The enbw_cmc board boots from NOR flash with the NOR
direct boot method.

Heiko Schocher (8):
  arm, davinci: add SYSCFG1 base and register struct
  arm, davinci: add some missing defines in hardware.h
  arm, davinci, am1808, gpio: add missing defines for bank 8
  arm, davinci: add ddr2 definition
  arm, davinci: add NOR Boot Configuration Word
  arm, davinci, am1808: add lowlevel functions for booting from NOR
  arm, davinci, da8xx: add cpuinfo
  arm, davinci: add support for am1808 based enbw_cmc board

There is a new standard option for assigning the machid.
Now, this should be done in the board config file and the above two lines removed.
Please, see the CONFIG_MACH_TYPE in the U-Boot documentation (README file).

Consider adding here:
#define MACH_TYPE_ENBW_CMC	3585
#define CONFIG_MACH_TYPE	MACH_TYPE_ENBW_CMC

- changes for v2
  - use CONFIG_MACH_TYPE instead setting the MACH_TYPE in
    board specific code, as Igor Grinberg suggested.
  - add logversion=2 to default Environment

Heiko,

I applied all your patches and MAKEALL returned a failure for only the enbw_cmc board.

Can you please take a look?

Because of this I have not applied this to u-boot-ti.

Regards,
Sandeep

Hmm.. just did a rebase to TOT and I see with all my patches:

Did you apllied all patches, as stated here?:

ah, i did not see the entire list of dependencies.
I did not apply all the patches as some of them should not be applied by me.

i have sent Albert a pull request without this patch for the time being.

Hope by the next pull request, all the dependencies would have made it to mainline.

Regards,
Sandeep

Hmm.. maybe you can post your compileerror, so I can see which patch
is missing?

Heiko,
I am looking forward to see these patches in mainline u-boot. My
custom board also directly boots from NOR, so I think there is a lot I
can re-use for my board.
I have one question, please see below:

There is some similar code in arch/arm/cpu/arm926ejs/davinci/psc.c. Is
there any reason why you don't use this code or adapt it for your
needs?

No, there is no reason, just missed it! I try the functions in
arch/arm/cpu/arm926ejs/davinci/psc.c and if they work, I remove the
am1808_lpc_transition function.

Thanks!

Heiko

Hello Heiko,
Thank you for your reply. I have just noticed that the patches have
already been pulled into arm/next so I guess I am quite late with my
comments. I'd like to apologize for this; apparently I need another
email filter that also filters for messages containing "am1808" and
not only "da850" ;-)

Which brings me to my next point: AFAIK Texas Instruments's AM18xx
SoCs, their OMAP-L138, and their DA850 based devices basically differ
only in the DSP/PRU part of the device. If you are (like in u-boot)
only interested in the ARM part of chip, they are basically the same
device. For some reason the Linux kernel and u-boot support for all
these devices is labelled da850... Although I have no hardware to test
it, I guess that your DDR memory controller initialization code could
be used for the OMAP-L138 and the corresponding Davinci device as
well. So since all code in u-boot for the entire device family is
labelled da850... I guess your DDR initialization functions should get
this prefix as well for consistency. Any comments from the
maintainers/TI employees who know these devices better than I do?

Ok. Actually you do LPSC transitions twice in your board
configuration, first in the low level initialization in
arch/arm/cpu/arm926ejs/davinci/am1808_lowlevel.c (using your own
function) and then again in your board initialization in
board/enbw/enbw_cmc/enbw_cmc.c (using the code in
arch/arm/cpu/arm926ejs/davinci/psc.c). I assume you ran into the same
problem as I did with the da850evm board. The UART is used before it
is turned on in the board_init() function. A few weeks ago I submitted
a patch [1][2] for this issue but did not get any comments on it.
Would you mind having a look at it so we could find a common solution
for both your configuration and the da850evm?

Note that at least some of the dependencies are in /next branches, so 
they won't appear in u-boot[-arm]/master until the upcoming merge window

Yes of course, such a rename should be done, if somebody has tested it!

I just wonder what is worse, having code in there that is labelled
da850 but not tested on all devices of the family, or having it
renamed every time someone finds out that it also runs on other
devices. TI uses a common PLL initialization code in its User Boot
Loader (UBL) for OMAP-L138, DA850, AM180x, so it should be pretty save
to rename it right now.

Did you also read the rest of my last email, the PSC part?

a) you are right, I enable the PSC for the UART twice, what is not
   optimal! I remove this in my board code. Thanks for detecting
   this!

b) I enable the PSC for the UART in
   arch/arm/cpu/arm926ejs/davinci/am1808_lowlevel.c arch_cpu_init(),
   so the UART is enabled on my board before calling board_early_init_f()
   as in your patch [1]. So I am save on this site.

c) If using the "Legacy NOR Boot" Method with u-boot spl Framework,
   (not tested this with the new Framework, only with the old),
   we are also on the save side here, as the SPL code enables the
   PSC for the UART in arch/arm/cpu/arm926ejs/davinci/am1808_lowlevel.c
   board_init_f(), same as for the "direct NOR boot" method I used
   on the enbw_cmc board.

I think there are two points:

a) move this init to board_early_init_f() as you did it
b) remove the UART enable, as it is done in UBL or U-Boot code (SPL
   or in arch_cpu_init())

But this should be decided from the board maintainer added
Sudhakar Rajashekhara to CC, as it affects the da850 board ...

Heiko

With a 24 MHz input frequency this would result in a PLL0 frequency of
24MHz / PREDIV * (CONFIG_SYS_AM1808_PLL0_PLLM + 1), so I guess you
assume a PREDIV of 2 here (PREDIV register value 0x00008001). However,
the AM1808 datasheet and the reference guide (section 7.3.10) state
that the default PREDIV is 1 (register value 0x00008000) and I don't
see how you set the PREDIV to 2. Am I missing something here?

No. The comment is wrong! I fix the comment from PLL0 to PLLC0
in the next patch version, thanks!

For calculating the resulting frequencies for the used Sysclocks
don;t forget the POSTDIV value

#define CONFIG_SYS_AM1808_PLL0_POSTDIV  1

So the correct calculation is:

(24MHz / PREDIV * (CONFIG_SYS_AM1808_PLL0_PLLM + 1)) / POSTDIV

(And with that, I get 456 MHz ;-)

Ok.

But then you would be running PLL0 with 24MHz *
(CONFIG_SYS_AM1808_PLL0_PLLM + 1) = 912 MHz !? That would be out of
specs since the PLL output frequency must be between 300 and 600 MHz
according to the datasheet.

However, you can't set the PLLM to 37 anyway, since it's only a 5 bit
field, (37 & 0x1f) results in 5, so you only multiply the frequency by
6 in the PLL, resulting in 144MHz PLL frequency.

Regards, Christian

Yep, you are right! Fixed

CONFIG_SYS_AM1808_PLL0_PLLM to 18
CONFIG_SYS_AM1808_PLL0_POSTDIV to 0

Thanks!

Hmm... you are right here also, but I see:

                Pllm

strange ...

Thanks for this review!
