We should always type-cast pointer to "long" or "unsigned long"
because size of pointer is same as machine word size. This will
avoid pointer type-cast issues on both 32bit and 64bit systems.
This patch fixes pointer type-cast issue in brcmnand_write()
as-per above info.

These really aren't needed, especially now that we embed the soc struct
in our private struct, so we can stash things there if needed.

Use a more descriptive name for the device_node element in struct nand_chip .
This name matches the element name used for device_node property of a flash
in the spi-nor framework.

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.
Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

Remove static in front of ctrl. This variable should not be shared
between different instances of brcmnand_probe(), it should be local to
this function and stored on the stack.

The caller already adds a new line and in the other cases there is no

There are a few small hooks required for chips like BCM63138 and the
iProc family. Let's introduce those now.

BCM7xxx chips are supported entirely by the library code, since they use
generic irqchip interfaces and don't need any extra SoC-specific
configuration.

This core originated in Set-Top Box chips (BCM7xxx) but is used in a
variety of other Broadcom chips, including some BCM63xxx, BCM33xx, and
iProc/Cygnus. It's been used only on ARM and MIPS SoCs, so restrict it
to those architectures.
There are multiple revisions of this core throughout the years, and
almost every version broke register compatibility in some small way, but
with some effort, this driver is able to support v4.0, v5.0, v6.x, v7.0,
and v7.1. It's been tested on v5.0, v6.0, v6.1, v7.0, and v7.1 recently,
so there hopefully are no more lurking inconsistencies.
This patch adds just some library support, on which platform drivers can
be built.
