LoongArch: Add FDT booting support from efi system table

Since commit 40cd01a9c324("efi/loongarch: libstub: remove dependency on
flattened DT"), we can parse the FDT from efi system table.

And now, LoongArch is coming to support booting with FDT, so we add the
relevant booting support as well as parameter parsing.

MIPS&LoongArch&NIOS2: adjust prototypes of p?d_init()

MIPS&LoongArch&NIOS2: adjust prototypes of p?d_init()

Patch series "mm/sparse-vmemmap: Generalise helpers and enable for
LoongArch", v14.

This series is in order to enable sparse-vmemmap for LoongArch. But
LoongArch cannot use generic helpers directly because MIPS&LoongArch need
to call pgd_init()/pud_init()/pmd_init() when populating page tables. So
we adjust the prototypes of p?d_init() to make generic helpers can call
them, then enable sparse-vmemmap with generic helpers, and to be further,
generalise vmemmap_populate_hugepages() for ARM64, X86 and LoongArch.


This patch (of 4):

We are preparing to add sparse vmemmap support to LoongArch. MIPS and
LoongArch need to call pgd_init()/pud_init()/pmd_init() when populating
page tables, so adjust their prototypes to make generic helpers can call
them.

NIOS2 declares pmd_init() but doesn't use, just remove it to avoid build
errors.
