powerpc/CoreNet: add tool to support pbl image build.
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
|
||||||
|
------------------------------------------------------------------
|
||||||
|
|
||||||
|
The CoreNet SoC's can boot directly from eSPI FLASH, SD/MMC and
|
||||||
|
NAND, etc. These SoCs use PBL to load RCW and/or pre-initialization
|
||||||
|
instructions. For more details refer section 5 Pre-boot loader
|
||||||
|
specifications of reference manual P3041RM/P4080RM/P5020RM at link:
|
||||||
|
http://www.freescale.com/webapp/search/Serp.jsp?Reference+Manuals
|
||||||
|
|
||||||
|
Building PBL Boot Image and boot steps
|
||||||
|
--------------------------------------
|
||||||
|
|
||||||
|
1. Building PBL Boot Image.
|
||||||
|
The default Image is u-boot.pbl.
|
||||||
|
|
||||||
|
For eSPI boot(available on P3041/P4080/P5020):
|
||||||
|
To build the eSPI boot image:
|
||||||
|
make <board_name>_SPIFLASH_config
|
||||||
|
make u-boot.pbl
|
||||||
|
|
||||||
|
For SD boot(available on P3041/P4080/P5020):
|
||||||
|
To build the SD boot image:
|
||||||
|
make <board_name>_SDCARD_config
|
||||||
|
make u-boot.pbl
|
||||||
|
|
||||||
|
For Nand boot(available on P3041/P5020):
|
||||||
|
To build the NAND boot image:
|
||||||
|
make <board_name>_NAND_config
|
||||||
|
make u-boot.pbl
|
||||||
|
|
||||||
|
|
||||||
|
2. pblimage support available with mkimage utility will generate Freescale PBL
|
||||||
|
boot image that can be flashed on the board eSPI flash, SD/MMC and NAND.
|
||||||
|
Following steps describe it in detail.
|
||||||
|
|
||||||
|
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.
|
||||||
|
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. Configuration files rcw.cfg and pbi.cfg must present in the
|
||||||
|
board/freescale/corenet_ds/, rcw.cfg is for RCW, pbi.cfg is for
|
||||||
|
PBI instructions. File name must not be changed since they are used
|
||||||
|
in Makefile.
|
||||||
|
2. These files can have empty lines and lines starting with "#" as first
|
||||||
|
character to put comments
|
||||||
|
|
||||||
|
Typical example of rcw.cfg file:
