RISC-V: Remove mem_end command line processing (5d44bf20) · Commits · 戴 / test

This is just some cruft left over from before the port converted to device tree. The right way to handle memory regions is to specify them in the device tree, which BBL (our simplest bootloader) is already capable of doing. This patch simply removes the cruft. Signed-off-by:
