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.
+Prepare U-Boot and Slim Bootloader as described at the beginning of this page.
+Also, the PayloadId needs to be set for APL board.
-1. Enable CONFIG_SYS_NS16550_MEM32 in U-Boot::
-
- $ vi include/configs/slimbootloader.h
- +#define CONFIG_SYS_NS16550_MEM32

-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
