This is nonportable and wastes a lot of memory and thus should be replaced with
a prober solution asap.

This patch fixes a bug where the TS might stop working after suspend/resume.
This patch is under upstream review and it seems it will change a lot.

Without this patch we cannot make the s3c2410/s3c2440 touchscreen
driver work. This will be done in a different way in upstream kernel.
We specify the delay value (S3C2410_ADCDLY).

This patch adds a flag to the s3c2410_nand platform data, which configures
whether hardware ecc is used for that chip.
Currently hardware ecc is used if it was compiled into the kernel. But if you
want to build a kernel which runs on multiple devices you might have a
configuration where you have devices which require hw ecc as well as devices
which want software ecc.

Early verions off uboot used for the gta02 flashed the nand with ecc information
incompatible to s3c2442 hardware ecc. Disable hardware error correction by
default, unless the bootloader explicitly enables it.

The gta02 uses the glamo mfd driver which requires 9 board irqs.

Some boards have a need for a set of extra IRQ numbers, for example some
multifunction devices which do irq demultiplexing require them.
This patch adds S3C2410_BOARD_NR_IRQS which specifies the number of extra board
IRQs. Board specific code would use S3C2410_BOARD_IRQ_START to get the number of
it's first irq.
Since it is possible to support a multiple boards with a single kernel and
there is no easy way to set a CONFIG option to multiple values and only use the
maximum each board which needs board IRQs has do be explicitly added to irqs.h

On hardware revision 5 and earlier the leds found on the gta02 are missing a
resistor and reading their gpio pin status will always return 0. So we have to
shadow the led states in software. This is done by "hijacking" the gpio accessor
functions for bank B.

The gta02 has three leds which are connected though gpio pins and thus can get
supported by using the generic leds-gpio driver.

This patch fixes a null pointer exception caused by removal of
'ack()' for level interrupts in the Xilinx interrupt driver. A recent
change to the xilinx interrupt controller removed the ack hook for
level irqs.

Functions invoked early when booting up a cpu can't use
tracing because mcount requires a valid 'current_thread_info()'
and TLB mappings to be setup.
The code path of sun4v_register_mondo_queues --> register_one_mondo
is one such case. sun4v_register_mondo_queues already has the
necessary 'notrace' annotation, but register_one_mondo does not.
Normally register_one_mondo is inlined so the bug doesn't trigger,
but with some config/compiler combinations, it won't be so we
must properly mark it notrace.
While we're here, add 'notrace' annoations to prom_printf and
prom_halt so that early error handling won't have the same problem.
