[U-Boot] [PATCH 0/7] PXE parsing fixes and local file support

[Rob Herring]

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

The first 6 patches are menu file parsing fixes found in testing ubuntu/
debian generated menu files. The menu display is cleaned up to display
the friendly menu label string and boot the default image on timeout as
is typical for a PC bootloader.

The last patch adds support for parsing local disk files on ext2 or fat
filesystems. This is essentially syslinux/extlinux emulation and simply
reuses the existing pxe support.

Rob

Rob Herring (7):
  menu: only timeout when menu is displayed
  pxe: support include files at top-level
  pxe: add support for label menu text
  pxe: support linux entries for labels
  pxe: support absolute paths
  pxe: parse initrd file from append string
  pxe: add support for parsing local syslinux files

[U-Boot] [PATCH 1/7] menu: only timeout when menu is displayed

[Rob Herring]

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

Make the menu timeout apply only when prompt flag is set and after the
menu is displayed. This allows auto boot to work no matter whether prompt
is set or cleared. Use the default selection if the menu times out.

This also fixes the timeout value given to readline_into_buffer to be
seconds instead of 10th of seconds.

Old behavior:

if prompt
  display menu and wait for choice
else
  wait for timeout
  if key pressed
    display menu and wait for choice
  else
    exit command

New behavior:

if prompt
  display menu
  if key pressed
    wait for choice
  else
    boot default entry on timeout
else
  boot default entry

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

Kernels can be specified using "linux" or "kernel" entry. The difference
is kernel is supposed to detect the type of file, but for u-boot both are

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

Add a new command "sysboot" which parses syslinux menu files and boots
using kernel and initrd specified by menu files. The operation is similar
to "pxe boot" except local files on ext2 or fat filesystem are parsed.

I attempted to apply this patch but it failed.

Applying: pxe: add support for parsing local syslinux files
error: patch failed: common/cmd_pxe.c:322
error: common/cmd_pxe.c: patch does not apply
fatal: sha1 information is lacking or useless (common/cmd_pxe.c).
Repository lacks necessary blobs to fall back on 3-way merge.
Cannot fall back to three-way merge.

Please rebase the series and resend.

Thanks,

I rebased to Wolfgang's current master without any conflicts, so I'm
puzzled why this failed for you. I was originally based on this commit
plus a few otherwise unrelated highbank fixes:

I just tried again on u-boot.git/master...

Note: moving to "origin/master" which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at b86a475... MAKEALL: Report boards with errors vs warnings

Patch failed@0007.
When you have resolved this problem run "git am --resolved".
If you would prefer to skip this patch, instead run "git am --skip".
To restore the original branch and stop patching run "git am --abort".

I'm attempting to apply these patches in patchwork:

http://patchwork.ozlabs.org/patch/149281/
http://patchwork.ozlabs.org/patch/149280/
http://patchwork.ozlabs.org/patch/149282/

http://patchwork.ozlabs.org/patch/149286/
http://patchwork.ozlabs.org/patch/149285/

in that order... is that incorrect?

Thanks

Any luck figuring out why the patch at
http://patchwork.ozlabs.org/patch/149285/ will not apply?  Perhaps
just rebase (since that works for you) and resend.

[U-Boot] [PATCH v2] pxe: add support for parsing local syslinux files

[Rob Herring]

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

Add a new command "sysboot" which parses syslinux menu files and boots
using kernel and initrd specified by menu files. The operation is similar
to "pxe boot" except local files on ext2 or fat filesystem are parsed.

Signed-off-by: Rob Herring <rob.herring@calxeda.com>
---
v2:
- rebase to current mainline
- fix compile if ext2 or fat is disabled
