Summary:
========
This directory contains the source code for PPCBoot, a monitor for
Embedded PowerPC boards, which can be installed in a boot ROM and
used to test the hardware or download and run application code.
The development of PPCBoot is closely related to Linux: some parts of
the source code originate in the Linux source tree, we still have
some header files in common, and special provision has been made to
support booting of Linux images.
Some attention has been paid to make this software easily
configurable and extendable. For instance, all monitor commands are
implemented with the same call interface, so that it's very easy to
add new commands. Also, instead of permanently adding rarely used
code (for instance hardware test utilities) to the monitor, you can
load and run it dynamically.
Status:
=======
In general, all boards for which a configuration option exists in the
Makefile have been tested to some extent and can be considered
"working". In fact, many of them are used in production systems.
In case of problems see the CHANGELOG and CREDITS files to find out
who contributed the specific port.
Exception from this rule: the port to the Sandpoint 8240 has not been
completed yet.
Where to get help:
==================
In case you have questions about, problems with or contributions for
PPCBoot you should send a message to the PPCBoot mailing list at
. There is also an archive of
previous traffic on the mailing list - please search the archive

Software Configuration:
=======================
Configuration is usually done using C preprocessor defines; the
rationale behind that is to avoid dead code whenever possible.
There are two classes of configuration variables:
* Configuration _OPTIONS_:
These are selectable by the user and have names beginning with
"CONFIG_".
* Configuration _SETTINGS_:
These depend on the hardware etc. and should not be meddled with if
you don't know what you're doing; they have names beginning with
"CFG_".
Later we will add a configuration tool - probably similar to or even
identical to what's used for the Linux kernel. Right now, we have to
do the configuration by hand, which means creating some symbolic
links and editing some configuration files. We use the TQM8xxL boards
as an example here.
Selection of Processor Architecture and Board Type:
---------------------------------------------------
For all supported boards there are ready-to-use default
configurations available; just type "make _config".
Example: For a TQM823L module type:
cd ppcboot
make TQM823L_config
For the Cogent platform, you need to specify the cpu type as well;
e.g. "make cogent_mpc8xx_config". And also configure the cogent
directory according to the instructions in cogent/README.
Configuration Options:
----------------------
Configuration depends on the combination of board and CPU type; all
such information is kept in a configuration file
"include/configs/.h".
Example: For a TQM823L module, all configuration settings are in
"include/configs/TQM823L.h".
The following options need to be configured:
- CPU Type: Define exactly one of

CONFIG_IMPA7, CONFIG_LART, CONFIG_LUBBOCK,
CONFIG_SHANNON, CONFIG_SMDK2400, CONFIG_SMDK2410,
CONFIG_TRAB
- CPU Module Type: (if CONFIG_COGENT is defined)
Define exactly one of
CONFIG_CMA286_60_OLD
--- FIXME --- not tested yet:
CONFIG_CMA286_60, CONFIG_CMA286_21, CONFIG_CMA286_60P,
CONFIG_CMA287_23, CONFIG_CMA287_50
- Motherboard Type: (if CONFIG_COGENT is defined)
Define exactly one of
CONFIG_CMA101, CONFIG_CMA102
- Motherboard I/O Modules: (if CONFIG_COGENT is defined)
Define one or more of
CONFIG_CMA302
- Motherboard Options: (if CONFIG_CMA101 or CONFIG_CMA102 are defined)
Define one or more of
CONFIG_LCD_HEARTBEAT - update a character position on
the lcd display every second with
a "rotator" |\-/|\-/
- MPC824X Family Member (if CONFIG_MPC824X is defined)
Define exactly one of
CONFIG_MPC8240, CONFIG_MPC8245
- 8xx CPU Options: (if using an 8xx cpu)
Define one or more of
CONFIG_8xx_GCLK_FREQ - if get_gclk_freq() can not work e.g.
no 32KHz reference PIT/RTC clock
- Clock Interface:
CONFIG_CLOCKS_IN_MHZ
PPCBoot stores all clock information in Hz
internally. For binary compatibility with older Linux
kernels (which expect the clocks passed in the
bd_info data to be in MHz) the environment variable
"clocks_in_mhz" can be defined so that PPCBoot
converts clock data to MHZ before passing it to the
Linux kernel.
When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
"clocks_in_mhz=1" is automatically included in the
default environment.
- Console Interface:
Depending on board, define exactly one serial port
(like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
CONFIG_8xx_CONS_SCC1, ...), or switch off the serial
console by defining CONFIG_8xx_CONS_NONE
Note: if CONFIG_8xx_CONS_NONE is defined, the serial
port routines must be defined elsewhere
(i.e. serial_init(), serial_getc(), ...)
CONFIG_CFB_CONSOLE
Enables console device for a color framebuffer. Needs following
defines (cf. smiLynxEM, i8042, board/eltec/bab7xx)
VIDEO_FB_LITTLE_ENDIAN graphic memory organisation
(default big endian)
VIDEO_HW_RECTFILL graphic chip supports
rectangle fill
(cf. smiLynxEM)
VIDEO_HW_BITBLT graphic chip supports
bit-blit (cf. smiLynxEM)
VIDEO_VISIBLE_COLS visible pixel columns
(cols=pitch)
VIDEO_VISIBLE_ROWS visible pixel rows
VIDEO_PIXEL_SIZE bytes per pixel
VIDEO_DATA_FORMAT graphic data format
(0-5, cf. cfb_console.c)
VIDEO_FB_ADRS framebuffer address
VIDEO_KBD_INIT_FCT keyboard int fct
(i.e. i8042_kbd_init())
VIDEO_TSTC_FCT test char fct
(i.e. i8042_tstc)
VIDEO_GETC_FCT get char fct
(i.e. i8042_getc)
CONFIG_CONSOLE_CURSOR cursor drawing on/off
(requires blink timer
cf. i8042.c)
CFG_CONSOLE_BLINK_COUNT blink interval (cf. i8042.c)
CONFIG_CONSOLE_TIME display time/date info in
upper right corner
(requires CFG_CMD_DATE)
CONFIG_VIDEO_LOGO display Linux logo in
upper left corner
CONFIG_CONSOLE_EXTRA_INFO
addional board info beside
the logo
When CONFIG_CFB_CONSOLE is defined, video console is
default i/o. Serial console can be forced with
environment 'console=serial'.
- Console Baudrate:
CONFIG_BAUDRATE - in bps
Select one of the baudrates listed in
CFG_BAUDRATE_TABLE, see below.
- Interrupt driven serial port input:
CONFIG_SERIAL_SOFTWARE_FIFO
PPC405GP only.
Use an interrupt handler for receiving data on the
serial port. It also enables using hardware handshake
(RTS/CTS) and UART's built-in FIFO. Set the number of
bytes the interrupt driven input buffer should have.
Set to 0 to disable this feature (this is the default).
This will also disable hardware handshake.
- Boot Delay: CONFIG_BOOTDELAY - in seconds
Delay before automatically booting the default image;
set to -1 to disable autoboot.
See doc/README.autoboot for these options that
work with CONFIG_BOOTDELAY. None are required.
CONFIG_BOOT_RETRY_TIME
CONFIG_BOOT_RETRY_MIN
CONFIG_AUTOBOOT_KEYED
CONFIG_AUTOBOOT_PROMPT
CONFIG_AUTOBOOT_DELAY_STR
CONFIG_AUTOBOOT_STOP_STR
CONFIG_AUTOBOOT_DELAY_STR2
CONFIG_AUTOBOOT_STOP_STR2
CONFIG_ZERO_BOOTDELAY_CHECK
CONFIG_RESET_TO_RETRY
- Autoboot Command:
CONFIG_BOOTCOMMAND
Only needed when CONFIG_BOOTDELAY is enabled;
define a command string that is automatically executed
when no character is read on the console interface
within "Boot Delay" after reset.
CONFIG_BOOTARGS
This can be used to pass arguments to the bootm
command. The value of CONFIG_BOOTARGS goes into the
environment value "bootargs".
CONFIG_RAMBOOT and CONFIG_NFSBOOT
The value of these goes into the environment as
"ramboot" and "nfsboot" respectively, and can be used
as a convenience, when switching between booting from
ram and nfs.
- Pre-Boot Commands:
CONFIG_PREBOOT
When this option is #defined, the existence of the
environment variable "preboot" will be checked
immediately before starting the CONFIG_BOOTDELAY
countdown and/or running the auto-boot command resp.
entering interactive mode.
This feature is especially useful when "preboot" is
automatically generated or modified. For an example
see the LWMON board specific code: here "preboot" is
modified when the user holds down a certain
combination of keys on the (special) keyboard when
booting the systems
- Serial Download Echo Mode:
CONFIG_LOADS_ECHO
If defined to 1, all characters received during a
serial download (using the "loads" command) are
echoed back. This might be needed by some terminal
emulations (like "cu"), but may as well just take
time on others. This setting #define's the initial
value of the "loads_echo" environment variable.
- Kgdb Serial Baudrate: (if CFG_CMD_KGDB is defined)
CONFIG_KGDB_BAUDRATE
Select one of the baudrates listed in
CFG_BAUDRATE_TABLE, see below.
- Monitor Functions:
CONFIG_COMMANDS
Most monitor functions can be selected (or
de-selected) by adjusting the definition of
CONFIG_COMMANDS; to select individual functions,
#define CONFIG_COMMANDS by "OR"ing any of the
following values:
#define enables commands:
