Provides a tool to build boot Image for PBL(Pre boot loader) which is
used on Freescale CoreNet SoCs, PBL can be used to load some instructions
and/or data for pre-initialization. The default output image is u-boot.pbl,
for more details please refer to doc/README.pblimage.

+Freescale PBL(pre-boot loader) Boot Image generation using mkimage
+------------------------------------------------------------------
+
+This document describes the U-Boot feature as it
+is implemented for the Freescale CoreNet SoC.
+
+The CoreNet SoC's can boot directly from eSPI FLASH, SD/MMC.
+
+for more details refer section 5 Pre-boot loader specifications.
+
+Building PBL Boot Image and boot steps
+--------------------------------------
+
+1. Building PBL Boot Image.
+ The default Image is u-boot.pbl. Before build the iamge, make sure
+ rcw data in pblimage.cfg is suitable for the platform, if not, this
+ need to be fixed in step 2.
+
+ For eSPI boot:
+ To build the eSPI boot image for P4080DS:
+ make P4080DS_SPIFLASH
+
+ To build the eSPI boot image for P3041DS:
+ make P3041DS_SPIFLASH
+
+ To build the eSPI boot image for P5020DS:
+ make P5020DS_SPIFLASH
+
+ For SD boot:
+ To build the SD boot image for P4080DS:
+ make P4080DS_SDCARD
+
+ To build the SD boot image for P3041DS:
+ make P3041DS_SDCARD
+
+ To build the SD boot image for P5020DS:
+ make P5020DS_SDCARD
+
+ For Nand boot(P4080DS does not have Nand chip):
+ To build the PBL boot image for P3041DS:
+ make P3041DS_NAND
+
+ To build the PBL boot image for P5020DS:
+ make P5020DS_NAND
+
+
+2. Command below provided a way to re-build the PBL boot image if the
+configuration file needes to be modified while the u-boot.bin does not
+need to be re-build.
+
+Command syntax:
+--------------
+./tools/mkimage -n <board specific configuration file> \
+ -T pblimage -d <input_raw_binary> <output_pblboot_file>
+
+for ex.
+./tools/mkimage -n ./board/freescale/corenet_ds/pblimage.cfg \
+ -T pblimage -d u-boot.bin u-boot.pbl
+
+
+3. pblimage support available with mkimage utility will generate Freescale PBL
+boot image that can be flashed on the board eSPI flash, SD/MMC. Following steps
+described how to boot from eSPI flash, SD/MMC.
+
+ 1). Boot from eSPI flash
+ Write u-boot.pbl to eSPI flash from offset 0x0.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>sf probe 0
+ =>sf erase 0 100000
+ =>sf write 100000 0 $filesize
+ Change SW1[1:5] = off off on off on.
+
+ 2). Boot from SD/MMC
+ Write u-boot.pbl to SD/MMC from offset 0x1000.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>mmcinfo
+ =>mmc write 100000 8 441
+ Change SW1[1:5] = off off on on off.
+
+ 3). Boot from Nand
+ Write u-boot.pbl to Nand from offset 0x0, Note that in case of eLBC NAND
+ flash, the address starts from the first good block.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>nand info
+ =>nand erase 0 100000
+ =>nand write 100000 0 $filesize
+ Change SW1[1:5] = off on off off on
+ Change SW7[1:4] = on off off on
+
+Board specific configuration file specifications:
+------------------------------------------------
+1. This file must present in the $(BOARDDIR) and the name should be
+ pblimage.cfg (since this is used in Makefile)
+2. This file can have empty lines and lines starting with "#" as first
+ character to put comments
+
+Typical example of pblimage.cfg file:
+-----------------------------------
+
+#PBL preamble and RCW header
+aa55aa55 010e0100
+#64 bytes RCW data for P4080DS, replace it when building image
+#for P3041DS or P5020DS
