SRIO links, whether 1x or 4x, and directly or
-	   through switch system.
-	c) Only Master has NorFlash for booting, and all the Master's and Slave's
-	   U-Boot images, UCodes will be stored in this flash.
-	d) Slave has its own EEPROM for RCW and PBI.
-	e) Slave's RCW should configure the SerDes for SRIO boot port, set the boot
-	   location to SRIO, and holdoff all the cores.

-		d) Restart up master and it will boot up normally from its NorFlash.

-		f) Master will set an inbound SRIO window covered slave's UCode and ENV
-		   stored in master's NorFlash.
-		g) Master will set outbound SRIO windows in order to configure slave's
-		   registers for the core's releasing.
-		h) Since all cores of slave in holdoff, slave should be powered on before all
-		   the above master's steps, and wait to be released by master. In the
-		   startup phase of the slave from SRIO, it will finish some necessary
-		   configurations.
-		i) Slave will set a specific TLB entry for the boot process.
-		j) Slave will set a LAW entry with the TargetID SRIO port 1 for the boot.
-		k) Slave will set a specific TLB entry in order to fetch UCode and ENV
-		   from master.
-		l) Slave will set a LAW entry with the TargetID SRIO port 1 for UCode and ENV.
-
-How to use this feature:
-	To use this feature, you need to focus those points.
-
-	1. Slave's RCW with SRIO boot configurations, and all cores in holdoff
-	   configurations.
-	   Please refer to the examples given above.
-
-	2. U-Boot image's compilation.
-		For master, U-Boot image should be generated normally.
-
-		For example, master U-Boot image used on P4080DS should be compiled with
-
-				make P4080DS_config.
-
-		For slave, U-Boot image should be generated specifically by
-
-				make xxxx_SRIOBOOT_SLAVE_config.
-
-		For example, slave U-Boot image used on P4080DS should be compiled with
-
-				make P4080DS_SRIOBOOT_SLAVE_config.
-
-	3. Necessary modifications based on a specific environment.
-		For a specific environment, the addresses of the slave's U-Boot image,
-		UCode, ENV stored in master's NorFlash, and any other configurations
-		can be modified in the file:
-					include/configs/corenet_ds.h.
-
-	4. Set and save the environment variable "bootmaster" with "SRIO1" or "SRIO2"
-	   for master, and then restart it in order to perform the role as a master
-	   for boot from SRIO.
