[PATCH 0/9] RAMOOPS read support for Barebox

[Markus Pargmann]

Hi,

These patches add support to read RAMOOPS files that were written by the last
booted kernel.

The first patches 1-4 add minor functions to barebox from the linux kernel.

Patch 5 adds reed solomon codes as library routines.

Patch 6-7 cleanup the current memory offset calculations for arm. There are a
lot of hardcoded sizes in the current code. I tried to centralize these sizes.

Patch 8 adds a memory region right after the barebox image before the stack for
RAMOOPS. This avoids any ramoops dependencies between different barebox
versions (unless the stack size is changed).

Patch 9 adds the actual implementation of pstore and RAMOOPS as filesystem. It
is based on the kernel implementation but lots of code was removed and the
filesystem layer rewritten for barebox. The files are available in the
automounted filesystem /pstore.

Best Regards,

Markus
