|

This target is used for running U-Boot on top of Slim Bootloader
|
||||
boot firmware as a payload. Slim Bootloader does memory initialization
|
||||
and silicon initialization, and it passes necessary information in
|
||||
HOB (Hand Off Block) to a payload. The payload consumes HOB data
|
||||
which is generated by Slim Bootloader for its driver initialization.
|
||||
Slim Bootloader consumes FSP and its HOB, but FSP HOB is cleared
|
||||
Before launching a payload. Instead, Slim Bootloader generates its
|
||||
HOB data such as memory info, serial port info and so on.
|
||||
Refer to doc/board/intel/slimbootloader.rst for the details.

Slim Bootloader
|
||||
===============
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
This target is to enable U-Boot_ as a payload of `Slim Bootloader`_ (a.k.a SBL)
|
||||
boot firmware which currently supports QEMU, Apollolake, Whiskeylake,
|
||||
Coffeelake-R platforms.
|
||||
|
||||
The `Slim Bootloader`_ is designed with multi-stages (Stage1A/B, Stage2, Payload)
|
||||
architecture to cover from reset vector to OS booting and it consumes
|
||||
`Intel FSP`_ for silicon initialization.
|
||||
|
||||
* Stage1A: Reset vector, CAR init with FSP-T
|
||||
* Stage1B: Memory init with FSP-M, CAR teardown, Continue execution in memory
|
||||
* Stage2 : Rest of Silicon init with FSP-S, Create HOB, Hand-off to Payload
|
||||
* Payload: Payload init with HOB, Load OS from media, Booting OS
|
||||
|
||||
The Slim Bootloader stages (Stage1A/B, Stage2) focus on chipset, hardware and
|
||||
platform specific initialization, and it provides useful information to a
|
||||
payload in a HOB (Hand-Off Block) which has serial port, memory map, performance
|
||||
data info and so on. This is Slim Bootloader architectural design to make a
|
||||
payload light-weight, platform independent and more generic across different
|
||||
boot solutions or payloads, and to minimize hardware re-initialization in a
|
||||
payload.
|
||||
|
||||
Build Instruction for U-Boot as a Slim Bootloader payload
|
||||
---------------------------------------------------------
|
||||
|
||||
Build U-Boot and obtain u-boot-dtb.bin::
|
||||
|
||||
$ make distclean
|
||||
$ make slimbootloader_defconfig
|
||||
$ make all
|
||||
|
||||
Prepare Slim Bootloader
|
||||
-----------------------
|
||||
|
||||
1. Setup Build Environment for Slim Bootloader.
|
||||
|
||||
Refer to `Getting Started`_ page in `Slim Bootloader`_ document site.
|
||||
|
||||
2. Get source code. Let's simply clone the repo::
|
||||
|
||||
$ git clone https://github.com/slimbootloader/slimbootloader.git
|
||||
|
||||
3. Copy u-boot-dtb.bin to Slim Bootloader.
|
||||
Slim Bootloader looks for a payload from the specific location.
|
||||
Copy the build u-boot-dtb.bin to the expected location::
|
||||
|
||||
$ mkdir -p <Slim Bootloader Dir>/PayloadPkg/PayloadBins/
|
||||
$ cp <U-Boot Dir>/u-boot-dtb.bin <Slim Bootloader Dir>/PayloadPkg/PayloadBins/u-boot-dtb.bin
|
||||
|
||||
Build Instruction for Slim Bootloader for QEMU target
|
||||
-----------------------------------------------------
|
||||
|
||||
Slim Bootloader supports multiple payloads, and a board of Slim Bootloader
|
||||
detects its target payload by PayloadId in board configuration.
|
||||
The PayloadId can be any 4 Bytes value.
|
||||
|
||||
1. Update PayloadId. Let's use 'U-BT' as an example::
|
||||
|
||||
$ vi Platform/QemuBoardPkg/CfgData/CfgDataExt_Brd1.dlt
|
||||
-GEN_CFG_DATA.PayloadId | 'AUTO'
|
||||
+GEN_CFG_DATA.PayloadId | 'U-BT'
|
||||
|
||||
2. Update payload text base. PAYLOAD_EXE_BASE must be the same as U-Boot
|
||||
CONFIG_SYS_TEXT_BASE in board/intel/slimbootloader/Kconfig.
|
||||
PAYLOAD_LOAD_HIGH must be 0::
|
||||
|
||||
$ vi Platform/QemuBoardPkg/BoardConfig.py
|
||||
+ self.PAYLOAD_LOAD_HIGH = 0
|
||||
+ self.PAYLOAD_EXE_BASE = 0x00100000
|
||||
|
||||
3. Build QEMU target. Make sure u-boot-dtb.bin and U-BT PayloadId
|
||||
in build command. The output is Outputs/qemu/SlimBootloader.bin::
|
||||
|
||||
$ python BuildLoader.py build qemu -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
|
||||
|
||||
4. Launch Slim Bootloader on QEMU.
|
||||
You should reach at U-Boot serial console::
|
||||
|
||||
$ qemu-system-x86_64 -machine q35 -nographic -serial mon:stdio -pflash Outputs/qemu/SlimBootloader.bin
|
||||
|
||||
Build Instruction for Slim Bootloader for LeafHill (APL) target
|
||||
--------------------------------------------------------------
|
||||
|
||||
LeafHill is using PCI UART2 device as a serial port.
|
||||
For MEM32 serial port, CONFIG_SYS_NS16550_MEM32 needs to be enabled in U-Boot.
|
||||
|
||||
1. Enable CONFIG_SYS_NS16550_MEM32 in U-Boot::
|
||||
|
||||
$ vi include/configs/slimbootloader.h
|
||||
+#define CONFIG_SYS_NS16550_MEM32
|
||||
#ifdef CONFIG_SYS_NS16550_MEM3
|
||||
|
||||
2. Build U-Boot::
|
||||
|
||||
$ make disclean
|
||||
$ make slimbootloader_defconfig
|
||||
$ make all
|
||||
|
||||
3. Copy u-boot-dtb.bin to Slim Bootloader.
|
||||
Slim Bootloader looks for a payload from the specific location.
|
||||
Copy the build u-boot-dtb.bin to the expected location::
|
||||
|
||||
$ mkdir -p <Slim Bootloader Dir>/PayloadPkg/PayloadBins/
|
||||
$ cp <U-Boot Dir>/u-boot-dtb.bin <Slim Bootloader Dir>/PayloadPkg/PayloadBins/u-boot-dtb.bin
|
||||
|
||||
4. Update PayloadId. Let's use 'U-BT' as an example::
|
||||
|
||||
$ vi Platform/ApollolakeBoardPkg/CfgData/CfgData_Int_LeafHill.dlt
|
||||
-GEN_CFG_DATA.PayloadId | 'AUTO
|
||||
+GEN_CFG_DATA.PayloadId | 'U-BT'
|
||||
|
||||
5. Update payload text base.
|
||||
|
||||
* PAYLOAD_EXE_BASE must be the same as U-Boot CONFIG_SYS_TEXT_BASE
|
||||
in board/intel/slimbootloader/Kconfig.
|
||||
* PAYLOAD_LOAD_HIGH must be 0::
|
||||
|
||||
$ vi Platform/ApollolakeBoardPkg/BoardConfig.py
|
||||
+ self.PAYLOAD_LOAD_HIGH = 0
|
||||
+ self.PAYLOAD_EXE_BASE = 0x00100000
|
||||
|
||||
6. Build APL target. Make sure u-boot-dtb.bin and U-BT PayloadId
|
||||
in build command. The output is Outputs/apl/Stitch_Components.zip::
|
||||
|
||||
$ python BuildLoader.py build apl -p "OsLoader.efi:LLDR:Lz4;u-boot-dtb.bin:U-BT:Lzma"
|
||||
|
||||
7. Stitch IFWI.
|
||||
|
||||
Refer to Apollolake_ page in Slim Bootloader document site::
|
||||
|
||||
$ python Platform/ApollolakeBoardPkg/Script/StitchLoader.py -i <Existing IFWI> -s Outputs/apl/Stitch_Components.zip -o <Output IFWI>
|
||||
|
||||
8. Flash IFWI.
|
||||
|
||||
Use DediProg to flash IFWI. You should reach at U-Boot serial console.
|
||||
|
||||
|
||||
Build Instruction to use ELF U-Boot
|
||||
-----------------------------------
|
||||
|
||||
1. Enable CONFIG_OF_EMBED::
|
||||
|
||||
$ vi configs/slimbootloader_defconfig
|
||||
+CONFIG_OF_EMBED=y
|
||||
|
||||
2. Build U-Boot::
|
||||
|
||||
$ make disclean
|
||||
$ make slimbootloader_defconfig
|
||||
$ make all
|
||||
$ strip u-boot (removing symbol for reduced size)
|
||||
|
||||
3. Do same steps as above
|
||||
|
||||
* Copy u-boot (ELF) to PayloadBins directory
|
||||
* Update PayloadId 'U-BT' as above.
|
||||
* No need to set PAYLOAD_LOAD_HIGH and PAYLOAD_EXE_BASE.
|
||||
* Build Slim Bootloader. Use u-boot instead of u-boot-dtb.bin::
|
||||
|
||||
$ python BuildLoader.py build <qemu or apl> -p "OsLoader.efi:LLDR:Lz4;u-boot:U-BT:Lzma"
