It checks the size of available memory and performs a simple, fast and non-destuctive memory test on the way.
NAK. Please use proper I/O accessors.

Right.
In which case, why are not these used when writing config values to DDR registers (for instance) even in some very recently added boards, such as p2020ds?
Because this escaped review?

These were produced by grep -nr ddr-> board/ | grep -v out_be
I can attach a listing, but it should be quicker this way. Up until now it seemed a rather common practice to initialize ddr controllers directly, bypassing io accessors.

I don't have an plans to fix this, however we can add it to the TODO list. Just isn't high priority at this point.
- k
+CONFIG_SYS_TEXT_BASE = 0xfffc0800 +LDFLAGS +=
--section-start=.ppcenv=$(CONFIG_ENV_ADDR)
Please mode defines to board config file and get rid of config.mk
And another question: how am I supposed to specify linker flags in the board config file (I suppose, you mean boards.cfg). There's no examples throughout the u-boot tree where it is done and Makefile do not seem to peek those either (they just end up in autoconf.mk).

No, I mean include/configs/<name>.h

Anyway - maybe you should ponder why you need to do something nobody else needs, and then fix the code.

Mpq101 is a RapidIO development board in AMC form factor, featuring MPC8548 processor, 512MB of hardwired DDR2 RAM, 128MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled.
Additional board information is available at: http://www.mc.com/products/boards/ensemble_mpq101_rapidio_powerquicc_iii.asp...
Environment is configured to preceed the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling).

Mpq101 is a RapidIO development board in AMC form factor, featuring MPC8548 processor, 512MB of hardwired DDR2 RAM, 128MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled.
Additional board information is available at: http://www.mc.com/products/boards/ensemble_mpq101_rapidio_powerquicc_iii.asp...
Environment is configured to preceed the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling).

I'm not going to review this again. Why don't you explain what was changed compared to the previous version? Please see the second bullet at http://www.denx.de/wiki/view/U-Boot/Patches#Sending_updated_patch_versions for a detailed explanation.
And you still have a board/mercury/mpq101/config.mk even though I asked you to get rid of it.
Please also run your patch through checkpatch.pl, remove C++ comments, remove deads code, do not #undef variables that are not #defined, use TAB for vertical alignment and fix other Coding Style issues.
Best regards,
Wolfgang Denk
And you still have a board/mercury/mpq101/config.mk even though I asked you to get rid of it.
1. I want to fit an environment and the bootloader into a single flash sector. 2. Environment must be on the sector boundary, otherwise saveenv won't rewrite it. 3. If I don't fix up the ppcenv starting address, the resulting u-boot image will shrink by the environment size and won't start on sector boundary itself. 4. Other boards use handcrafted ld scripts to fit environments at right boundaries.
That's why I need the LDFLAGS in question. If not in config.mk, where am I supposed to put them? Custom ld script is definitely an overshoot in this and other similar cases.

This is a very bad idea as it will open a window brick your system at each and every "saveenv" command.
I strongly recommend not to do that.

If you stop doing 1., all other problems will just disappear.

If you really insist in such an unreliablke configuration, a custom linker script would IMO be better, as it would make the image layout more visible.

This issue is well understood. Yet, we are talking an industrial mezzanine card here, of variety which is put into the (ups-backed in most cases) rack once and forgotten.
If it was a consumer or developer oriented device, I, of course, would use a safer approach. From what I've seen, this is more or less in line with many other boards already supported by u-boot.
If you stop doing 1., all other problems will just disappear.
Unfortunately, these boards have flash chips without small boot blocks, and considering the nature of typical board usage (as described) vs value of some additional flash space, I see it as a reasonable trade-off.
If you really insist in such an unreliablke configuration, a custom linker script would IMO be better, as it would make the image layout more visible.
Typical ld script is rather largish with many details of no direct relevance to any specific board. Single flag modifying the section offset has the advantage of being concise and immediately visible.
I will, of course, look at it again.

Can you update this against the u-boot-mpc85xx.git and use the new common SRIO init code
I assume customer linker script is because of where you have the environment. If so might be useful to add that to the commit comment.

I assume customer linker script is because of where you have the environment. If so might be useful to add that to the commit comment.
I was under impression that commit message and comment in the linker script make it rather clear.

1.7.3.2
Mpq101 is a RapidIO development board in AMC form factor, featuring MPC8548 processor, 512MB of hardwired DDR2 RAM, 128MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled.
Additional board information is available at: http://www.mc.com/products/boards/ensemble_mpq101_rapidio_powerquicc_iii.asp...
Environment is configured to precede the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling). This is achieved by means of custom ld script.
Signed-off-by: Alex Dubov oakad@yahoo.com --- Changes for v6: - Remove "1"s from feature defines and fix a SRIO ifdef in tlb.c Changes for v5: - Use new common SRIO configuration definitions. - Replace initdram() with platform required fixed_sdram(). - Don't use get_ram_size() in fixed_sdram() as TLBs are set after it exits by common platform code. Changes for v4: - Replace config.mk supplied linker flags with custom linker script. - Fix checkpatch errors. Changes for v3: - Use io accessor functions for all mmio accesses. - Add configuration options for RTC and EEPROM on I2C buses. Changes for v2: - Remove some stale configuration code from board initialization functions.

You might also want to set:

to match BOOTMAPSZ.
Sorry, I keep nit picking ;)

Can you, please, assure me, that when this particular line is corrected the patch will be accepted? If not, what possible additional problems do you see there?
Mpq101 is a RapidIO development board in AMC form factor, featuring MPC8548 processor, 512MB of hardwired DDR2 RAM, 128MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled.
Additional board information is available at: http://www.mc.com/products/boards/ensemble_mpq101_rapidio_powerquicc_iii.asp...
Environment is configured to precede the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling). This is achieved by means of custom ld script.
Signed-off-by: Alex Dubov oakad@yahoo.com --- Cahnges for v7: - Add CONFIG_SYS_BOOTM_LEN define Changes for v6: - Remove "1"s from feature defines and fix a SRIO ifdef in tlb.c Changes for v5: - Use new common SRIO configuration definitions. - Replace initdram() with platform required fixed_sdram(). - Don't use get_ram_size() in fixed_sdram() as TLBs are set after it exits by common platform code. Changes for v4: - Replace config.mk supplied linker flags with custom linker script. - Fix checkpatch errors. Changes for v3: - Use io accessor functions for all mmio accesses. - Add configuration options for RTC and EEPROM on I2C buses. Changes for v2: - Remove some stale configuration code from board initialization functions.

Environment is configured to precede the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling). This is achieved by means of custom ld script.

Cahnges for v7:
- Add CONFIG_SYS_BOOTM_LEN define
Changes for v6:
- Remove "1"s from feature defines and fix a SRIO ifdef in tlb.c
Changes for v5:
- Use new common SRIO configuration definitions.
- Replace initdram() with platform required fixed_sdram().
- Don't use get_ram_size() in fixed_sdram() as TLBs are set after it exits by common platform code.
Changes for v4:
- Replace config.mk supplied linker flags with custom linker script.
- Fix checkpatch errors.
Changes for v3:
- Use io accessor functions for all mmio accesses.
- Add configuration options for RTC and EEPROM on I2C buses.
Changes for v2:
- Remove some stale configuration code from board initialization functions.

Environment is configured to precede the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling). This is achieved by means of custom ld script.
Signed-off-by: Alex Dubov oakad@yahoo.com
Changes for v8:
- Move CONFIG_SYS_LDSCRIPT to board config file
- Explicitly refer to env_embedded.o in ld script, as this object is no longer linked into libcommon.o
Changes for v7:
- Add CONFIG_SYS_BOOTM_LEN define
Changes for v6:
- Remove "1"s from feature defines and fix a SRIO ifdef in tlb.c
Changes for v5:
- Use new common SRIO configuration definitions.
- Replace initdram() with platform required fixed_sdram().
- Don't use get_ram_size() in fixed_sdram() as TLBs are set after it exits by common platform code.
Changes for v4:
- Replace config.mk supplied linker flags with custom linker script.
- Fix checkpatch errors.
Changes for v3:
- Use io accessor functions for all mmio accesses.
- Add configuration options for RTC and EEPROM on I2C buses.
Changes for v2:
- Remove some stale configuration code from board initialization functions.

Please keep the boards.cfg clean from configuration settings. Move the definition of CONFIG_SYS_LDSCRIPT into your board config header file.
[Kumar also reported that this does not even build. I confirm this.]
Best regards,

That's because of the relatively recent change to how the env_embedded.o is treated by the build system, so I need to refer to it explicitly, rather then by wildcard.
Shall I send a whole patch again or incremental fix will do?
