ppc4xx: Fix "chip_config" command for AMCC Arches

2009-08-18T07:16:33+00:00

This patch fixes the "chip_config" command for I2C bootstrap EEPROM
configuration. First it changes the I2C bootstrap EEPROM address to
0x54 as this is used on Arches (instead of 0x52 on Canyonlands/
Glacier). Additionally, the NAND bootstrap settings are removed
for Arches since Arches doesn't support NAND-booting.

ppc4xx: Fix problem with NOR range assignment in Canyonlands ft_board_setup

2009-07-28T05:26:07+00:00

This patch fixes the problem, that the current fdt board fixup code only
set's one range, the one for NOR. By this it's overwriting the already
correctly configured values done in __ft_board_setup(). Just remove this
now unneeded NOR fixup and all the ranges are correctly defined.

ppc4xx: Add some NAND-booting bootstrap entries to Kilauea chip_config cmd

2009-07-28T05:24:01+00:00

This patch adds some I2C bootstrap setting for NAND booting to the Kilauea
chip_config command ("533-nand" and "600-nand").

Additionally some incorrectly indented lines are fixed.

ppc4xx: Fix Arches DDR2 initialization

2009-07-28T05:22:46+00:00

Testing on AMCC Arches with the latest U-Boot version yielded that DDR2
initialization is currently broken. U-Boot hangs upon relocation to SDRAM
or crashes with random traps. This patch fixes this problem. Arches now
uses a different WRDTR and CLKTR default setting than Canyonlands/Glacier.

ppc4xx: Add chip_config command to AMCC Kilauea eval board

2009-07-24T07:56:40+00:00

This patch removes the "alterpll" command and replaces it with the now
ppc4xx standard "chip_config" command to configure the I2C bootstrap
EEPROM.

Add "chip_config" command for PPC4xx bootstrap configuration

2009-07-24T04:42:32+00:00

This patch adds a generic command for programming I2C bootstrap
eeproms on PPC4xx. An implementation for Canyonlands board is
included.

The command name is intentionally chosen not to be PPC4xx specific.
This way other CPU's/SoC's can implement a similar command under
the same name, perhaps with a different syntax.

Usage on Canyonlands:

=> chip_config
Available configurations (I2C address 0x52):
600-nor          - NOR  CPU: 600 PLB: 200 OPB: 100 EBC: 100
600-nand         - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100
800-nor          - NOR  CPU: 800 PLB: 200 OPB: 100 EBC: 100
800-nand         - NAND CPU: 800 PLB: 200 OPB: 100 EBC: 100
1000-nor         - NOR  CPU:1000 PLB: 200 OPB: 100 EBC: 100
1000-nand        - NAND CPU:1000 PLB: 200 OPB: 100 EBC: 100
1066-nor         - NOR  CPU:1066 PLB: 266 OPB:  88 EBC:  88 ***
1066-nand        - NAND CPU:1066 PLB: 266 OPB:  88 EBC:  88
=> chip_config 600-nor
Using configuration:
600-nor          - NOR  CPU: 600 PLB: 200 OPB: 100 EBC: 100
done (dump via 'i2c md 52 0.1 10')
Reset the board for the changes to take effect

Other 4xx boards will be migrated to use this command soon
as well.

ppc4xx: Fix FDT EBC mappings on Canyonlands

2009-07-08T08:59:06+00:00

This patch fixes 2 problems with FDT EBC mappings on Canyonlands.
First, NAND EBC mapping was missing, making Linux NAND driver
unusable on this board. Second, NOR remapping code assumed that
NOR is always on CS0, however when booting from NAND NOR is on CS3.

General help message cleanup

2009-06-12T18:47:16+00:00

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

ppc4xx: Add Sequoia RAM-booting target

2009-06-12T18:39:47+00:00

This patch adds another build target for the AMCC Sequoia PPC440EPx
eval board. This RAM-booting version is targeted for boards without
NOR FLASH (NAND booting) which need a possibility to initially
program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000)
configured to setup the SDRAM, this debugger can load this RAM-
booting image to the target address in SDRAM (in this case 0x1000000)
and start it there. Then U-Boot's standard NAND commands can be
used to program the NAND FLASH (e.g. "nand write ...").

Here the commands to load and start this image from the BDI2000:

440EPX>reset halt
440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin
440EPX>go 0x1000000

Please note that this image automatically scans for an already
initialized SDRAM TLB (detected by EPN=0). This TLB will not be
cleared. This TLB doesn't need to be TLB #0, this RAM-booting
version will detect it and preserve it. So booting via BDI2000
will work and booting with a complete different TLB init via
U-Boot works as well.
