Michael Brown	cfd93465ec	[fdt] Add the concept of an FDT image ... Define the concept of an "FDT" image, representing a Flattened Device Tree blob that has been downloaded in order to be provided to a kernel or other executable image. FDT images are represented using an image tag (as with other special-purpose images such as the UEFI shim), and are similarly marked as hidden so that they will not be included in a generated magic initrd or show up in a virtual filesystem directory listing.

Michael Brown	e520a51df1	[fdt] Add ability to parse a MAC address from a flattened device tree ... The Raspberry Pi NIC has no EEPROM to hold the MAC address. The platform firmware (e.g. UEFI or U-Boot) will typically obtain the MAC address from the VideoCore firmware and add it to the device tree, which is then made available to subsequent programs such as iPXE or the Linux kernel. Add the ability to parse a flattened device tree and to extract the MAC address. Signed-off-by: Michael Brown <mcb30@ipxe.org>	2019-07-19 17:35:39 +01:00
