[PATCH 1/1] riscv: select CONFIG_ARCH_KEEP_MEMBLOCK

[Heinrich Schuchardt]

For analyzing memory blocks we can either use the memblock=debug command
line argument which creates massive output or a debug file system.

Select CONFIG_ARCH_KEEP_MEMBLOCK to provide a debugfs at
/sys/kernel/debug/memblock to analyze memory blocks. The
same is already done for arm, arm64, mips, powerpc.

The actual provisioning of the file system depends on CONFIG_DEBUG_FS.
