[U-Boot] [PATCH 01/10] pxe: Use ethact setting for pxe

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Get the MAC address using eth_getenv_enetaddr_by_index so that the MAC
address of ethact is used. This enables using the a NIC other than the
first one for PXE boot.

[U-Boot] [PATCH 03/10] pxe: fix handling of different localboot values

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Add support for value of -1 For localboot. A value of -1 means return to
u-boot prompt.

The localboot value is often 0, so we need to distinguish the value from
localboot being selected. A value of greater than or equal to 0 means
attempt local boot command.

If localboot is selected, we don't want to try other entries.

[U-Boot] [PATCH 06/10] pxe: always display a menu when present

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

The prompt flag is for displaying a "boot:" prompt in pxelinux. This
doesn't make sense for u-boot as we don't support the pxelinux command
interface. So we should just ignore prompt statements and always show the
menu if a menu is present.

[U-Boot] [PATCH 08/10] pxe: add support for ontimeout token

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

ontimeout is similar to default, but is the selection on menu timeout.
This is how cobbler sets a default. The label default is supposed to be
the default selection when <enter> is pressed. If both default and
ontimeout are set, last one parsed wins.

[U-Boot] [PATCH 09/10] pxe: add support for per arch and SoC default paths

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

A pxelinux server setup for "default" menu is typically an x86 binary.
This does not work well with a mixed architecture setup. Extend the default
search to look for default-<arch>-<soc> and then default-<arch> before
falling back to just "default".

[U-Boot] [PATCH 05/10] pxe: use bootz instead of bootm when enabled

Why would this be the case?  We should encourage the use of a
checksum-protected image format, i. e. the default setting should be
for FIT images, followed by legacy U-Boot images, and fall back on
archaic formats like zImage only when there is really no other way.


Best regards,

Wolfgang Denk

There is no way for the client to tell the server what kind of client it
is and therefore what kind of image to serve. There is the dhcp client
id string, but that can't be used in situations were you don't control
the dhcp server setup. That problem is also the reason for patch 9 where
you can't distinguish between x86 and ARM for "default".

When we have systems that boot from UEFI, they will certainly not use
u-boot image formats and we don't want to have different setup based on
the client/bootloader type.

I can actually just make this run-time rather than compile time. When
do_bootm returns when it fails to find a valid u-boot image, I can just
call do_bootz.

[U-Boot] [PATCH v2] pxe: try bootz if bootm fails to find a valid image

[Rob Herring]

From: Rob Herring <rob.herring@calxeda.com>

Standard pxelinux servers will typically use a zImage rather than u-boot
image format, so fallback to bootz if bootm fails.

v2:
- Only fall back to bootz when bootm fails instead of being either or
  option.
