PATCH 1/8 omap: overo: allow the use of a plain text env file instead boot scripts

Adapted from d70f5480 described below.

commit d70f54808dfa83b574e1239c3eccbcf3317343e1
Author: Javier Martinez Canillas <[email protected]>
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.

PATCH 2/8 OMAP3: overo: add command support for mtd and ubi

In reply to Ash Charles

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

PATCH 3/8 OMAP3: overo: increase linux partition to 8 MiB

In reply to Ash Charles

From: "Peter A. Bigot" <[email protected]>

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.

PATCH 4/8 OMAP3: overo: eliminate hard-coded partition offsets

In reply to 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.

PATCH 5/8 arm: omap3: Fix omap3_overo SPL boot hangup

In reply to 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.

Gumstix Overo COMs with board revision 0x4 use a different Wifi and 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).

PATCH 8/8 Allow overo to boot with device tree

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.

PATCH 8/8 Allow overo to boot with device tree

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?

PATCH v2 1/9 omap: overo: allow the use of a plain text env file instead boot scripts

Adapted from d70f5480 described below.

commit d70f54808dfa83b574e1239c3eccbcf3317343e1
Author: Javier Martinez Canillas <[email protected]>
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.

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.

PATCH v2 2/9 OMAP3: overo: add command support for mtd and ubi

In reply to Ash Charles

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

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.
