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.

config_distro_bootcmd.h: Use a private variable for bootpart

2015-10-22T18:18:31+00:00

Hush has an oddity where using ${var} causes var to resolved in the the global
address space (iotw the environment) first and only afterwards will the local
variable space be searched.

This causes odd side-effects when iterating over the boot partitions
using ${bootpart} if the environment also has a bootpart variable (e.g. for
the various TI boards). Fix this by using the hopefully more unique
${distro_bootpart} instead of ${bootpart}.
