2015-08-13kconfig: add config option for shell promptNikita Kiryanov293-0/+294
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.

2015-08-13ARM: drop "optional" from target select in favor of ARCH_VERSATILEMasahiro Yamada3-3/+0
Since commit a26cd04920dc ("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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2015-08-13ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.Peter Griffin1-0/+5
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.

The LG Optimus Black (P970) codename sniper is a smartphone that was designed and manufactured by LG Electronics (LGE) and released back in 2011. It is using an OMAP3630 SoC GP version, which allows running U-Boot and the U-Boot SPL from the ground up. This port is aimed at running an Android version such as Replicant, the fully free Android distribution. However, support for upstream Linux with device-tree and common GNU/Linux distros boot commands could be added in the future.

Now that the SPL structure is organised such that it matches the U-Boot's SPL design, it is possible to use the option of relocating GD to RAM. And since we have GD in RAM, move malloc area to RAM as well. We point the malloc base pointer 1 MiB past U-Boot's load address.

2015-08-06x86: Enable debug UART for MinnowmaxSimon Glass1-0/+4
Enable the debug UART and emit a single 'a' early in the init sequence to show that it is working. Unfortunately the debug UART implementation needs a stack to work. I cannot seem to remove this limitation as the absolute 'jmp %eax' instruction goes off into the weeds. So this means that the character output cannot be any earlier than car_init_ret, where memory is available for a stack.

2015-08-06dm: cros_ec: Convert the I2C tunnel code to use driver modelSimon Glass2-0/+4
The Chrome OS EC supports tunnelling through to an I2C bus on the EC. This currently uses a copy of the I2C command code and a special 'crosec' sub-command. With driver model we can define an I2C bus which tunnels through to the EC, and use the normal 'i2c' command to access it. This simplifies the code and removes some duplication. Add an I2C driver which tunnels through to the EC. Adjust the EC code to support binding child devices so that it can be set up. Adjust the existing I2C xfer function to fit driver model better. For now the old code remains to allow things to still work. It will be removed in a later patch once the new flow is fully enabled. Signed-off-by: Simon Glass <sjg@chromium.org>

Secure Boot Target is added for NAND for P3041. For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC. In case of secure boot, this default address maps to Boot ROM. The Boot ROM code requires that the bootloader(U-boot) must lie in 0 to 3.5G address space i.e. 0x0 - 0xDFFFFFFF. In case of NAND Secure Boot, CONFIG_SYS_RAMBOOT is enabled and CPC is configured as SRAM. U-Boot binary will be located on SRAM configured at address 0xBFF00000.
