Blastproof boot process

Blastproof boot process follow a very rigid sequences of steps that are detailled below:

Printing informations:
- Bootloader version
- Firmware informations
- CPU informations
Reading boot password from EFI console
Verifying integrity of integrated keys (see SBFIE)
Acquiring access to ESP partition
- Acquiring loaded image handle
- Acquiring BlockIO protocol for ESP partition
- Acquiring filesystem protocol (Blastproof doesn't have an integrated FAT32 driver)
- Opening root folder
Performing cryptographic checks with internal keys on his own files (see SBFIE)
Readind, parsing and applying boot configuration
Locating Simple Graphic Protocol (GOP) handle
Identify a suitable graphic output format, based on configuration, or highest resolution available in case of fallback
Loading and rendering bitmap font according to selected graphic output format
Loading, rendering and playing boot animation if configuration allow it
Loading InitFS and SignSyst
- Listing all availables BlockIO protocol
- Locating handles for InitFS and SignSyst
- Allocating memory for them
- Loading them into RAM
- Parsing their headers
- Performing cryptographic checks to validate their headers and contents
Loading the kernel
- Loading Shelter and Keycard binary
- Generating Shelter boot configuration
- Allocating pages for kernel sections
- Creating page table
- Parsing EFI Memory Map and transforming it into a understandable format for Vystem
- Jumping to kernel
