This file contains basic information on the port of U-Boot to IPHASE4539
(Interphase 4539 T1/E1/J1 PMC Communications Controller).
All the changes fit in the common U-Boot infrastructure, providing a new
IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539,
type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h"
file if necessary, then type "make".


Common file modifications:
--------------------------

The following common files have been modified by this project:
(starting from the ppcboot-1.1.5/ directory)

MAKEALL				- IPHASE4539 entry added
Makefile			- IPHASE4539_config entry added


New files:
----------

The following new files have been added by this project:
(starting from the ppcboot-1.1.5/ directory)

board/iphase4539/		- board-specific directory
board/iphase4539/Makefile	- board-specific makefile
board/iphase4539/config.mk	- config file
board/iphase4539/flash.c	- flash driver (for AM29LV033C)
board/iphase4539/ppcboot.lds	- linker script
board/iphase4539/iphase4539.c	- ioport and memory initialization
include/config_IPHASE4539.h	- main configuration file


New configuration options:
--------------------------

CONFIG_IPHASE4539

	Main board-specific option (should be defined for IPHASE4539).


Acceptance criteria tests:
--------------------------

The following tests have been conducted to validate the port of U-Boot
to IPHASE4539:

1. Operation on serial console:

With SMC1 defined as console in the main configuration file, the U-Boot
output appeared on the serial terminal connected to the 2.5mm stereo jack
connector as follows:

------------------------------------------------------------------------------
=> help
base    - print or set address offset
bdinfo  - print Board Info structure
bootm   - boot application image from memory
bootp   - boot image via network using BootP/TFTP protocol
bootd   - boot default, i.e., run 'bootcmd'
cmp     - memory compare
coninfo - print console devices and informations
cp      - memory copy
crc32   - checksum calculation
dcache  - enable or disable data cache
echo    - echo args to console
erase   - erase FLASH memory
flinfo  - print FLASH memory information
go      - start application at address 'addr'
help    - print online help
icache  - enable or disable instruction cache
iminfo  - print header information for application image
loadb   - load binary file over serial line (kermit mode)
loads   - load S-Record file over serial line
loop    - infinite loop on address range
md      - memory display
mm      - memory modify (auto-incrementing)
mtest   - simple RAM test
mw      - memory write (fill)
nm      - memory modify (constant address)
printenv- print environment variables
protect - enable or disable FLASH write protection
rarpboot- boot image via network using RARP/TFTP protocol
reset   - Perform RESET of the CPU
run     - run commands in an environment variable
saveenv - save environment variables to persistent storage
setenv  - set environment variables
sleep   - delay execution for some time
source  - run script from memory
tftpboot- boot image via network using TFTP protocol
	       and env variables ipaddr and serverip
version - print monitor version
?       - alias for 'help'

2. Flash driver operation

The following sequence was performed to test the "flinfo" command:

------------------------------------------------------------------------------

Note: the Hardware Configuration Word (HWC) of the 8260 is on the
first sector of the flash and should not be touched. The U-Boot
environment variables are stored on second sector and U-Boot
starts at the address 0xFFB00000.

None for the moment.


----------------------------------------------------------------------------
U-Boot and Linux for Interphase 4539 T1/E1/J1 PMC Communications Controller
----------------------------------------------------------------------------

U-Boot:

	Configure and make U-Boot:

	$ cd <path>/u-boot
	$ make IPHASE4539_config
	$ make dep
	$ make
	$ cp -p u-boot.bin /tftpboot

	Load u-boot.bin into the Flash memory at 0xffb00000.


Linux:

	Configure and make Linux:

	$ cd <patch>/linux-2.4
	$ make IPHASE4539_config
	$ make oldconfig
	$ make dep
	$ make uImage
	$ cp -p arch/powerpc/mbxboot/uImage /tftpboot

	Load uImage via tftp and boot it.


Flash organisation:

	The following preliminary layout of the Flash memory
	is defined:

	0xff800000 (   0    -   64 kB): Hardware Configuration Word.
	0xff810000 (  64 kB -  128 kB): U-Boot Environment.
	0xff820000 ( 128 kB -    3 MB): RAMdisk.
	0xffb00000 (   3 MB - 3328 kB): U-Boot.
	0xffb40000 (3328 KB -    4 MB): Linux Kernel.


For further information concerning U-Boot and Linux please consult
the "DENX U-Boot and Linux Guide".
