1 # This is far from simple, but I couldn't think of a good name. This is
2 # for making the 'zImage' or 'zImage.initrd' on a number of targets.
4 # Author: Tom Rini <trini@mvista.com>
7 # (1) For machines that do not want to use the ELF image directly (including
8 # stripping just the ELF header off), they must set the variables
9 # zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target
10 # that produces the desired image and they must set end-$(CONFIG_MACHINE)
11 # to what will be suffixed to the image filename.
12 # (2) Regardless of (1), to have the resulting image be something other
13 # than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for
14 # the zImage, znetboot, and znetbootrd targets.
15 # (3) For machine targets which use the mktree program, you can optionally
16 # set entrypoint-$(CONFIG_MACHINE) to the location which the image should be
17 # loaded at. The optimal setting for entrypoint-$(CONFIG_MACHINE) is the link
19 # (4) It is advisable to pass in the memory size using BI_MEMSIZE and
20 # get_mem_size(), which is memory controller dependent. Add in the correct
21 # XXX_memory.o file for this to work, as well as editing the
22 # misc-$(CONFIG_MACHINE) variable.
