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.
