[PATCH v5 00/17] Add boot LoongArch elf kernel with FDT |

Hi, All
We already support boot efi kernel with bios, but not support boot elf kernel.
This series adds boot elf kernel with FDT.
'LoongArch supports ACPI and FDT. The information that needs to be passed
to the kernel includes the memmap, the initrd, the command line, optionally
the ACPI/FDT tables, and so on' see [1].
Patch 2-8 : Create efi system table, and three efi configuration table
boot_memmap, initd, FDT.
Patch 9-17 : Fixes FDT problems.
Test:
- Start kernel
See [2] start_kernel.sh
- Start qcow2
See [2] start_qcow2.sh
V5:
- Rebase;
V4:
- patch 3 change slave_boot_code[] to const, and 'static void *p ' to
'void *p';
- patch 4 fixes build error;
- patch 10-13, add project and commit link.
V3:
- Load initrd at kernel_high + 4 * kernel_size;
- Load 'boot_rom' at [0 - 1M], the 'boot_rom' includes
slave_boot_code, cmdline_buf and systab_tables;
- R-b and rebase.
V2:
- FDT pcie node adds cells 'msi-map';
