Unlike most configuration options defining this actually disables
support for a feature (parallel flash). Eventually the logic behind this
should probably be flipped so that '#ifndef CONFIG_SYS_NO_FLASH' becomes
'#ifdef CONFIG_HAS_PARALLEL_FLASH' but for now lets document the
existing behaviour.Signed-off-by: Chris Packham

DRA7/AM57xx devices can be operated in many different configurations.
When the SoC is supposed to support a configuration where low power mode
state may involve the SoC completely powered off and DDR is in self
refresh, SoC EMIF controller should not be the master of the reset
signal and an external entity might be in control of things.The default configuration of Linux on TI evms involve not powering off
the voltage rails (due to various reasons including reliability concerns)
and must not allow DDR reset to be controlled by EMIF. On platforms
where external entity might control the reset signal, this configuration
will be a "dont care".Fixes: 536d87470869 ("ARM: DRA7: Update DDR IO registers")

This introduces the part start and part size sub-commands. The purpose of these
is to store the start block and size of a partition in a variable, given the
device and partition number.This allows reading raw data that fits a single partition more easily.
For instance, this could be used to figure out the start block and size of a
kernel partition when a partition table is present, given the partition number.Signed-off-by: Paul Kocialkowski

This allows using only one of either raw or fs mode for SPL mmc boot, without
the need to have provisions for the other. In particular, a device may have
U-Boot installed on a file system on the mmc, without ever needing to read
U-Boot from raw memory. Thus, there is no reason to provide a sector or
partition for raw mode. This allows this behaviour and still provides a robust
fallback mechanism in case provisions for both modes are defined.Signed-off-by: Paul Kocialkowski

When building tools-only (or env) we need to be sure that we do use

problems such as running 'make defconfig' or 'make sandbox_config' and
then 'make tools-only'.Based on the responses below to the thread add linux/kconfig.h higher in
the includes and drop the now unneeded autoconf.h lower down to ensure
the default environment is included correctlyhttp://lists.denx.de/pipermail/u-boot/2015-June/216849.html

The MSI Primo 81 is an Allwinner A31s-based tablet on which the
OTG port is the only accessible USB interface. The existing
defconfig had VGA console on the LCD enabled, but was missing
keyboard support because the prerequisites for that (sunxi MUSB
support and AXP221 GPIO support) had not been available before.
All previously missing dependencies are available now, so this
patch enables keyboard support and its prerequisites in the
defconfig.Signed-off-by: Karsten Merker

Fully resetting the controller is a too big hammer, and the musb_core will
then afterwards fail to communicate with any endpoints other then 0 as
too much state was cleared.Instead report vbus low for 200ms which will effectively end the current

We almost always use UBIFS for user accessible NAND file systems and
the UBIFS file system might contain more than one volume within the
single NAND partition. The last NAND partition is therefore more
appropriately named as "NAND.file-system" instead of "NAND.rootfs"The Linux kernel (as of v3.16) also uses "NAND.file-system" to name the
last NAND partition. This patch makes the partition name consistent
