[U-Boot] [PATCH 07/11] MIPS: bootm: add support for generic relocation of init ramdisks

Sun Jun 9 00:42:46 CEST 2013
All linux kernels after v2.6 require a page-aligned location of
an external init ramdisk. Enable CONFIG_SYS_BOOT_RAMDISK_HIGH to
support this with the generic U-Boot relocation code.
