Do none of the boards have disks? At least openrd-base should have IDE 
(and openrd-client as well if the patch to introduced it is finally merged).

So IDE should stay IMO, but the IDE stuff should be split into 
board-specifics (basically the defines for the IDE0 and, if it exists, 
IDE1 base addresses) and SoC-specifics (basically everything else, i.e. 
all that is required for cmd_ide.c to compile).

Amicalement,

This is only OK, if the memory banks are consecutive without
gaps ... is this true for all boards?

I setup the initial stack in the SDRAM, because I didn;t know,
if there is on this cpu family a better place for the initial stack.
(Some cpu internal ram?)

Do you know, if we have something like this on this cpu family?

Thanks, I really appreciate this patch, but I have a minor request for
change:

When you touch this board now and make it work with
CONFIG_SYS_ARM_WITHOUT_RELOC not defined, we should also drop all
references to CONFIG_SYS_ARM_WITHOUT_RELOC from the code to make it
obvious that this board has been adapted.

Thanks.

Is this really needed?  As far as I can see CONFIG_RELOC_FIXUP_WORKS
is not defined anywhere in any ARM related fiole, so there shouldbe no
need to undef it.

This is wrong. You must not use RAM for the initial stack, or it
cannot be initialized / tested as it should be.  If you hav eno static
RAM or other on-chip memory that could be used, you might try and lock
(some part of) the data cache and use this as storage for the initial
global data and stack.

As mentioned before: if ther eios no SRAM or other on-chip memory, we
can lock the data cache, or parts of it.  This has been done on other
boards before.

I think Marek has patches in his queue that implement this for PXA, so
maybe these may be interesting for other ARM families as well.

Marek, maybe you can post your stuff, even if preliminary?  Thanks.

[U-Boot] [PATCH] Kirkwood: dram_init is moved to dram.c

[Prafulla Wadaskar]

For all Kirkwood boards so far dram_init function is duplicated
dram_init function is moved to dram.c and relevant code from all
board specific files removed

If any board needs specific dram init handling than standard one,
then, a macro CONFIG_SYS_BOARD_DRAM_INIT should be defined in
board config header file and the dram_init function can be put
in board specific source file
For ex. keymile boards

[U-Boot] [PATCH] kirkwood: added common config file mv-config.h

[Prafulla Wadaskar]

It is observed that, in most of the board configs the code is being
duplicated, also for any common change all board files needs update
This issue was under discussion from long on mailing list and we
converge on introducing common config file.

With this patch-
1. Total Kirkwood specific configuration code is reduced by 210 lines
2. All common configuration can be shared by multiple boards
3. Easy to manage common updates like ARM relocation changes

mv-config.h file is added to include/configs/
It contains all common configuration supported for all Kirkwood boards
The respective board configs are updated for its usage

Build tested for guruplug, mv88f6281gtw_ge, openrd_base,
rd6281a and sheevaplug
Binary execution tested for sheevaplug

Todo:
1. Other custom Kirkwood boards to be synced
2. After ARM relocation patches mvgbe driver is broken for network
activity (need to be addressed)
3. The support to be extended for Orion5X based boards

Yes, those are consecutive without gaps on all boards so far.
But one can configure with gaps too, for ex. If any new board uses two chips with smaller size then it is possibility of gap insertion.

In that case how it should be?

At this moment I only see the case with edminiv2 board where ATA bus0 is configured for sata port1.
To extend this support for this board, we can undef and redef the respective macros.

Whereas on all other boards it is one-to-one mapping.

To me setting default configuration make more sense, that avoids code duplication in several files.

Good question ... for this case we must adapt in arch/arm/lib/board.c

addr = CONFIG_SYS_SDRAM_BASE + gd->ram_size;

But no idea, where to put u-boot ... at the end of the first
bank? at the end of the last bank?

I guess the most correct approach would be to "lump" together all banks 
until one is found not to be contiguous. The "lump" would be "the RAM".
Technically, if the banks are not in ascending base address order then 
you'd have to sort them out, so the best is to make it a requirement 
that they are in ascending base address order.

Even if almost all boards have straight rather than cross mappings of 
IDE0/IDE1 to SATA0/SATA1, not all of them have two busses (guruplug has 
only one, and likewise another kirkwood based board I'm working on) so 
half the boards would have to modify the settings anyway.

Besides, having each board explicitely telling what busses is has rather 
than making it half implicit in the SoC common config file has two 
advantages:

- someone looking at the board config file will immediately know without 
if it supports IDE *and* how many busses it actually provides *and* how 
they are mapped;

- boards will always declare "what is there" rather than declaring 
either "what is there" or possibly "what isn't there even though the 
common config said there would be".

After all, this is only one or two lines in the board config, and they 
are always positively informative.

Well one can always undef if using only one sataport, as we undef commands configured in config_cmd_default.h
On the other hand one can say I will define the needed config for used sata port. This makes more sense

I do agree, it is positively informative,
I will keep sata port config out of the common definition.

Yes, Kirkwood do have internal SRAM of 2kB size called Security SRAM
I have never used it before, I will give a try to use it. Otherwise using a data cache will be other option

I will remove this dependency

If possible, the memory controller should be configured such that the
banks are mapped at different addresses then, so that they again form
a contiguous RAM area.

If this is not possible (because the bank base addresses cannot be
adjusted), then we have a problem.

It seems logical to me to put U-Boot to the end of the bank with the
highest address.

But as mentioned before, this may be not a nice system to use. So far
we kind of assume to have a contiguous area of RAM usable.
