For freescale i.MX53 eSDHCv2, when using CMD12, cmdtype need
to be set to ABORT, otherwise, next read command will hang.
This is a software Software Restrictions in i.MX53 reference manual:
29.7.8 Multi-block Read
For pre-defined multi-block read operation, that is,the number of blocks
to read has been defined by previous CMD23 for MMC, or pre-defined number
of blocks in CMD53 for SDIO/SDCombo,or whatever multi-block read without
abort command at card side, an abort command, either automatic or manual
CMD12/CMD52, is still required by ESDHC after the pre-defined number of
blocks are done, to drive the internal state machine to idle mode. In this
case, the card may not respond to this extra abort command and ESDHC will
get Response Timeout. It is recommended to manually send an abort command
with RSPTYP[1:0] both bits cleared.

Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

There seems to be tools producing incorrect 'end of bitmap data'
markers '0100' in a RLE bitmap. Drawing such bitmaps can result
in overwriting memory above the frame buffer. E.g. on MPC5121e
based boards this memory can contain U-Boot environment.
We may not rely on the correct end of bitmap data marker 0001
only, but also have to check whether we are going to draw a
valid frame buffer scan line.
The patch provides a fix by maintaining a pixel counter
which is incremented by the amount of pixels we are going
to draw. If the counter exceeds frame buffer pixels limit
we stop the drawing with the error message.

The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

The tsec driver had a bunch of PHY drivers already written. This
converts them all into PHY Lib drivers, and serves as the first
set of PHY drivers for PHY Lib.
While doing that, cleaned up a number of magic numbers (though
not all of them, as PHY vendors like to keep their numbers as
magical as possible). Also, noticed that almost all of the
vitesse/cicada PHYs had the same config/parse/startup functions,
so those have been collapsed into one.

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)
We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.
We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,
we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

There were a few files which were already using phy_read and phy_write

Also, uec_phy.c had a marvell_init function which I renamed to not

mtd: nand: rearrange ONFI revision checking, add ONFI 2.3
In checking for the ONFI revision, the first conditional (for checking
"unsupported" ONFI) seems unnecessary. All ONFI revisions should be
backwards-compatible; even if this is not the case on some newer ONFI
revision, it should simply fail the second version-checking if-else block
(i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we
move our "unsupported" condition after having checked each bit field.
Also, it's simple enough to add a condition for ONFI revision 2.3. Note
that this does *NOT* mean we handle all new features of ONFI versions
above 1.0.

The omap24xx driver only seems to support devices that have a single subaddress
byte. With these types of devices, the first access in a bus transaction is
usually a write (writes the subaddress) followed by either a read or write to
access the devices registers.
Many such devices will respond to a read as the first access, but there are at
least some that will NACK such a read. (e.g. ADV7180.)
The probe function attempts to detect a devices ACK to a read access only and
fails to find devices that NACK a read.
This commit modifies the probe function to start a write instead. This detects
devices that respond to reads (since they must also respond to writes) as well
as those that only respond to writes. The bus is immediately set to idle after a
(N)ACK avoiding actually writing anything to the device.
