This patch should fix the following problem: 1. the jffs2-image update in the u-boot was ok 2. first restart and first mount of the NAND-flash-partition was also ok 3. before the restart of controller there are no any activity on NAND-flash except of the jffs2_gcd_mtdX-process ... 4. BUT after the second restart the NAND-flash-partition could not be really used after the second mount, dmesg filled with messages: ... jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03ce0000: 0xc0ff instead jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x03d00000: 0xc0ff instead .... Just for for info: the behaviour observed on mpc8313-based board with the large-page NAND. The only activity on NAND-flash was the garbage collector process, that looks for CLEANMARKER-nodes As Scott said it was broken by commit 3ab8f2a2e7011c5e83363b42950757e46ef06824 Signed-off-by: Sergej Stepanov <Sergej.Stepanov@ids.de> Cc: Rolf Riehle <Rolf.Riehle@ids.de> Cc: Scott Wood <scottwood@freescale.com> Cc: David Woodhouse <dwmw2@infradead.org> --
