x86: Add support for starting from SPL/TPL

2019-05-08T05:02:13Z

When a previous phase of U-Boot has run we need to adjust the init of subsequent states to avoid messing up the CPU state. Add a new version of the start logic for SPL, when it boots from TPL (start_from tpl.c) and a new version for U-Boot when it boots from SPL. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: make the LAPIC / IOAPIC construct switchable with Kconfig

2018-12-10T02:12:29Z

There are still systems running which do not have any LAPIC or even IOAPIC. Responsible MSRs for those do not exist and the systems are crashing on trying to setup LAPIC. This commit makes the APIC stuff able to switch off for those boards which dont' have an LAPIC / IOAPIC. Signed-off-by: Hannes Schmelzer Reviewed-by: Bin Meng

x86: efi: Refactor the directory of EFI app and payload support

2018-06-17T13:16:04Z

At present the EFI application and payload support codes in the x86 directory is distributed in a hybrid way. For example, the Kconfig options for both app and payload are in arch/x86/lib/efi/Kconfig, but the source codes in the same directory get built only for CONFIG_EFI_STUB. This refactors the codes by consolidating all the EFI support codes into arch/x86/cpu/efi, just like other x86 targets. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: efi: payload: Enforce toolchain to generate 64-bit EFI payload stub codes

2018-06-13T01:50:57Z

Attempting to use a toolchain that is preconfigured to generate code for the 32-bit architecture (i386), for example, the i386-linux-gcc toolchain on kernel.org, to compile the 64-bit EFI payload does not build. This updates the makefile fragments to ensure '-m64' is passed to toolchain when building the 64-bit EFI payload stub codes. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

x86: Add Intel Braswell SoC support

2017-09-16T06:57:44Z

This adds initial Intel Braswell SoC support. It uses Intel FSP to initialize the chipset. Similar to its predecessor BayTrail, there are some work to do to enable the legacy UART integrated in the Braswell SoC. Signed-off-by: Bin Meng Reviewed-by: Simon Glass
