  warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Fix by casting it with uintptr_t.

43a2183928 cache: add sifive composable cache driver
This driver is currently responsible for enabling all ccache ways.
Composable cache could be configure as RAM or cache, we will use it as
RAM at the beginning to put the u-boot SPL there. In u-boot proper
phrase, we will use the composable cache as cache, and try to enable the
cache ways.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

d1998a9fde dm: treewide: Rename ofdata_to_platdata() to of_to_plat()
This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

db41d65a97 common: Move hang() to the same header as panic()
At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

88ebf5830f dm: cache: add the pl310 cache controller driver
Add a PL310 cache controller driver that is usually found on
ARMv7(32-bit) devices. The driver configures the cache settings that can
be found in the device tree files.

This initial revision only configures basic settings(data & instruction
prefetch, shared-override, data & tag latency). I believe these are the
settings that affect performance the most. Comprehensive settings can be
done by the OS.
