Build a static linked, small dmsetup tool
======== Source Code ========
use an old version of dmsetup
xxx/centos-vault/5.3/os/SRPMS/device-mapper-1.02.28-2.el5.src.rpm
======== Build Envrioment ========
build for 32bit, static linked with dietlibc
1. install centos 6.10 i386 with CentOS-6.10-i386-bin-DVD1.iso
2. yum install gcc kernel-devel package
3. install dietc libc (just make && make install)
4. export PATH=$PATH:/opt/diet/bin
======== Build Step ========
1. extract device mapper source code
2. CC="diet gcc" ./configure --disable-nls --disable-selinux --disable-shared
3. modify include/configure.h file
--- delete the line with "#define malloc rpl_malloc"
--- add 2 defines as follow:
#ifndef UINT32_MAX
#define UINT32_MAX (4294967295U)
#endif
#ifndef UINT64_C
#define UINT64_C(c) c ## ULL
#endif
4. make
5. strip dmsetup/dmsetup
5. get dmsetup/dmsetup as the binary file

========== About Source Code =============
Ventoy add an UEFI application module in MdeModulePkg, so I only put the module's source code here.
You can download the EDK2 code from https://github.com/tianocore/edk2 and merge the code together.
========== Build =============
Follow the EDK2's build instructions

========== About Source Code =============
Ventoy use grub-2.04, so I only put the added and modified source code here.
You can download grub-2.04 source code from this site:
https://ftp.gnu.org/gnu/grub/
Just merge the code here with the original code of grub-2.04
========== Build =============
