2015-04-16x86: Add support for panther (Asus Chromebox)Simon Glass
Support running U-Boot as a coreboot payload. Tested peripherals include: - Video (HDMI and DisplayPort) - SATA disk - Gigabit Ethernet - SPI flash USB3 does not work. This may be a problem with the USB3 PCI driver or something in the USB3 stack and has not been investigated So far this is disabled. The SD card slot also does not work. For video, coreboot will need to run the OPROM to set this up. With this board, bare support (running without coreboot) is not available as yet. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-04-16x86: Support machines with >4GB of RAMSimon Glass
Some systems have more than 4GB of RAM. U-Boot can only place things below 4GB so any memory above that should not be used. Ignore any such memory so that the memory size will not exceed the maximum. This prevents gd->ram_size exceeding 4GB which causes problems for PCI devices which use DMA.

2015-03-28malloc_f: enable SYS_MALLOC_F by default if DM is onMasahiro Yamada
This option has a bool type, not hex. Fix it and enable it if CONFIG_DM is on because Driver Model always requires malloc memory. Devices are scanned twice, before/after relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc memory before relocation. As it is board-independent, handle it globally.
