All linux kernels after v2.6 require a page-aligned location of
an external init ramdisk. Enable CONFIG_SYS_BOOT_RAMDISK_HIGH to
support this with the generic U-Boot relocation code.

Some versions of the Zynq first stage boot loader enable PCAP loopback
during boot regardless of whether or not the boot image includes PL
configuration. This behavior only appears in certain boot modes (notably
QSPI boot). Attempting to configure the PL with the loopback bit set
will result in timeouts and will prevent successful configuration.
In order to avoid this problem, and to avoid dependency on the version
of the FSBL used to boot the system, ensure that the loopback enable bit
is cleared when loading the driver.

U-Boot does not compile for the adp-ag101 boards since
commit a8f9cd1893bef05b92f63242228607b45821c4a7
(net: update FTGMAC100 for MMU/D-cache support)
The driver assumes that the DMA allocation API are provided by all
architectures. This is not the case for nds32 and it causes a
build error. This patch adds DMA allocation API to avoid the errors.

In case only the CONFIG_SYS_I2C_SPEED is set in configuration file,
the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED.
The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver.
Unfortunatelly, due to a typo in the driver, instead of defining
CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined
and therefore the driver failed to compile. The same applies for
CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well.
This patch fixes the issue.

This brings U-Boot's cpp invocation into line with the way the Linux
kernel invokes cpp on device trees. Consistency will be useful to ensure
*.dts is portable between the two.
-undef also has the added advantage of not defining "linux", so DT
property names such as "linux,keymap" don't get mangled.

*.dts may use #include (via cpp) or /include/ (via dtc; assuming a newer
dtc). The choice is up to the creator of the DT. Create a common variable
DTC_INCDIRS that lists the paths searched by include statements, and
update cpp and dtc invocation to use them.
For cpp, also specify -nostdinc to ensure the same set of paths is
available to both type of include statement.
For dtc, create a new DTC_FLAGS variable to hold all the flags passed to
dtc.

The invocation of dtc is significantly more complex that it could be,
in order to work around an issue on old versions of dtc, which print
a message to stdout every time they run.
Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.
Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,
allowing it to be easily inspected.
Assuming a new enough dtc (which an earlier patch enforces), dtc will
parse #line directives in its input file, and generate correct file and
line numbers in error messages, even though cpp is unconditionally
applied to its input file.

board.c:235:3: warning: passing argument 1 of 'simple_strtoul' makes pointer from integer without a cast [enabled by default]
include/vsprintf.h:27:7: note: expected 'const char *' but argument is of type 'unsigned int'

The function return from P_FUNCT2MUX(per) takes 2 bits, however
for BF537_FAMILY with offset != 1 the function is 1 bit.
Also has small refactor for better readability.
In portmux_setup(), it looks odd having "muxreg &= ~(3 << 1);"
while in current code we do muxreg |= (function << offset);.

This commit adds some prototypes into include/mtd/cfi_flash.h.
These functions are defined with a weak attribute in
drivers/mtd/cfi_flash.c.
This means they can be overrided by board-specific ones
if necessary.
When defining such functions under board/ directory or
somewhere, cfi_flash.h should be included.
This makes sure that board-specfic cfi functions
are defined in a correct prototype.

Fixes NFS root problems with Beagle (3530 ES1.0) when used with
external USB-ethernet adapter and "USB start" command used within
u-boot.
Soft resetting the UHH module causes instability issues on
all OMAPs so we just avoid it.
See OMAP36xx Errata
i571: USB host EHCI may stall when entering smart-standby mode
i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock
On OMAP4/5, soft-resetting the UHH module can put it into
Smart-Idle mode and lead to a deadlock.
On OMAP3 this doesn't seem to be the case but still instabilities
are observed on beagle (3530 ES1.0) if soft-reset is used.
e.g. NFS root failures with Linux kernel.
