Ramoops may be useful even without oftree support, as kernels
booted without a DT may have other means to reserve the
ramoops memory.
Fixes:
In function `ramoops_probe':
undefined reference to `of_add_reserve_entry'

pstore is a persistent storage filesystem used for RAMOOPS. It is used
to store console logs, panics, ftrace and other information in case of a
crash/panic/oops/reboot.
pstore is implemented for barebox as a read-only filesystem at the
moment. It may be extended later on. The idea is to provide a way to
extract essential data from the last running kernel.
Most of the code is copied from the kernel. However this is only a
lightweight implementation without real write support yet.
