V2:
Add R-b/A-b tag
Drop inaccurate comment in patch 1

i.MX DSP firmware has segments with PT_LOAD and memsz/filesz as zero.
It is valid case the memsz set to zero according to elf spec:
https://refspecs.linuxbase.org/elf/elf.pdf page 40

So we could let remoteproc elf loader handle this case, then no
duplicate code in imx dsp rproc driver

Tested i.MX8MP DSP and M7 remoteproc

Peng Fan (2):
remoteproc: elf_loader: skip segment with memsz as zero
remoteproc: imx_dsp_rproc: use common rproc_elf_load_segments
