There's no need to have this file in plat/fpga.h. We can
make it local to plat-omap replacing fpga_read/write
functions directly with readb/writeb as that's how
they are already defined in fpga.h.

Note that 2420 based H4 is also using the fpga, so let's
keep the led support around in plat-omap until we flip
over mach-omap2 to device tree.

We are moving omap2+ to use the device tree based pinctrl-single.c
and will be removing the old mux framework. This will remove the

Note that mach-omap1 uses struct plat_serial8250_port

Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart
and OMAP_TAG_UART. This works for mach-omap2, but causes issues on
mach-omap1 for some boards as the mach-omap1 serial.c was muxing
pins based on the enabled_uart flag for 15xx.

Fix this by muxing pins in board-*.c files for the 15xx boards for
the uart ports that had enabled_uart flag set before the commit
above.

Tested on Amsdtrad Delta only.

Note that in the future we should add support for powering down
the uarts with a timer like mach-omap2/serial.c does. Otherwise
the enabled uarts will be blocking retention-while-idle.

Background: with new UART idle code, all on-chip UARTs are idled using

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies

these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places

DMA to, or physical addresses are thrown through a virtual to physical

Some ARM platforms have the ability to program the interrupt controller to
detect various interrupt edges and/or levels. For some platforms, this is
critical to setup correctly, particularly those which the setting is dependent
on the device.

Currently, ARM drivers do (eg) the following:

err = request_irq(irq, ...);

set_irq_type(irq, IRQT_RISING);

However, if the interrupt has previously been programmed to be level sensitive
(for whatever reason) then this will cause an interrupt storm.

Hence, if we combine set_irq_type() with request_irq(), we can then safely set
the type prior to unmasking the interrupt. The unfortunate problem is that in
order to support this, these flags need to be visible outside of the ARM
architecture - drivers such as smc91x need these flags and they're
cross-architecture.

Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the
property that the device would like. The IRQ controller code should do its
best to select the most appropriate supported mode.
