Subject: [PATCH] ARM: OMAP2+: Fix onenand rate detection to avoid filesystem
corruption
Commit 63aa945b1013 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left
out the option for HWMOD_INIT_NO_RESET as we now require proper timings
for GPMC to be able to remap GPMC devices out of address 0.
Unfortunately on 900, onenand now only partially works with the device
tree provided timings. It works enough to get detected but the clock
rate supported by the onenand chip gets misdetected. This in turn causes
the GPMC timings to be miscalculated and this leads into file system
corruption on n900.
Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.
Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only
need to do this once at the end of omap2_onenand_setup_async().

Bellow is gpmc dmesg output with that fix. I also disabled
CONFIG_OMAP_GPMC_DEBUG and am still able to boot to maemo with no
obvious problems.
So, seems that fixes the problem, feel free to add:
