[U-Boot] [PATCH v3 5/7] boot: change some arch ifdefs to feature ifdefs

Wed Oct 13 21:57:35 CEST 2010
The routines boot_ramdisk_high, boot_get_cmdline and boot_get_kbd
are currently enabled by various combinations of CONFIG_M68K,
CONFIG_POWERPC and CONFIG_SPARC.
Use CONFIG_SYS_BOOT_<FEATURE> defines instead.
CONFIG_SYS_BOOT_RAMDISK_HIGH
CONFIG_SYS_BOOT_GET_CMDLINE
CONFIG_SYS_BOOT_GET_KBD
Define these as appropriate in arch/include/asm/config.h files.
