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. | |
3 | # | |
4 | # Author: Tom Rini <trini@mvista.com> | |
5 | # | |
6 | # Notes: | |
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 | |
18 | # address. | |
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. | |
