7a3e70cfd8 fs/fs.c: read up to EOF when len would read past EOF
http://lists.denx.de/pipermail/u-boot/2012-September/134347.html
allows for reading files in chunks from the shell.

When this feature is used to read past the end of a file an error
was returned instead of returning the bytes read up to the end of
file. Thus the following fails in the shell:

offset = 0
len = chunksize
do
	read file, offset, len
	write data
until bytes_read < len

The patch changes the behaviour to printing an informational
message and returning the actual read number of bytes aka read(2)
behaviour for convenient use in U-Boot scripts.

181bd9dc61 kconfig: add config option for shell prompt
Add option to set shell prompt string from menuconfig and migrate
boards globally.

The migration is done as follows:
- Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the
  entry moved to their defconfig files.
- Boards that defined some kind of #ifdef logic which selects the
  CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT
  right before the #ifdef logic and were left alone.
- This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus
  CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h
  files. This results in a streamlined default value across platforms, and
  includes the following files: spear-common, sunxi-common, mv-common,
  ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common.
- Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were
  not updated in their respective defconfig files under the assumption that
  since they did not explicitly define a value, they're fine with whatever
  the default is.
- On the other hand, boards that relied on a value defined in some
  <boards>_common.h file such as woodburn_common, rpi-common,
  bur_am335x_common, ls2085a_common, siemens_am33x_common, and
  omap3_evm_common, had their values moved to the respective defconfig files.
- The define V_PROMPT was removed, since it is not used anywhere except for
  assigning a value for CONFIG_SYS_PROMPT.

589907e2c1 ARM: drop "optional" from target select in favor of ARCH_VERSATILE
Since commit a26cd04920 ("arch: Make board selection choices
optional"), Kconfig could create such an insane .config file that
no SoC/board is selected.

This is now a real problem for Buildroot, for example.
(http://lists.busybox.net/pipermail/buildroot/2015-July/135125.html)

This commit drops the "optional" from the ARM target select menu
in favor of "Versatile family".

Rationale:
 - Historically, Linux chose versatile_defconfig as the default
   of ARM defconfig. (arch/arm/Makefile of Linux describes:
   KBUILD_DEFCONFIG := versatile_defconfig)

 - It was published by ARM Ltd.

The "method" parameter was part of the original port of the driver from
the kernel.  At some point this may have been added to allow for future
differentiation (as omap1 and omap2 have different GPIO IP blocks, so
this wasn't an unreasonable thing to do).  At this point however it's
just extra overhead, so drop.

11ac236320 ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.
HiKey is the first 96boards consumer edition compliant board. It features a hi6220
SoC which has eight ARM A53 cpu's.

This initial port adds support for: -
1) Serial
2) eMMC / SD card
3) USB
4) GPIO

It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.

Notes:

eMMC has been tested with basic reading of eMMC partition into DDR. I have not
tested writing / erasing. Due to lack of clock control it won't be
running in the most performant high speed mode.

SD card slot has been tested for reading and booting kernels into DDR.
It is also currently configured to save the u-boot environment to the
SD card.

USB has been tested with ASIX networking adapter to tftpboot kernels
into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage
are correctly enumerated.

GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.

095a5ef88e ARM: DRA72: disable workaround for 801819
DRA72x processor variants are single core and it does not export ACP[1].
Hence, we have no source for generating an external snoop requests which
appear to be key to the deadlock in DRA72x design.

Since we build the same image for DRA74x and DRA72x platforms, lets
runtime detect and disable the workaround (in favor of performance) on
DRA72x platforms.
