efi_loader: Fix typo in distro script

2016-06-24T21:24:41+00:00

The distro script is supposed to use the internal fdt as fallback if we
find no viable other option. However, we're missing a space key to actually
make that work.

Add the space, so we can successfully load an EFI blob even when there is
no device tree provided on the target device.

distro: Add efi pxe boot code

2016-05-27T19:39:45+00:00

Now that we can expose network functionality to EFI applications,
the logical next step is to load them via pxe to execute them as
well.

This patch adds the necessary bits to the distro script to automatically
load and execute EFI payloads. It identifies the dhcp client as a uEFI
capable PXE client, hoping the server returns a tftp path to a workable
EFI binary that we can then execute.

To enable boards that don't come with a working device tree preloaded,
this patch also adds support to load a device tree from the /dtb directory
on the remote tftp server.

dm: scsi: Rename CONFIG_CMD_SCSI to CONFIG_SCSI

2016-05-17T15:54:43+00:00

This option currently enables both the command and the SCSI functionality.
Rename the existing option to CONFIG_SCSI since most of the code relates
to the feature.

efi_loader: Fall back to fdtfile naming convention

2016-04-18T21:11:50+00:00

When there is no $fdtfile variable set, we still have a good chance
that on 32bit arm the fdtfile really is just called $soc-$board.dtb.

Enable the exports for $soc and $board in our distr defaults and make
use of them in the efi boot script.

efi_loader: Pass fdt address directly to bootefi cmd

2016-04-18T21:11:49+00:00

The bootefi cmd today fetches its device tree pointer from either the
location appointed by "fdt addr" with a fallback to the U-Boot control
fdt.

This integration is unusual for U-Boot and diverges from the way we
usually handle parameters to boot commands. So let's pass the fdt
directly into the bootefi command instead and move the control fdt
logic into the distro boot script.

arm64: Replace fdt_name env variables with fdtfile

2016-03-16T01:30:13+00:00

The commonly defined environment variable to determine the device tree
file name is called fdtfile rather than fdt_name. Replace all occurences
of fdt_name with fdtfile.

efi_loader: Add distro boot script for removable media

2016-03-16T01:30:11+00:00

UEFI defines a simple boot protocol for removable media. There we should look
at the EFI (first GPT FAT) partition and search for /efi/boot/bootXXX.efi with
XXX being different between different platforms (x86, x64, arm, aa64, ...).

This patch implements a simple version of that protocol for the default distro
boot script. With this we can automatically boot from valid UEFI enabled
removable media.

Because from all I could see U-Boot by default doesn't deliver device tree
blobs with its firmware, we also need to load the dtb from somewhere. Traverse
the same EFI partition for an fdt file that fits our current board so that
an OS receives a valid device tree when booted automatically.

distro bootcmd: enumerate PCI before network operations

2016-01-29T04:01:23+00:00

The PCI bus must be enumerated before PCI devices, such as Ethernet
devices, are known to U-Boot. Enhance the distro boot commands to perform
PCI enumeration when needed.

distro bootcmd: make net boot only optionally start USB

2016-01-29T04:01:23+00:00

Currently, the distro boot commands always enumerate USB devices before
performing network operations. However, depending on the board and end-
user configuration, network devices may not be attached to USB, and so
enumerating USB may not be necessary. Enhance the scripts to make this
step optional, so that the user can decrease boot time if they don't
need USB.

This change is performed by moving the "usb start" invocation into a
standalone variable. If the user desires, they can replace that
variable's value with some no-op command such as "true" instead.

Booting from a USB storage device always needs to enumerate USB devices,
so this action is still hard-coded.
