+
+### Preperations
+In order to build coreboot, it's neccessary to extract some files from the vendor firmware. Make sure that you have a fully working dump.
+```bash
+[upsquared]$ ls
+firmware_vendor.rom
+```
+
+```bash
+[upsquared]$ mkdir extracted && cd extracted
+[extracted]$ ifdtool -x ../firmware_vendor.rom

+flashregion_5_reserved.bin
+```
+
+### Clean up
+```bash
+[coreboot]$ make distclean
+```
+
+### Configuring
+```bash
+[coreboot]$ touch .config
+[coreboot]$ ./util/scripts/config --enable VENDOR_UP
+[coreboot]$ ./util/scripts/config --enable BOARD_UP_SQUARED
+[coreboot]$ ./util/scripts/config --enable NEED_IFWI

+
+### Building
+```bash

+# Apollolake
+## SPI flash layout
+
+![][apl_flash_layout]
+
+With Apollolake Intel invented another flash layout for x86 firmware called IFWI (Intel FirmWare Image).
+
+Usually on x86 platforms the bootblock is stored at the end of the bios region
+and the Intel ME / TXE has its own IFD region. On Apollolake both have been
+moved into the IFWI region, which is a subregion of "BIOS", since it allows to
+store multiple firmware components.
+
+The IFWI region can be manipulated by `ifwitool`.
