* include: Introduce elf64.h and elf.h
Added elf64.h for 64bit ELF support and moved common definitions
from elf32.h to elf.h. Also introduced Elf_xxx to be used in
common libraries such as binfmt.
* binfmt, include, modlib, module: Add support for ELF64
Elf_xxx must be used instead of Elf32_xxx to support ELF64.
To use ELF64, CONFIG_ELF_64BIT must be enabled.
* binfmt, modlib: Add support for relocate address
* arch: risc-v: Add include/elf.h
* libs: machine: Add risc-v related files.
NOTE: Currently only supports ELF64
* boards: maix-bit: Add elf and posix_spawn configurations
* boards: maix-bit: Add support for module configuration

int "ELF I/O Buffer Size"
|
|
default 32
|
|
---help---
|
|
This is an I/O buffer that is used to access the ELF file. Variable length items
|
|
will need to be read (such as symbol names). This is really just this initial
|
|
size of the buffer; it will be reallocated as necessary to hold large symbol
|
|
names). Default: 32
