If a context switch occurs in function omap_wait() just before the while loop is entered, then upon return from context switch the timeout may already have elapsed: in that case, status is never read from NAND device, and omap_wait() returns an error. This failure has been experimentally observed during stress tests. This patch ensures a NAND status read is always performed before returning, as in the generic nand_wait() function.

Some not-supported nand chips may pass the current parsing code, and get the wrong page size and oob size. Sometimes, it's hard to notice that you get the wrong values, because there is no warning or error. So it's useful to print out the page size and oob size in the end of the parsing function. We can check these values with the datasheet of the nand chip as soon as possible.

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

Commit 069d4e74 ("ARM: EXYNOS4: Remove clock event timers using ARM private timers") removed support for local timers and forced to use MCT as event source. However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it. This patch provides a workaround that enables UniversalC210 boards to boot again. s5p-timer is used as an event source, it works only for non-SMP builds.

Fix SMP TWD boot regression on sh73a0 based platforms caused by: 4200b16d ARM: shmobile: convert to twd_local_timer_register() interface After the merge of the above commit it has been impossible to boot sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The kernel crashes at smp_init_cpus() timing which is before the console has been initialized, so to the user this looks like a kernel lock up without any particular error message. This patch fixes the regression on sh73a0 by moving the TWD registration code from smp_init_cpus() to sys_timer->init() time.
