BOOTBOOT lefordítható [coreboot](https://coreboot.org) payloadként is, lásd *x86_64-cb* és *aarch64-cb*, de mivel ezek szorosan
kapcsolódnak a libpayload-hoz, nincs belőlük előre fordított bináris.

BOOTBOOT Coreboot ARM64 Implementáció
=====================================
Általános leírásért lásd a [BOOTBOOT Protokoll](https://gitlab.com/bztsrc/bootboot)t.
Ez [coreboot](https://coreboot.org) payloadként implementálja a BOOTBOOT Protokollt. Jelenleg __FEJLESZTÉS ALATT__.
A coreboot fordítási környezetben fordítandó.
Fordítás
--------
### 1. lépés - Függőségek telepítése
Először is, telepíteni kell a [coreboot függőségei](https://doc.coreboot.org/tutorial/part1.html)t: bison, build-essentials, curl,
flex, git, gnat, libncurses5-dev, m4, zlib. A legfrissebb listáért nézd meg a linkelt dokumentumot.
### 2. lépés - A coreboot beszerzése
Töltsd le a coreboot-ot minden almoduljával együtt
```sh
$ git clone https://review.coreboot.org/coreboot
$ cd coreboot
$ git submodule update --init
```
Nagyon fontos, hogy inicializáld az almodulokat, máskülönben nem fog lefordulni a coreboot.
### 3. lépés - Fordítókörnyezet (toolchain) létrehozása
Ez el fog tartani egy jódarabig. A *$(nproc)* helyett add meg, hogy hány CPU core-od van.
```sh
$ make crossgcc-aarch64 CPUS=$(nproc)
```
### 4. lépés - A coreboot pecselése és konfigurálása
Másold át és írd felül a [../coreboot könyvtár](https://gitlab.com/bztsrc/bootboot/tree/master/coreboot) fájlait a
coreboot projekted munkakönyvtárába. Ez frissíteni fogja a coreboot konfigurációs rendszerét.
Ezután be kell konfigurálnod a coreboot-ot, hogy milyen alaplapot (vagy qemu-t) kezeljen, és hogy BOOTBOOT-al induljon.
```sh
$ make menuconfig
válaszd a 'Mainboard' menüt
alatta a 'Mainboard vendor' legyen '(Emulation)'
alatta a 'Mainboard model' legyen 'QEMU AArch64'
válaszd az 'Exit'-t
válaszd a 'Payload' menüt
válaszd az 'Add a Payload' opciót
válaszd ki a 'BOOTBOOT'-ot
válaszd az 'Exit'-t
válaszd az 'Exit'-t
válaszd a 'Yes'-t
```
### 5. lépés - A coreboot fordítása
```sh
$ make
```
### 6. lépés - A frissen fordított ROM tesztelése QEMU-n
Bővebb információért lásd a [coreboot dokumentáció](https://doc.coreboot.org/mainboard/emulation/qemu-aarch64.html)t.
```sh
$ qemu-system-aarch64 -bios $(COREBOOT)/build/coreboot.rom -M virt,secure=on,virtualization=on -cpu cortex-a53 -m 1024M \
-drive file=$(BOOTBOOT)/images/disk-rpi.img,format=raw -serial stdio
```
Gép állapot
-----------
A kód felügyeleti módban, EL1-en fut minden processzoron.
Telepítés
---------
Miután lefordítottad a coreboot ROM-ot BOOTBOOT payloaddal, [flashelheted a build/coreboot.rom](https://doc.coreboot.org/flash_tutorial/index.html)
fájlt az alaplapodra.
Limitációk
----------
- Csak a SHA-XOR-CBC titkosítást ismeri, nincs AES

BOOTBOOT Coreboot ARM64 Implementation
======================================
See [BOOTBOOT Protocol](https://gitlab.com/bztsrc/bootboot) for common details.
Implements the BOOTBOOT Protocol as a [coreboot](https://coreboot.org) payload. Currently __EXPERIMENTAL__.
Must be compiled using the coreboot build environment.
Compilation
-----------
### Step 1 - Install dependencies
First, install the [coreboot dependencies](https://doc.coreboot.org/tutorial/part1.html): bison, build-essentials, curl,
flex, git, gnat, libncurses5-dev, m4, zlib. Please refer to the linked doc for up-to-date list of dependencies.
### Step 2 - Get coreboot
Download coreboot and its submodules
```sh
$ git clone https://review.coreboot.org/coreboot
$ cd coreboot
$ git submodule update --init
```
It is very important to initialize submodules, otherwise you won't be able to compile coreboot.
### Step 3 - Create toolchain
This step could take a while. Replace *$(nproc)* with the number of CPU cores you have.
```sh
$ make crossgcc-aarch64 CPUS=$(nproc)
```
### Step 4 - Patch coreboot and configure
Copy and overwrite files from [../coreboot directory](https://gitlab.com/bztsrc/bootboot/tree/master/coreboot) to the
coreboot working directory. This will update the coreboot configuration system.
Now configure coreboot for your motherboard (or qemu) and BOOTBOOT.
```sh
$ make menuconfig
select 'Mainboard' menu
Beside 'Mainboard vendor' should be '(Emulation)'
Beside 'Mainboard model' should be 'QEMU AArch64'
select 'Exit'
select 'Payload' menu
select 'Add a Payload'
choose 'BOOTBOOT'
select 'Exit'
select 'Exit'
select 'Yes'
```
### Step 5 - Build coreboot
```sh
$ make
```
### Step 6 - Test the newly compiled ROM in QEMU
For more information, read [coreboot docs](https://doc.coreboot.org/mainboard/emulation/qemu-aarch64.html).
```sh
$ qemu-system-aarch64 -bios $(COREBOOT)/build/coreboot.rom -M virt,secure=on,virtualization=on -cpu cortex-a53 -m 1024M \
-drive file=$(BOOTBOOT)/images/disk-rpi.img,format=raw -serial stdio
```
Machine state
-------------
Code is running in supervisor mode, at EL1 on all cores.
Installation
------------
Once you have compiled a coreboot ROM with the BOOTBOOT payload, you can
[flash the build/coreboot.rom](https://doc.coreboot.org/flash_tutorial/index.html) file to your mainboard.
Limitations
-----------
- Only supports SHA-XOR-CBC, no AES

BOOTBOOT Coreboot x86_64 Implementáció
======================================
Általános leírásért lásd a [BOOTBOOT Protokoll](https://gitlab.com/bztsrc/bootboot)t.
Ez [coreboot](https://coreboot.org) payloadként implementálja a BOOTBOOT Protokollt. Jelenleg __FEJLESZTÉS ALATT__.
A coreboot fordítási környezetben fordítandó.
Fordítás
--------
### 1. lépés - Függőségek telepítése
Először is, telepíteni kell a [coreboot függőségei](https://doc.coreboot.org/tutorial/part1.html)t: bison, build-essentials, curl,
flex, git, gnat, libncurses5-dev, m4, zlib. A legfrissebb listáért nézd meg a linkelt dokumentumot.
### 2. lépés - A coreboot beszerzése
Töltsd le a coreboot-ot minden almoduljával együtt
```sh
$ git clone https://review.coreboot.org/coreboot
$ cd coreboot
$ git submodule update --init
```
Nagyon fontos, hogy inicializáld az almodulokat, máskülönben nem fog lefordulni a coreboot.
### 3. lépés - Fordítókörnyezet (toolchain) létrehozása
Ez el fog tartani egy jódarabig. A *$(nproc)* helyett add meg, hogy hány CPU core-od van.
```sh
$ make crossgcc-i386 CPUS=$(nproc)
```
### 4. lépés - A coreboot pecselése és konfigurálása
Másold át és írd felül a [../coreboot könyvtár](https://gitlab.com/bztsrc/bootboot/tree/master/coreboot) fájlait a
coreboot projekted munkakönyvtárába. Ez frissíteni fogja a coreboot konfigurációs rendszerét.
Ezután be kell konfigurálnod a coreboot-ot, hogy milyen alaplapot (vagy qemu-t) kezeljen, és hogy BOOTBOOT-al induljon.
```sh
$ make menuconfig
válaszd a 'Mainboard' menüt
alatta a 'Mainboard vendor' legyen '(Emulation)'
alatta a 'Mainboard model' legyen 'QEMU x86 i440fx/piix4'
válaszd az 'Exit'-t
válaszd a 'Payload' menüt
válaszd az 'Add a Payload' opciót
válaszd ki a 'BOOTBOOT'-ot
válaszd az 'Exit'-t
válaszd az 'Exit'-t
válaszd a 'Yes'-t
```
### 5. lépés - A coreboot fordítása
```sh
$ make
```
### 6. lépés - A frissen fordított ROM tesztelése QEMU-n
Bővebb információért lásd a [coreboot dokumentáció](https://doc.coreboot.org/mainboard/emulation/qemu-i440fx.html)t.
```sh
$ qemu-system-x86_64 -bios $(COREBOOT)/build/coreboot.rom -drive file=$(BOOTBOOT)/images/disk-x86.img,format=raw -serial stdio
```
Gép állapot
-----------
IRQ-k letiltva, GDT nincs meghatározva, de érvényes, IDT nincs beállítva. SSE, SMP engedélyezve. Kód felügyeleti módban, 0-ás gyűrűn
fut minden processzormagon.
Telepítés
---------
Miután lefordítottad a coreboot ROM-ot BOOTBOOT payloaddal, [flashelheted a build/coreboot.rom](https://doc.coreboot.org/flash_tutorial/index.html)
fájlt az alaplapodra.
Limitációk
----------
- Mivel védett módban indul, csak az első 4G-nyi RAM-ot képezi le.
- A CMOS nvram nem tárol időzónát, ezért mindig GMT+0 kerül a bootboot.timezone-ba.
- Csak a SHA-XOR-CBC titkosítást ismeri, nincs AES

BOOTBOOT Coreboot x86_64 Implementation
=======================================
See [BOOTBOOT Protocol](https://gitlab.com/bztsrc/bootboot) for common details.
Implements the BOOTBOOT Protocol as a [coreboot](https://coreboot.org) payload. Currently __EXPERIMENTAL__.
Must be compiled using the coreboot build environment.
Compilation
-----------
### Step 1 - Install dependencies
First, install the [coreboot dependencies](https://doc.coreboot.org/tutorial/part1.html): bison, build-essentials, curl,
flex, git, gnat, libncurses5-dev, m4, zlib. Please refer to the linked doc for up-to-date list of dependencies.
### Step 2 - Get coreboot
Download coreboot and its submodules
```sh
$ git clone https://review.coreboot.org/coreboot
$ cd coreboot
$ git submodule update --init
```
It is very important to initialize submodules, otherwise you won't be able to compile coreboot.
### Step 3 - Create toolchain
This step could take a while. Replace *$(nproc)* with the number of CPU cores you have.
```sh
$ make crossgcc-i386 CPUS=$(nproc)
```
### Step 4 - Patch coreboot and configure
Copy and overwrite files from [../coreboot directory](https://gitlab.com/bztsrc/bootboot/tree/master/coreboot) to the
coreboot working directory. This will update the coreboot configuration system.
Now configure coreboot for your motherboard (or qemu) and BOOTBOOT.
```sh
$ make menuconfig
select 'Mainboard' menu
Beside 'Mainboard vendor' should be '(Emulation)'
Beside 'Mainboard model' should be 'QEMU x86 i440fx/piix4'
select 'Exit'
select 'Payload' menu
select 'Add a Payload'
choose 'BOOTBOOT'
select 'Exit'
select 'Exit'
select 'Yes'
```
### Step 5 - Build coreboot
```sh
$ make
```
### Step 6 - Test the newly compiled ROM in QEMU
For more information, read [coreboot docs](https://doc.coreboot.org/mainboard/emulation/qemu-i440fx.html).
```sh
$ qemu-system-x86_64 -bios $(COREBOOT)/build/coreboot.rom -drive file=$(BOOTBOOT)/images/disk-x86.img,format=raw -serial stdio
```
Machine state
-------------
IRQs masked. GDT unspecified, but valid, IDT unset. SSE, SMP enabled. Code is running in supervisor mode in ring 0 on all cores.
Installation
------------
Once you have compiled a coreboot ROM with the BOOTBOOT payload, you can
[flash the build/coreboot.rom](https://doc.coreboot.org/flash_tutorial/index.html) file to your mainboard.
Limitations
-----------
- As it boots in protected mode, it only maps the first 4G of RAM.
- The CMOS nvram does not store timezone, so always GMT+0 returned in bootboot.timezone.
- Only supports SHA-XOR-CBC, no AES
