2017-02-07net: cosmetic: Make the MAC address string less magicaloliver@schinagl.nl
In u-boot printf has been extended with the %pM formatter to allow printing of MAC addresses. However buffers that want to store a MAC address cannot safely get the size. Add a define for this case so the string of a MAC address can be reliably obtained. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2017-02-07net: cosmetic: Do not use magic values for ARP_HLENoliver@schinagl.nl
Commit 674bb249825a ("net: cosmetic: Replace magic numbers in arp.c with constants") introduced a nice define to replace the magic value 6 for the ethernet hardware address. Replace more hardcoded instances of 6 which really reference the ARP_HLEN (iow the MAC/Hardware/Ethernet address).

2017-02-07x86: make LOAD_FROM_32_BIT visible for platformsAndy Shevchenko
This option is useful not only for development, but for the platforms where U-Boot is run from custom ROM bootloader. For example, Intel Edison is that board.

2017-02-07x86: qemu: Add a config for 64-bit U-BootBin Meng
Add a new board config which uses 64-bit U-Boot. Supported features are the same as the other 64-bit board (Google Chromebook Link). It is a start for us to test 64-bit U-Boot easily without the need to access a real hardware. Note CONFIG_SPL_ENV_SUPPORT is required for QEMU 64-bit as without this the SPL build fails at the end. This is just a workaround as CONFIG_SPL_ENV_SUPPORT is not needed at all. common/built-in.o:(.data.env_htab+0xc): undefined reference to 'env_flags_validate' lib/built-in.o: In function `hsearch_r': lib/hashtable.c:380: undefined reference to 'env_callback_init' lib/hashtable.c:382: undefined reference to 'env_flags_init' make[1]: *** [spl/u-boot-spl] Error 1 Except those SPL options required by 64-bit, compared to 32-bit config, the following options are different: - CONFIG_SYS_MALLOC_F_LEN has to be increased to 0x1000 for SPL. - CONFIG_DEBUG_UART has to be included due to the weird issue. See TODO comments in arch/x86/cpu/x86_64/cpu.c:arch_setup_gd(). Once this issue gets fixed, debug uart can be optional.

Add the correct pre-relocation tag so that the required device tree nodes are present in the SPL device tree. On x86 it doesn't make a lot of sense to have a separate SPL device tree. Since everything is in the same ROM we might as well just use the main device tree in both SPL and U-Boot proper. But we haven't implemented that, so this is a good first step.
