efi: payload: only init usb if necessary

2018-12-10T02:14:42Z

Up until now the call to initialize the USB subsystem was hardcoded for U-Boot running as an EFI payload. This was used to enable the use of a USB keyboard in the U-Boot shell. However not all boards might need this functionality. As initializing the USB subsystem can take a considerable amount of time (several seconds on some boards), we now initialize the USB subsystem only if U-Boot is configured to use USB keyboards.

x86: zimage: Support booting Linux kernel from an EFI payload

2018-08-30T03:23:14Z

At present Linux kernel loaded from U-Boot as an EFI payload does not boot. This fills in kernel's boot params structure with the required critical EFI information like system table address and memory map stuff so that kernel can obtain essential data like runtime services and ACPI table to boot. With this patch, now U-Boot as an EFI payload becomes much more practical: it is another option of kernel bootloader, ie, can be a replacement for grub.

x86: efi: payload: Install E820 map from EFI memory map

2018-08-30T01:56:58Z

This implements payload-specific install_e820_map() to get E820 map from the EFI memory map descriptors. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: efi: payload: Count in conventional memory above 4GB in DRAM bank

2018-06-24T00:56:25Z

At present in dram_init_banksize() it ignores conventional memory above 4GB. This leads to wrong DRAM size is printed during boot. Remove such limitation. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: efi-x86_payload: Enable usb keyboard during boot

2018-06-24T00:56:04Z

For boards that don't route serial port pins out, it's quite common to attach a USB keyboard as the input device, along with a monitor. However USB is not automatically started in the generic efi payload codes. This uses a payload specific last_stage_init() to start the USB bus, so that a USB keyboard can be used on the U-Boot shell.

x86: efi: app: Display correct CPU info during boot

2018-06-17T13:16:04Z

Currently when EFI application boots, it says: CPU: x86_64, vendor , device 0h Fix this by calling x86_cpu_init_f() in arch_cpu_init(). Signed-off-by: Bin Meng Reviewed-by: Simon Glass

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

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
