The fdtdec_find_aliases_for_id() function is complicated enough that
it really should have some tests. This does not necessarily need to be
committed to U-Boot, but it might be useful.(note there are a few minor inconsistencies with this patch which will be
cleaned up when the USB series is applied)Signed-off-by: Simon Glass

Stephen Warren pointed out that we should use nodes whether or not they
have an alias in the /aliases section. The aliases section specifies the
order so far as it can, but is not essential. Operating without alisses
is useful when the enumerated order of nodes does not matter (admittedly
rare in U-Boot).This is considerably more complex, and it is important to keep this
complexity out of driver code. This patch creates a function
fdtdec_find_aliases() which returns an ordered list of node offsets
for a particular compatible ID, taking account of alias nodes.Signed-off-by: Simon Glass

The 4.2.2 gcc in the ELDK42 release doesn't like the direct SP
load using a constant in tegra2_start. Change it to use a load
thru another reg using mov sp, %0 : : "r"(CONST).Tested on my Seaboard T20-A03, U-Boot loads and runs OK. Also
compiled all tegra2 builds with both gcc 4.2.2 and 4.4.1 OK.Signed-off-by: Tom Warren

Ensure that transmit and receive buffers are cache-line aligned.
Invalidate cache for each packet as received, update receive buffer
descriptors one cache line at a time, flush cache before transmitting.Original patch by Marek:

This allows i.MX28 MMC host to fully utilize DMA transfers and caches, greatly

This utilizes the newly introduced bounce buffers in the MMC layer.

Cc: Fabio Estevam -
This implements generic bounce buffer at the end of MMC command submission
chain. Therefore if unaligned data are passed, they are copied. This stuff
should be pushed down into the MMC subsystem to squash all places generating
these unaligned data.Signed-off-by: Marek Vasut

commit 72fa467988e7944407a634ddc4bc6a2df685c04c moved atmel_mci_init() into
include/atmel_mci.h. Some AT91 boards are also using this interface and need
to include atmel_mci.h now.This patch fixes MAKEALL complaints like this:

- change CONFIG_ENV_RANGE to contain 2 nand erase blocks,
one for bad block reserve.
- remove from the envvariable "img_writeramdisk" the
ubifsmount command, as it is not needed.
- erase the hole mtd partition containing u-boot
- save environment variable "dvn_app_vers" and "dvn_boot_vers"
only after installing the new image.

twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively
enabling the supply), and only then sets vsel (selects voltage). This could
lead to wrong voltage for a short time, or even long time if second i2c
write fails.Fix this by writing vsel first and device group after that. Also
introduce error checking to not enable the supply if we failed to set
the voltage, and start logging errors as power supply problems are
usually important.Signed-off-by: Grazvydas Ignotas
