General comment: There are lots of coding style issues: trailing
white space, incorrect brace style, lines too long, C++ comments,
incorrect indentation, indentation not by TAB, etc.
Please clean up.

Please do not use offset lists, but define a proper C data structure
instead. And never ever access device regiters through simple
volatile pointers. Use proper accessor functions. Here and elsewhere.
The whole code needs a *major* cleanup before resubmitting.
[Note: I do not spend time on the second part this time.]

Hi,
All examples I checked use the same syntax for defining registers, so I left it
in the code. If that is a problem, can you indicate an example which does The Right Thing (tm)?

I think the patch now matches the other criteria. The patch is a bit bigger, since
other code did not follow the Coding Styles either. I used indent to fix my code and it fixed the other code as well.
The second patch will follow when this patch is OK.
Regards,
Remco Poelstra

NAK. When you have to #unifdef existing variable definitions, then
ther eis something fundamentally wrong. Please fix this problem at the
cause, i. e. where the wroing values are defined.

Is there no way to combine this code with the one for the LPC2292? It
doesn't look that different to me...

Again: Is there no way to combine this code with the one for the
LPC2292? It doesn't look that different to me...

The problem is that start.S needs hardware.h, but the code in immap.h
should not be included in start.S, so I can not merge hardware.h and immap.h

Interesting point. I was wondering the same. The problem lies in the
fact that you want this patch to use C data structures, while the
LPC2292 code uses offset lists. I can not convert the LPC2292 code to C
structures, since a) I can not test the code b) I get paid to design
hardware, not getting my ports published. I'm doing this to give
something back to the community, since I really appreciate the work done
by other OSS developers. But I can not spend time on converting complete
other architectures. I leave that to other (the original LPC2292?)
developers.

No, thumb code is less efficient in terms of performance, but this
single file needs thumb code. See LPC2292.

I don't need it, but start.S wants to include it. See my comment about
the #ifdef's. Other architectures left it empty too, so it seemed the
best option to me.

Yes I do. They are straight from the LPC2292 code, so once they were
considered OK. I checked out the the write{s,l,b} functions in asm/io.h,
but although they look similar, for some reason they simply don't work.
Given the similarities between the write{s,l,b} and the PUT* functions,
what is the problem with those? Furthermore, the ARM architecture
doesn't use any kind of special instructions for accessing registers,
everything is memory mapped.
I do understand that you want the best code for U-boot, but I do not
entirely agree on all points. Certainly when I look at the code already
in place in U-boot.
Please tell me what you really want to see changed/whether you expect me
to convert the LPC2292 code.
Depending on the amount of work left I'll reconsider submitting a patch.
Kind regards,
Remco Poelstra

Why not? I'm not aware of such a restriction?

I would like to avoid the ever growing list of
#if defined(this) || defined(that) || defined(...) || ...
Maybe we can have a common #define that covers the common case?

Hm... that doesn't really make sense to me. Also, the error checking
in this file makes little sense to me.

I'm not an expert for this processor, but I wonder it there might be
some form of sync instruction (or memory barrier or similar) needed?

I'm not an expert in assembly, but at first I had immap.h included in
start.S and it complained about invalid instructions, so if I combine
hardware.h and immap.h, then there must be some way of making sure that
the assembler ignores the C code in immap.h. Do you know of any such thing?

I could add something like
#if defined(CONFIG_LPC2922) || defined(CONFIG_LPC2468)
#define (CONFIG_LPC2000)
#endif
in a general place and then use CONFIG_LPC2000 at the common places.
The problem I then have is: What would be the best place to put such
define? Preferably it is automatically included also for the LPC2292
code. If that's not possible, it can be defined in the board config, but
I think that leads to confusion.
What's your opinion?

I can remove the file, but than I need to put an #ifdef construct in
start.S to only exclude it in the lpc2468 case. The file is used by the
other ARM ports. I can also simply empty it, but in this way it is more
similar to the other ports. What would you like?

No, none at all. There is only a single linear memory region for the
processor and a write to a location has immediate effect, whether it be
a register or just RAM.
I suppose leaving parts of the 2468 and 2292 code separated is OK for
the time being (considering offset lists and data structures), in the
hope someone will upgrade the 2292 code?
I'm willing to look into the PUT32() vs. writel() problem in about half
a year or so. That will at least cleanup part of the code.
Kind regards,
Remco Poelstra

I'm preparing a patch series to clean the arm720t to seprate it as arch
and avoid this borring #ifdef

immap.h is like hardware.h for the LPC2292, but it contains C structures
to define the registers instead of #defines. I based it on the ppc code.
See the patch for an explanation.

I do not understand what you mean with the last part of your comment.

IAP entries need thumb code. This is not a problem, they are only used
for programming the internal flash of the processor, so there is no
performance penalty for normal operation.

Thanks for the pointer, I'll look into those.

Can you explain what you mean here?

Hi,
This patch is outdated. After the part 1 patch is OK, I'll work on this
part. I'll include your comments then.

I can't find these functions/macros, but I think you mean the
write{b,s,l} macros. As I already indicated in a previous e-mail, they
do not work in my code. If I replace, e.g. the PUT32 with writel than
the code doesn't run. I will look into that problem after I've finished
another project at work.
Kind regards,

This patch includes support for the LPC2468 processor from NXP.
Signed-off-by: Remco Poelstra <remco.poelstra+u-boot@duran-audio.com>
---
A working board example will be submitted when this patch is found to be OK.
This patch is against latest git.
The previous problem with PUTx vs. writex is solved.

Would it be possible to keep a generic ``#include <asm/hardware.h>''
here and add the processor specific stuff there?

Can we please move this out of a common source file?

Indentation not by TAB (whole file!).
How about adding some comments to explain what all these fields mean?
(whole file!)

No, not really. Stefan cares only about the CFI driver, and this is
clearly not a CFI conformant flash type.

I took a quick look at the flash "driver". The main functions
lpc24xx_flash_erase() and lpc24xx_write_buff() are not even referenced
somewhere in this patch. They seem to be used in the 2nd patch (2/2) though.
It's hard to really understand what's going on here. So this flash driver
part really needs some sort of documentation how it's supposed to work.
And I also think this driver (as all FLASH related drivers) should be moved
into drivers/mtd instead.
Best regards,
Stefan

Into drivers/mtd? Even if it's not a MTD driver? This doesn't make
mnuch sense to me.

In the end this driver will be used by the common FLASH user interface
(cmd_flash.c, cmd_mem.c). So I prefer to have the "driver" for this interface
in a common place for a better overview. And the only common place I can
think of is drivers/mtd right now. We should probably add a subdirectory for
NOR flash drivers: drivers/mtd/nor (or drivers/mtd/maps as done in Linux).
BTW: This common place will prevent those multiple platform/board specific
flash drivers we have right now as well.
Best regards,
Stefan

Yes. But MTD is a description of a specific interface. Even now we
have two versions of the CFI driver: drivers/mtd/cfi_flash.c and
drivers/mtd/cfi_mtd.c, and if we look closer at it only cfi_mtd.c
makes sense in this directory. cfi_flash.c is *not* MTD conformant
and should be somewhere else.

Maybe we should create drivers/flash for those non-MTD flash drivers?
Then we should also move cfi_flash.c there.
> NOR flash drivers: drivers/mtd/nor (or drivers/mtd/maps as done in Linux).
Um... this is something different - in Linux all flash drivers (at
least all in mainline) are handled through the MTD layer.

We agree on that.

No, we don't have "two versions of the CFI driver". cfi_mtd.c is not really a
driver but "only" a wrapper implementing the MTD infrastructure on top of the
U-Boot NOR driver (cfi_flash or others).

Yes, this could be done.

This patch includes support for the LPC2468 processor from NXP.
Signed-off-by: Remco Poelstra <remco.poelstra+u-boot@duran-audio.com>
---
It now also includes support for the ethernet interface.
It does not include any changes to flash related code, until it's known
where to put it. Stefan was right that the unreferenced function are needed
by the board code.
Neither does it contain any significant changes to the interrupt code,
waiting for the patch to clean it up.
I would be gratefull if the patch can be applied before then, I can then help
clean up the code, instead of staying behind.
Concerning thumb code: As explained earlier, it is needed to call the internal
IAP functions. These are seldom used, so there is no performance penalty.

I don't know if 'writel' and 'readl' are the correct accessors for ARM.
Hopefully somebody'll chime in on that.

This looks to me like board code. If it is, it doesn't belong in this

Please don't use this old API. Instead, use the CONFIG_NET_MULTI API
where a 'struct eth_device' is allocated, initialized and filled. This
struct contains a 'priv' field that you can use to store the static
variables that were defined at the top of the driver. The API you've
used is on its way out. You'll find plenty of examples in drivers/net.
