| | | | | | | | | Add support for building U-Boot as an EFI application with a .efi suffix. This can be loaded by EFI provided that EFI has the same bit width (32- or 64-bit) as U-Boot. This unfortunate limitation is imposed by EFI. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | | | | When U-Boot runs as an EFI application is does not have a definition of CONFIG_SYS_TEXT_BASE. U-Boot is a relocatable application and the relocation is done by EFI. U-Boot can be loaded at any address. Ensure that this CONFIG option is not set in this case.

* Add a way to skip relocationSimon Glass2015-08-05-0/+10
| | | | | | | | | | | When running U-Boot as an EFI application we cannot relocate since we do not have relocation information. U-Boot has already been relocated to a suitable address.

* x86: Update README to explain booting Ubuntu on MinnowmaxSimon Glass2015-08-05-0/+278
| | | | | | | | | | | | | | | | The steps required to boot a Linux distribution from U-Boot on x86 are not very complicated, but it is a good idea to have these written down in an accessible place. Document how to examine the boot media from U-Boot, how to load a kernel, load a ramdisk, set the kernel boot arguments and start the kernel. With these instructions Ubuntu boots mostly normally on Minnowmax. Note that the TSC timer does not operate correctly and gives warnings in the boot log. I expect that ACPI support will solve this.

| | | | | | | | | | At present the PCI output displays 'Mem' when it allocates memory for a PCI device, whether it is prefetchable or not.

* efi: Display the correct initcall pre-relocation valuesSimon Glass2015-08-05-0/+4
| | | | | | | | | | | | With EFI the start address of U-Boot is specified differently. We could consider just setting GD_FLG_RELOC and then setting up reloc_off. But that flag has other implementations and we are not able to use U-Boot relocation which this flag implies. Instead, just add a special case for EFI.

* efi: Add start-up library codeSimon Glass2015-08-05-64/+887
| | | | | | | | | | | When running as an EFI application, U-Boot must request memory from EFI, and provide access to the boot services U-Boot needs. Add library code to perform these tasks. This includes efi_main() which is the entry point from EFI. U-Boot is built as a shared library. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Allow use of global_data with EFISimon Glass2015-08-05-0/+7
| | | | | | | | | | | | | | | On x86 the global_data pointer is provided through a somewhat-bizarre and x86-specific mechanism: the F segment register is set to a pointer to the start of global_data, so that accesses can use this build-in register. When running as an EFI application we don't want to mess with the Global Descriptor Table (GDT) and there is little advantage (in terms of code size) to doing so. Allow global_data to be a simple variable in this case. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
