	 U-Boot kernel load address, the address in physical address space

	 where u-boot will place the Linux kernel before booting it.

	 This address is normally the base address of main memory + 0x4000.



config UBOOT_FLASH_ADDR

	default 0x00080000

	---help---

	 Optional setting only affecting the uImage.o ELF-image used to

	 download the uImage file to the target using a ELF-loader other than

	 U-Boot. It may for example be used to download an uImage to FLASH with

	 the GRMON utility before even starting u-boot.



config UBOOT_ENTRY_ADDR

	hex "uImage Entry Address"

	default 0xf0004000

	---help---

	 Do not change this unless you know what you're doing. This is

	 hardcoded by the SPARC32 and LEON port.



	 This is the virtual address u-boot jumps to when booting the Linux

	 Kernel.
