2015-08-18of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

2015-08-18of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROLMasahiro Yamada
As we discussed a couple of times, negative CONFIG options make our life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ... and here is another one. Now, there are three boards enabling OF_CONTROL on SPL: - socfpga_arria5_defconfig - socfpga_cyclone5_defconfig - socfpga_socrates_defconfig This commit adds CONFIG_SPL_OF_CONTROL for them and deletes CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert the logic.

2015-08-13kconfig: add config option for shell promptNikita Kiryanov
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.

2015-08-05usb: Fix device detection codeMarek Vasut
The code in question polls an USB port status via USB_REQ_GET_STATUS to determine whether there is a device on the port or not. The way to figure that out is to check two bits. Those are wPortChange[0] and wPortStatus[0]. The wPortChange[0] indicates whether some kind of a connection status change happened on a port (a device was plugged or unplugged). The wPortStatus[0] bit indicates the status of the connection (plugged or unplugged). The current code tests whether wPortChange[0] == wPortStatus[0] and if that's the case, considers the loop polling for the presence of a USB device on port finished. This works for most USB sticks, since they come up really quickly and trigger the USB port change detection before the first iteration of the detection loop happens. Thus, both wPortChange[0] and wPortStatus[0] are set to 1 and thus equal. The loop is existed in it's first iteration and the stick is detected correctly. The problem is with some obscure USB sticks, which take some time before they pop up on the bus after the port was enabled. In this case, both the wPortChange[0] and wPortStatus[0] are 0. They are equal again, so the loop again exits in the first iteration, but this is incorrect, as such USB stick didn't have the opportunity to get detected on the bus. Rework the code such, that it checks for wPortChange[0] first to test if any connection change happened at all. If no change occured, keep polling. If a change did occur, test the wPortStatus[0] to see there is some device present on the port and only if this is the case, break out of the polling loop. This patch also trims down the duration of the polling loop from 10s per port to 1s per port. This is still annoyingly long, but there is no better option in case of U-Boot unfortunatelly. This change will most likely increase the duration of 'usb start' on some platforms, but this is needed to fix a bug.

2015-07-27pxe: add AArch64 image supportStephen Warren
The sysboot and pxe commands currently support either U-Boot formats or raw zImages. Add support for the AArch64 Linux port's native image format too. As with zImage support, there is no auto-detection of the native image format. Rather, if the image is auto-detected as a U-Boot format, U-Boot will try to interpret it as such. Otherwise, U-Boot will fall back to a raw/native image format, if one is enabled. My belief is that CONFIG_CMD_BOOTZ won't ever be enabled for any AArch64 port, hence there's never a need to differentiate between CONFIG_CMD_ _BOOTI and _BOOTZ at run-time; compile-time will do. Even if this isn't true, we want to prefer _BOOTI over _BOOTZ when defined, since _BOOTI is definitely the native format for AArch64.
