net: Fix incorrect RPC packets on 64-bit systems

2016-07-06T15:45:07+00:00

This patch fixes incorrect RPC packet layout caused by
'long' type size difference on 64 and 32-bit architectures.

net: Optionally use pxe client arch from variable

2016-05-27T19:39:49+00:00

The client architecture that we pass to a dhcp server depends on the target
payload that we want to execute. An EFI binary has a different client arch
than a legacy binary or a u-boot binary.

So let's parameterize the pxe client arch field to allow an override via
the distro script, so that our efi boot path can tell the dhcp server that
it's actually an efi firmware.

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.

net: Fix client identifiers for ARM

2016-05-27T19:37:16+00:00

There are client identifiers specifically reserved for ARM U-Boot
according to http://www.ietf.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xml#processor-architecture.

So let's actually make use of them rather than the bogus 0x100 that
we emitted so far.

net: Move the VCI and client arch values to Kconfig

2016-05-27T14:01:12+00:00

We have a bunch of boards that define their vendor class identifier and
client archs in the board files or in the distro config. Move everything
to the generic Kconfig options.

We're missing the distinction between i386 and x86_64, as I couldn't find
any config variable that would tell us the difference. Is that really important
to people? I guess not, so I left it out.

bootp: Move vendor class identifier set to function

2016-05-27T14:01:11+00:00

Both the dhcp as well as the bootp case add vendor class identifier
parameters into their packets. Let's move that into a separate function
to make overlaying easier.

efi_loader: Add network access support

2016-05-27T14:01:10+00:00

We can now successfully boot EFI applications from disk, but users
may want to also run them from a PXE setup.

This patch implements rudimentary network support, allowing a payload
to send and receive network packets.

With this patch, I was able to successfully run grub2 with network
access inside of QEMU's -M xlnx-ep108.
