[U-Boot] [PATCH 0/4] Add support for BeagleBoard.org PocketBeagle

[Jason Kridner]

This series sets up the am335x_evm_usbspl_defconfig to boot the TI
AM335x based BeagleBoard.org PocketBeagle using the BeagleBoard.org
provided Debian images and enables NETCONSOLE over USB when the
environment is updated as needed.

[U-Boot] [PATCH 1/4] Add support for BeagleBoard.org PocketBeagle

[Jason Kridner]

Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP
with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x
55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header
pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more.

https://beagleboard.org/pocket

This was tested using the am335x_evm_usbspl_defconfig.

Note that MII pins are enabled despite not having Ethernet on this
board. This avoids an issue where otherwise many timeout errors would be
generated. See https://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976
for some related discussion.

[U-Boot] [PATCH 2/4] am335x_evm: scan more partitions and use uname_r

[Jason Kridner]

This enables mainline u-boot to boot the BeagleBoard.org Debian
distribution builds without extensive environment modifications.

Some boot layouts only have a single partition on the
MMC/eMMC. This will scan those partitions after the second
partition that was already being scanned.

Some layouts use uname_r to define the kernel being used for the boot to
support multiple kernels stored within the boot file system without
using symlinks.

See http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0 for
more details on the BeagleBoard.org Debian image layout.

[U-Boot] [PATCH 3/4] Handle NETCONSOLE and SPL enabled

[Jason Kridner]

From: Jason Kridner <jkridner@beagleboard.org>

NETCONSOLE isn't compiled in with SPL, so the include file needs to recognize that.

Why does this all differ from the usual Debian case?  Thanks!

I believe the distros typically use /boot/extlinux/extlinux.conf. We need
some way to specify a number of other environment variables we use
elsewhere in our u-boot scripts for applying device-tree overlays and such.
This patch doesn't comprehend that. It does at least get our images to boot
without applying any overlays in u-boot.

I believe Robert is preparing a subsequent series to add the application of
overlays.

Do you have something else in mind with regards to envboot's future?

Debian typically uses a boot script, at least when installing from
debian-installer. There's a package called u-boot-menu which generates
the extlinux.conf file. There are some ideas floating around to try to
use u-boot's EFI emulation to boot grub-efi for platforms that don't
support EFI natively, as well.

But the majority of officially supported platforms in Debian still just
use boot scripts, for better or worse.

Could this functionality can't be implemented as a boot script, rather
than hard-coding it into the u-boot binary?

I know the official BeagleBoard.org images have been using a patched
u-boot for quite some time, and so there is something to be said for
pushing that upstream. Though there is a lot of duplication of
functionality supporting distro_bootcmd, legacy boot, and the patchsets
that BeagleBoard.org images use.


live well,
