[U-Boot] [PATCH 01/11] am335x: make get_board_rev() function weak

[Igor Grinberg]

Current get_board_rev() function returns a hard coded value which is
obviously incorrect for the majority of boards.
Allow boards to provide a correct implementation by making this
function weak.

[U-Boot] [PATCH 04/11] omap3: cm-t35: extract the splash code from board

[Igor Grinberg]

The splash screen loading code can be reused by other compulab boards.
For now extract it to a common location for further reuse.

This also switches the splash code dependency from CONFIG_LCD to
CONFIG_SPLASH_SCREEN as it should normally be.

In addition this patch fixes the accidental dependency of the
get_board_mem_timings() function on CONFIG_LCD, by just moving the
splash code and leaving the above function intact.

[U-Boot] [PATCH 06/11] omap3: cm-t35: move get_board_serial() fallback

[Igor Grinberg]

The fallback is used for cases when CONFIG_SERIAL_TAG defined, but the
eeprom is not used.
The fallback is useful for more than one CompuLab board, so move it to a
common location.

[U-Boot] [PATCH 07/11] omap: hsmmc: assume cd gpio is active low

[Igor Grinberg]

Switch the default CD GPIO polarity to active low.

The current hsmmc driver assumption that the CD GPIO is active high, but
in the real hardware, usually the opposite holds.
The usual SD card socket has a mechanical switch which is grounded as
soon as a card is inserted.
Of course there might be some board logic which inverts the signal, but
as far as current users are concerned, there is no such logic.

Current U-Boot users either not using the CD functionality, or have a
different way (e.g. external to SoC GPIO controller) for checking the
card presence.

This patch also brings the polarity assumption in line with the Linux
kernel and adds appropriate comments.

This patch also might spare issues once the TWL GPIO driver will be
converted to the DM.

[U-Boot] [PATCH 09/11] omap3: cm-t3517: add USB support

[Igor Grinberg]

Add both host and mUSB support.
Currently, the selection between host USB and mUSB is done through the
config file.

Which is a hard-coded 0 anyhow.  Can you please update the comment to
say something along the lines of "Return 0 for the ATAG REVISION tag
value" along with making it weak and nuke BOARD_REV_ID from the header
as well?  Thanks!

The big comment about layout at the top of
include/configs/ti_armv7_common.h applies to omap3 too, are you sure you
want to go in the direction instead?  In fact, are you sure you can't /
don't want to leverage that file?

[U-Boot] [PATCH v2] am335x: make get_board_rev() function weak

[Igor Grinberg]

Current get_board_rev() function returns a hard coded value which is
obviously incorrect for the majority of boards.
Allow boards to provide a correct implementation by making this
function weak.
In addition open code the trivial and useless BOARD_REV_ID define and
adjust the comment.

Well, the only concern about the using common configurations in general
is the breakage it can introduce as changes to those files are never tested
on all the boards that include them. Hopefully, this will be (at least
partially) solved by defconfigs.
As same stands also for fixes, I think we can take the chances.
Switching to use the common config file will require some additional checks
like undef unneeded stuff and also check the binary size impact.
I might be unable to do those soon enough for this patchset to be included
in the release.

Do you mean the one in ti_omap3_common.h?
Well, that is the same question as above (and also the same answer).

The question is can we proceed with only the below fixed and I will update
the above and common config file inclusion later (also for cm-t35)?

No, not really... Thanks for pointing to this.
I usually try to keep myself up to date, but recently, I have
way to much stuff going on, so those small things are slipping through.

Aaand now I have egg on my face, I was referring to

... maybe.  I need to think about it I suppose.

[U-Boot] [PATCH v2 8/11] omap3: cm-t3517: add basic board support

[Igor Grinberg]

CompuLab cm-t3517 is Computer on Module (CoM) based on AM3517 SoC.
Features: up to 256MB DDR2, up to 512MB NAND, USB hub, mUSB, WiFi, BT,
Analog audio codec, touch screen controller, LED.

Add basic support including:
LED, Serial console, NAND, MMC, GPIO, I2C, 256MB DRAM.

Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>
