(1 means no Vbus voltage sensed, 0 means Vbus voltage

Change the halt and reboot method from gpio based to "jump
to ROM IPL beginning". This gives control back to IPL, which
without PowerOn key pressed, will put the device into deep
sleep until PowerOn is pressed for 1 second.

But this has the benefit of keeping the RTC registers across
reboots, which is good for OS change.

Since mioa701 board has migrated to the mfp architecture,
low power gpio setup is now correctly handled even when gpio
led driver is not loaded, and leds and vibrator don't stay
activated in suspend mode (especially vibrator).

This patch implements Eric Miao's idea to detect the correct value of
sdram_rows by inspecting the MDCNFG register settings.
It is only tested on two pxa27x devices with 64MB RAM (magician and
hx4700) so far.

Following the removal of the "->policy" usage for PXA255 in patch
459fc208 (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.

It also cures the runtime warning that was printed each time the
frequency was changed.

Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked
with the run/turbo thing.

Tested on an Arcom/Eurotech Viper.

The optimal change would be to move the AC97 register definitions into
the AC97 driver, unfortunately, the registers are shared between several

Original patch from Marek Vasut, the problems with PXA26x are:

1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
   inverted in GPDR2, as well as their alternate function bits being
   '1' for their GPIO functionality in GAFRx

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.

__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

This reverts commit da1a3dc0.

The originally proposed way in the above commit is incorrect. And
there is no easy way to distinguish between pxa25x and pxa26x at

The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we
already have that variable, remove the unnecessary 'gpio_nr' now.

Also, fix the incorrect GPIO number passed in pxa27x_init_irq().

Note: pxa_last_gpio should be initialized earlier, and this is true
since it's been assigned in machine_desc->init_irq().

The original incorrect configuration caused GPIO79_nCS_3 being overriden,
thus resulted in the NAND flash not being detected. The real PSKTSEL pin
