Rather than repeat the line
 #if defined(CONFIG_TIMESTAMP) || defined(CONFIG_CMD_DATE) || \
defined(USE_HOSTCC)

everywhere, put this in a header file and #define IMAGE_ENABLE_TIMESTAMP
to either 1 or 0. Then we can use a plain if() in most code and avoid

libfdt: Add fdt_next_subnode() to permit easy subnode iteration

Iterating through subnodes with libfdt is a little painful to write as we
need something like this:

for (depth = 0, count = 0,
offset = fdt_next_node(fdt, parent_offset, &depth);
     (offset >= 0) && (depth > 0);
     offset = fdt_next_node(fdt, offset, &depth)) {
if (depth == 1) {
/* code body */
}
}

Using fdt_next_subnode() we can instead write this, which is shorter and
easier to get right:

for (offset = fdt_first_subnode(fdt, parent_offset);
     offset >= 0;
     offset = fdt_next_subnode(fdt, offset)) {
/* code body */
}

Also, it doesn't require two levels of indentation for the loop body.

OCR (operation conditions register).  To decouple this polling loop,
device init is split into two parts: The first part fires the OCR query
command, and the second part polls the result.  So the caller is now no
longer bound to the OCR-polling delay; he may fire the query, go
somewhere and then come back later for the result.

To use this, call mmc_set_preinit() on any device which needs this.

This can save significant amounts of time on boot (e.g. 200ms) by

powerpc/85xx: set USB2 default mode to 'device' for (super)hydra boards

The Hydra and Superhydra (P3041DS, P5020DS, and P5040DS) boards have a
second USB port that can be configured in either host, peripheral (aka
device), or OTG (on-the-go) mode.  When configured in host mode, if
the port is connected to another USB host, damage to the board can
occur.

To avoid this, we change the default setting to peripheral mode.  Ideally,
we'd set it to OTG mode, but currently there is no OTG support for
these boards.

Setting the hwconfig variable will also update the device tree, and so
Linux will configure the port for peripheral mode as well.

powerpc/p1_p2_rdb_pc: Add a pin to reset the DDR chip for P1021RDB-PC

When P1021RDB-PC reboot system, the board will hung at uboot DDR
configuration. For P1021RDB-PC DDR reset pin is multiplex with
QE, so uboot will reserve this pin for QE and skip DDR reset.
Other platforms without QE will do this reset. This patch adds
a slight code to reset DDR chip by QE CE_PB8 pin for NAND and
NOR FLASH boot. For booting from SPI FALSH and SD card, it
seems possible to use the rom on chip to write to the GPIO
pins before configuring the DDR.
