Good morning - and happy new year!
Something seems fishy here.
Yesterday when trying to send out this patchset my ISP said
[PATCH 01/25] ... was spam and rejected the mail.
So I used an alternative smtp provider (also my POP3 provider).
And tested this towards my work mail - OK.
And when sent to barebox mailing list I got the cc: mails.
But I can see that no mails have reached the Barebox mailing
list for this or the following patch-set.
(Checked the web version) So something is not OK.
I tried again this morning, and mails sent using git send-email
will reach my work mail.
The mails leave my smtp provider, but are lost somewhere
on the way to the barebox mailing list.
Mail header looks like this (mail copied to myself):

I managed to send most mail out using my normal smtp server.
And then I used Google smtp to send the remaining mails.
So they are out order - sorry.
This was not what I had planned to start the new year with.

I have tracked down the culprint.
If my mails include following address:
<http : // www . calao-systems . com>
then they are marked as spam.
My first mail to ISP helpdesk was answered by a less skilled person.
Hopefully the second mail reaches a person that at least can read
all of my mail.
I have no clue what kind of blacklisting they use.
I checked here:
https://mxtoolbox.com/blacklists.aspx
and all reported OK.
I hope they find a way to fix it.
Until then I may have to revert to the Google smtp solution.

longer used.
Delete the file and the now unused CONFIG symbol and it uses

To prepare moving reset code to board code create at91sam926x_board_init.h.
at91sam926x_board_init.h is a copy of at91sam926x_lowlevel_init.c
with a few changes:
- We no longer call board code from this function
- The struct is renamed to avoid name clashes
- Function renamed to better match the prurpose
This file allows board code to include at91sam926x_board_init.h
and use the init functions in their init code.
Users must select AT91SAM926X_BOARD_INIT

Move reset code to the board specific code.
This drops the dependency where mach-at91/ code
calls into the board code.
Drop the now (for this board) unessesary CONFIG select's

All at91sam9261 based boards uses board specific
reset vectors so the mach-at91 provided version is
no longer in use.
Delete unused CONFIG symbols too.

I suspect this hasn't seen any testing for a long time. The lowlevel
code was converted from Assembler to C by Jean Christophe who probably
doesn't have this hardware. It was built without lowlevel config for
quite some time without anybody noticing. Let's just remove this board
instead of ventilating it any further.

Ack, will do so as the first patch in this series.

These three board share the same at91sam9g45_lowlevel_init.c file.
Introduce lowlevel.c file for the boards that contains the reset vector.
Delete the now unused at91sam9g45_lowlevel_init.c file
Drop unused CONFIG symbols and Makefile references

To: Barebox List; +Cc: Sam Ravnborg
The aim with this conversion is to drop the dependency
where the mach-at91/ code call code in the boards file.
This dependency must be dropepd to enable multi-image builds.
The selection of lowlevel_init functions are pushed to
the individual boards.
Use AT91SAM926X_BOARD_INIT for the boards that share the
at91sam926x_board_init file, and push this to the
individual boards.
bootstrap is likewise pushed out to the individual boards.

I think this just goes down to a missing "select HAVE_AT91_LOWLEVEL_INIT"
Can we add it instead and keep the existing init code with this series?

For all Calao USB boards move reset vector to board code.
Introduce two different lowlevel.c files, one
for each processor.
Include a rename to make filenames similar.
