Unlike the other patches in this series so far, this commit fixes a
ambiguity in the license terms for some OMAP files: the code was
originally derived from the Linux kernel sources, where it was clearly
marked as GPL-2.0 (i. e. without the "or later" part), but the U-Boot
version had a GPL-2.0+ file header added, apparently without
permission / relicensing from the original authors of the code.
Insert a GPL-2.0 SPDX-License-Identifier to fix this.

Setting the direction and an output value should be done by
First, set the desired output value.
Then, switch to output.
If this is done in the inverse order, like at the moment,
there can be a glitch on the GPIO line while switching first
the old output value and aftwards the new one.
Fix this by inverting the order of the direction/set_value
calls.

The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs.
These SoCs have different gpio count but currently omap_gpio driver uses hard
coded 192 which is wrong.
This patch fixes this issue by:
1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h.
2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5.
Thanks for Lubomir Popov to provide valuable comments to fix this issue.

The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx.
A lot of machine macros are used to accomodate both code in one gpio driver.
This patch split the old gpio driver and move new gpio2 support to the generic
gpio driver folder.
- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's
config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while the
older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.
- All blackfin specific gpio function names are replaced by the generic gpio APIs.

Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.
Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.
There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.
Adding several gpios IP is also possible and supported.
For listing gpio configuration please use "gpio status" command
This patch also remove one compilation warning:
microblaze-generic.c: In function 'do_reset':
microblaze-generic.c:38:47: warning: operation on '*1073741824u'
may be undefined [-Wsequence-point]

In master we had already taken a patch to fix the davinci GPIO code for
CONFIG_SOC_DM646X and in u-boot-ti we have additional patches to support
DA830 (which is CONFIG_SOC_DA8XX && !CONFIG_SOC_DA850). Resolve these
conflicts manually and comment the #else/#endif lines for clarity.

We can generally trust the ICH to have GPIO Bank 0 (the first 32 pins) in the
same place across all versions. This change adds two more banks, for up to
96 GPIOS.
BUT:
- Not all chipsets have the same number of GPIOs
- Not all chipsets have the same number of GPIO banks
- Not all chipsets put the additional banks at the same offset from GPIOBASE
- There so many chipset variants that it's pretty much impossible to support
them all, or even keep track of the new ones.
So, although this adds suppport for the additional banks that seem to work
for the particular variants of CougarPoint Mobile chipsets that we've tried,
there's no chance it will support everything Intel produces. Good luck.

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.
All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

gpio_get_value() should use PSR like Linux, not DR, because DR does not always
reflect the pin state, while PSR does. This is especially useful to detect a
short circuit on a GPIO pin configured as output, or to read the level of a pin
controlled by a non-GPIO IOMUX function.

This SoC is used in the Raspberry Pi, for example.
For more details, see:
http://www.broadcom.com/products/BCM2835
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf.
Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.
