[JFFS2] Remove support for virtual blocks
Remove support for virtual blocks, which are build by concatenation of multiple physical erase blocks. For more information please read the MTD mailing list thread "[PATCH] remove support for virtual blocks" Signed-off-by: Ferenc Havasi <havasi@inf.u-szeged.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
