11# Notes:
12# (1) All machines must set the END variable to the suffix of the preferred
13# final image (i.e. would be copied in 'make znetboot'.
14# (2) For machine targets which use the mktree program you can optionally
15# set ENTRYPOINT which the image should be loaded at.  The optimal setting
16# for ENTRYPOINT is the link address.
