This driver seems to be obsolete and broken for a long time. It depends on CONFIG_IPAQ_HANDHELD that simply doesn't exists anywhere in kernel. Also, it seems that none of machines it claims to support have any need in it: SA11xx-based iPAQs (h3100/h3600) use sa1100-flash iPAQ h5000 uses physmap-flash Jornada 720 uses sa1100-flash Jornada 560 and iPAQ h1910 are not in mainline Signed-off-by: Dmitry Artamonow <mad_soft@inbox.ru> Cc: Russell King <linux@arm.linux.org.uk> --- drivers/mtd/maps/Kconfig | 6 - drivers/mtd/maps/Makefile | 1 - drivers/mtd/maps/ipaq-flash.c | 460 ----------------------------------------- 3 files changed, 0 insertions(+), 467 deletions(-) delete mode 100644 drivers/mtd/maps/ipaq-flash.c
