boot: extlinux: Fix unaligned buffer for reading data from file system

2024-11-18T14:23:56+00:00

extlinux_read_bootflow() allocates a buffer to read from file system
without any alignment.

But for some block devices which transfer data via DMA, ARCH_DMA_MINALIGN
alignment is required. For example, due to misaligned buffer, the below
boot failure is observed.

=> boot
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
** Booting bootflow 'mmc@2194000.bootdev.part_1' with extlinux
Ignoring unknown command: �D���D��
Boot failed (err=-14)

Change the buffer alignment to ARCH_DMA_MINALIGN.

bootstd: Add command to enable setting of bootmeth specific properties

2024-10-15T16:24:27+00:00

We have previously added logic to allow a "fallback" option to be
specified in the extlinux configuration. Provide a command that allows
us to set this as the preferred default option when booting.

Combined with the bootcount functionality, this allows the "altbootcmd"
to provide a means of falling back to a previously known good state
after a failed update. For example, if "bootcmd" is set to:

    bootflow scan -lb

We would set "altbootcmd" to:

    bootmeth set extlinux fallback 1; bootflow scan -lb

Causing the boot process to boot from the fallback option.

boot: Add logic to enable booting from fallback option

2024-10-15T16:24:27+00:00

The "fallback" extlinux config option allows us to set an alternative
default boot option for when it has been detected that the default is
failing. Implement the logic required to boot from this option when
desired.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay

so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing

bootstd: Adjust the default bootmeth order

2023-08-28T19:59:22+00:00

The existing distro scripts check extlinux and scripts before EFI. Adjust
the default ordering to do the same, to avoid breaking existing flows.

Add some documentation, mentioning that this order will likely change in
future.

bootstd: Fix relative path use in extlinux bootmeth

2023-06-14T16:56:10+00:00

Using relative path in a /boot/extlinux/extlinux.conf file fails to load
linux kernel.

Using a /boot/extlinux/extlinux.conf file:

  LABEL test
    LINUX ../linux/Image

Result in following error:

  Retrieving file: ../linux/Image
  Skipping test for failure retrieving kernel
  Boot failed (err=-14)

However, using sysboot cmd successfully load kernel using same file:

  sysboot mmc 1:1 any ${scriptaddr} /boot/extlinux/extlinux.conf

  Retrieving file: /boot/extlinux/../linux/Image

Fix relative path using bootmeth extlinux by supplying bootfile path
instead of subdir path in the call to pxe_setup_ctx, same as done in the
sysboot command.
