Currently armv7m_load_kernel() takes the size of the block of memory
where it should load the initial guest image, but assumes that it
should always load it at address 0. This happens to be true of all
our M-profile boards at the moment, but it isn't guaranteed to always
be so: M-profile CPUs can
Two small patches to armv7m_load_kernel(). The first is just getting
rid of some dead code, that I noticed while working on the function.
The second is to make boards pass armv7m_load_kernel() the base
address for loading guest (non-ELF) binaries. At the moment we
assume all M-profile boards
Arm system emulation targets always have TARGET_BIG_ENDIAN clear, so
there is no need to have handling in armv7m_load_kernel() for the
case when it is defined. Remove the unnecessary code.
Side notes:
