The RTL8211B_driver structure in drivers/net/phy/realtek.c contains a
wrong PHY ID (0x1cc910 instead of 0x1cc912) in the uid field.
The lowest four bits of the PHY ID encode the chip revision (B+C/D/E/F)
of the RTL8211 and the code originally applied a mask of 0xfffff0 to
the PHY ID, so that matching the PHY ID to the appropriate driver code
was only done on the chip type (RTL8211), but not on a specific
revision.
After introduction of support for the RTL8211E, which needed another
startup function than the older chip revisions, commit
4220504767 changed the mask to 0xffffff
to make the chip revision relevant for the match, but didn't provide
the now-relevant lower bits of the uid field for the RTL8211B/C.
Fix this by setting the full PHY ID in the RTL8211B_driver uid field.

Add a block device cache to speed up repeated reads of block devices by
various filesystems.
This small amount of cache can dramatically speed up filesystem
operations by skipping repeated reads of common areas of a block
device (typically directory structures).
This has shown to have some benefit on FAT filesystem operations of
loading a kernel and RAM disk, but more dramatic benefits on ext4
filesystems when the kernel and/or RAM disk are spread across
multiple extent header structures as described in commit fc0fc50.
The cache is implemented through a minimal list (block_cache) maintained
in most-recently-used order and count of the current number of entries
(cache_count). It uses a maximum block count setting to prevent copies
of large block reads and an upper bound on the number of cached areas.
The maximum number of entries in the cache defaults to 32 and the maximum
number of blocks per cache entry has a default of 2, which has shown to
produce the best results on testing of ext4 and FAT filesystems.
The 'blkcache' command (enabled through CONFIG_CMD_BLOCK_CACHE) allows
changing these values and can be used to tune for a particular filesystem
layout.

ulpi_read and ulpi_write are used to read/write registers via ULPI bus.
Code generates compilation warnings on 64-bit machines where pointer
is cast to u32.
This patch drops all but last 8 bits of register address.
It is possible, because addresses on ULPI bus are 6- or 8-bit.
It is not possible (according to ULPI 1.1 spec) to have more
than 8-bit addressing.
This patch should not cause regressions as all calls to
ulpi_read/write use either structure pointer (@ address 0) or integer
offsets cast to pointer - addresses requested are way below 8-bit range.
