[U-Boot] [PATCH 1/8] omap: overo: allow the use of a plain text env file instead boot scripts

[Ash Charles]

Adapted from d70f5480 described below.

    commit d70f54808dfa83b574e1239c3eccbcf3317343e1
    Author: Javier Martinez Canillas <javier@dowhile0.org>
    Date:   Mon Jan 7 03:51:20 2013 +0000

    omap4: allow the use of a plain text env file instead boot scripts

    For production systems it is better to use script images since
    they are protected by checksums and carry valuable information like
    name and timestamp. Also, you can't validate the content passed to
    env import.

    But for development, it is easier to use the env import command and
    plain text files instead of script-images.

    Since both OMAP4 supported boards (Panda and TI SDP4430) are used
    primarily for development, this patch allows U-Boot to load env var
    from a text file in case that an boot.scr script-image is not present.

    The variable uenvcmd (if existent) will be executed (using run) after
    uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
    will be started.

[U-Boot] [PATCH 2/8] OMAP3: overo: add command support for mtd and ubi

[Ash Charles]

The NAND linux partition format default was changed from jffs2 to ubi in
254973e6df0e48f1a72b67905185c774dcd9f394 but the corresponding commands were
not enabled.

[U-Boot] [PATCH 3/8] OMAP3: overo: increase linux partition to 8 MiB

[Ash Charles]

From: "Peter A. Bigot" <pab@pabigot.com>

Linux kernel at version 3.5 is about 3.5 MiB; test kernels for 3.10 exceed 4
MiB.  Prepare for future upgrades by increasing the NAND partition now.

[U-Boot] [PATCH 4/8] OMAP3: overo: eliminate hard-coded partition offsets

[Ash Charles]

The linux kernel is at nand0,3 using the current layout, but is best
accessed through the partition label "linux".  Since CONFIG_CMD_MTDPARTS is
defined the CONFIG_JFFS2 settings are unreferenced; use "setenv partition
rootfs" to set the default mtd partition for jffs2.

[U-Boot] [PATCH 5/8] arm: omap3: Fix omap3_overo SPL boot hangup

[Ash Charles]

Patch f33b9bd3
[arm: omap3: Enable clocks for peripherals only if they are used]
breaks SPL booting on Overo. Since some gpio inputs are
read to detect the board revision. But with this patch above, the
clocks to the GPIO subsystems are not enabled per default any more.
The GPIO banks need to be configured specifically now.

Bluetooth module: Wi2Wi's W2CBW0015.  No other code changes are required
in u-boot---just handling of this particular board revision.

Please see DEFAULT_LINUX_BOOT_ENV and the related discussions.  If you
have less than 128MB DDR we can sort something out, but if you have
256MB it's really advised to use 0x88000000 for the DT (see
Documentation/arm/Booting in the kernel).

Overo doesn't pull in the configuration from
include/configs/ti_armv7_common.h where DEFAULT_LINUX_BOOT_ENV is
defined.  Might a v2 using the settings defined by
DEFAULT_LINUX_BOOT_ENV in the overo config be acceptable?

I'd like to start by seeing if we can adopt the files (ti_omap3_common.h
which grabs ti_armv7_common.h).  The intention is to have the
really common parts there and the board specific elsewhere.  It's indeed
not quite perfect and we probably need to push a few things back up to
the board, even if they're repeated frequently.

Thanks Tom.
As this is a rather distinct change, I'm sending an additional patch
that switches Overo to ti_omap3_common and DEFAULT_LINUX_BOOT_ENV
rather than amending the previous patch series.  I hope this is
appropriate and acceptable as I wasn't sure the policy on such patches
after the close date for the merge window.

Another newbie question: should I be basing submitted patches off
u-boot-ti/master (as I'm using TI chips) or u-boot/master?

[U-Boot] [PATCH] omap3: overo: Use common configurations for Overo

[Ash Charles]

Clean-up the board configuration file for the Gumstix Overo board by
including common omap3 definitions from ti_omap3_common.h as suggested
here [1].

Totally correct---good catch.
I'll send a v2 for this series rebased on u-boot-ti/master and also
include this [1] patch.  Hopefully this is correct.

    omap4: allow the use of a plain text env file instead boot scripts

    For production systems it is better to use script images since
    they are protected by checksums and carry valuable information like
    name and timestamp. Also, you can't validate the content passed to
    env import.

    But for development, it is easier to use the env import command and
    plain text files instead of script-images.

    Since both OMAP4 supported boards (Panda and TI SDP4430) are used
    primarily for development, this patch allows U-Boot to load env var
    from a text file in case that an boot.scr script-image is not present.

    The variable uenvcmd (if existent) will be executed (using run) after
    uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
    will be started.

[U-Boot] [Patch v2 2/9] OMAP3: overo: add command support for mtd and ubi

[Ash Charles]

The NAND linux partition format default was changed from jffs2 to ubi in
254973e6df0e48f1a72b67905185c774dcd9f394 but the corresponding commands were
not enabled.

[U-Boot] [Patch v2 3/9] OMAP3: overo: increase linux partition to 8 MiB

[Ash Charles]

From: "Peter A. Bigot" <pab@pabigot.com>

Linux kernel at version 3.5 is about 3.5 MiB; test kernels for 3.10 exceed 4
MiB.  Prepare for future upgrades by increasing the NAND partition now.

[U-Boot] [Patch v2 4/9] OMAP3: overo: eliminate hard-coded partition offsets

[Ash Charles]

The linux kernel is at nand0,3 using the current layout, but is best
accessed through the partition label "linux".  Since CONFIG_CMD_MTDPARTS is
defined the CONFIG_JFFS2 settings are unreferenced; use "setenv partition
rootfs" to set the default mtd partition for jffs2.

[U-Boot] [Patch v2 5/9] arm: omap3: Fix omap3_overo SPL boot hangup

[Ash Charles]

Patch f33b9bd3
[arm: omap3: Enable clocks for peripherals only if they are used]
breaks SPL booting on Overo. Since some gpio inputs are
read to detect the board revision. But with this patch above, the
clocks to the GPIO subsystems are not enabled per default any more.
The GPIO banks need to be configured specifically now.
