ARM v7: Flush icache when executing a program with go

ARM v7 runs with icache enabled. For reliable results the go command
needs to flush the icache before jumping or it may risk running
cached instructions that differ from what currently is in memory.
mkconfig: Make CONFIG_SYS_BOARD_NAME default to the configured target name

This change makes CONFIG_SYS_BOARD_NAME globally available as the configured
target name, avoiding the need to define manually for boards having multiple
targets sharing the same board implementation.
Makefile: Accept target names in all lower case to ease matching

ARM sunxi: Basic GPIO driver

GPIO driver for Allwinner sun4i/sun5i family of SoCs

GPIO Pins are named by their symbolic pin names P<g><#>
such as PH19 or H19.

Note: This do not perform any validation if the pin is in use
for some other I/O function. Use with care.
tools: mksunixboot adding a Allwinner boot header

This tool adds a boot header to the supplied file, for booting
code directly from the SoC embedded boot rom. Needed for making
the SPL loader bootable.

ARM: sunxi: U-Boot SPL capable of booting directly from MMC

Allwinner sunxi family of SoCs boots from MMC0/NAND/NOR/MMC2 loading
boot code into an embedded 32KB SRAM.

This patch adds support for booting u-boot SPL from MMC0

We first initializes the console UART, then DRAM controller with board
specific DRAM configuration details, configure CPU core voltage and
clocks before loading the full u-boot image into DRAM.
