One result is that microcode updates can only be done before RAM is available and therefore parsing of the device tree is impracticle. Worse, the addess of the microcode update must be stored in ROM since a pointer to its start address and size is passed to the 'FSP' blob. It is not possible to perform any calculations to obtain the address and size. To work around this, ifdtool is enhanced to work out the address and size of the first microcode update it finds in the supplied device tree. It then writes these into the correct place in the ROM. U-Boot can then start up the FSP correctly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Also add a 'type' member since we will shortly add additional types. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

tools/ifdtool: Support writing multiple files (-w) simultaneously 2014-12-14T05:32:04+00:00 Bin Meng bmeng.cn@gmail.com 2014-12-12T13:05:20+00:00 673ed2f8c2e6b5526de929861d7dd42834c572fd Currently ifdtool only supports writing one file (-w) at a time. This looks verbose when generating u-boot.rom for x86 targets. This change allows at most 16 files to be written simultaneously.
