Simon Glass <sjg@chromium.org> says:
This series continues refactoring the bootm code to allow it to be used
with CONFIG_COMMAND disabled. The OS-handling code is refactored and
a new bootm_run() function is created to run through the bootm stages.
This completes the work.
A booti_go() function is created also, in case it proves useful, but at
last for now standard boot does not use this.
This is cmdd (part d of CMDLINE refactoring)
It depends on dm/bootstda-working
which depends on dm/cmdc-working
Adjust boot_os_fn to use struct bootm_info instead of the separate
argc, argv and image parameters. Update the handlers accordingly. Few
of the functions make use of the arguments, so this improves code size

The Andes PLMT driver directly accesses the mtime MMIO region,
indicating its intended use in the M-mode boot stage. However,
since U-Boot proper (S-mode) also uses the PLMT driver, we need
to specifically mark the region as readable through PMPCFGx (or
S/U-mode read-only shared data region for Smepmp) in OpenSBI.
Granting permission for this case doesn't make sense. Instead,
we should use the generic RISC-V timer driver to read the mtime
through the TIME CSR. Therefore, we add the SPL_ANDES_PLMT_TIMER
config, which ensures that the PLMT driver is linked exclusively
against M-mode U-Boot or U-Boot SPL binaries.
