* binman: Drop microcode features from ifdtoolSimon Glass2016-12-20-249/+5
| | | | | | | | | Now that binman supports creating images with microcode, drop the code from ifdtool. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
* x86: ifdtool: Support checking region overlap before U-BootBin Meng2015-09-09-20/+46
| | | | | | | | | | | We have the capability to check regions written after U-Boot that do not overlap. Since regions can also be written before U-Boot, add such check for these too.

* x86: ifdtool: Drop microcode from the device tree when collatingSimon Glass2015-08-26-2/+53
| | | | | | | | | | | | | | When ifdtool collates the microcode into one place it effectively creates a copy of the 'data' properties in the device tree microcode nodes. This is wasteful since we now have two copies of the microcode in the ROM. To avoid this, remove the microcode data from the device tree and shrink it down. This means that there is only one copy and the overall ROM space used by the microcode does not increase.

* x86: ifdtool: Support collating microcode into one placeSimon Glass2015-08-26-10/+55
| | | | | | | | | | | | | | | | | | | | | The Intel Firmware Support Package (FSP) requires that microcode be provided very early before the device tree can be scanned. We already support adding a pointer to the microcode data in a place where early init code can access. However this just points into the device tree and can only point to a single lot of microcode. For boards which may have different CPU types we must support multiple microcodes and pass all of them to the FSP in one place. Enhance ifdtool to scan all the microcode, place it together in the ROM and update the microcode pointer to point there. This allows us to pass multiple microcode blocks to the FSP using its existing API. Enable the flag in the Makefile so that this feature is used by default for all boards.

* x86: ifdtool: Split microcode linking into its own functionSimon Glass2015-08-26-27/+78
| | | | | | | | | | | The code to set up the microcode pointer in the ROM shares almost nothing with the write_uboot() function. Move it into its own function so it will be easier to extend.

* x86: ifdtool: Check that U-Boot does not overlap other regionsSimon Glass2015-08-26-11/+22
| | | | | | | | | | Since U-Boot and its device tree can grow we should check that it does not overlap the regions above it. Track the ROM offset that U-Boot reaches and check that other regions (written after U-Boot) do not interfere.

* tools: ifdtool: Write correct offset on 32-bit machineBin Meng2015-07-14-1/+1
| | | | | | | | | | | On 32-bit machine strtol() returns LONG_MAX which is 0x7fffffff, which is wrong for u-boot.rom components like u-boot-x86-16bit.bin. Change to use strtoll() so that it works on both 32-bit and 64-bit machines.

* x86: ifdtool: Add support for early microcode accessSimon Glass2014-12-18-8/+102
| | | | | | | | | | | | | | | | | | | Some Intel CPUs use an 'FSP' binary blob which provides an inflexible means of starting up the CPU. 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>

* x86: Add ifdtool for working with Intel Flash Descriptor ROM imagesSimon Glass2014-11-21-0/+1039
Newer Intel chips require a Management Engine which requires a particular format for the SPI flash that contains the boot loader. Add a tool that supports creating and modifying these ROM images. This tool is from Chrome OS but has been cleaned up to use U-Boot style and to add comments. A few features have been added also. Signed-off-by: Simon Glass <sjg@chromium.org>
