2019-12-02common: Move board_get_usable_ram_top() out of common.hSimon Glass
Move this function into init.h which seems to be designed for this sort of thing. Also update the header to declare struct global_data so that it can be included without global_data.h being needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

This function belongs in cpu_func.h so move it over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2018-12-10efi: payload: only init usb if necessaryBin Meng
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.

2018-08-30x86: zimage: Support booting Linux kernel from an EFI payloadBin Meng
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.

2018-08-30x86: efi: payload: Install E820 map from EFI memory mapBin Meng
This implements payload-specific install_e820_map() to get E820 map from the EFI memory map descriptors. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-06-24x86: efi: payload: Count in conventional memory above 4GB in DRAM bankBin Meng
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 <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-06-24x86: efi-x86_payload: Enable usb keyboard during bootBin Meng
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.

This adds arch_cpu_init() to the payload codes, in preparation for supporting a generic efi payload. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-06-17x86: efi: Refactor the directory of EFI app and payload supportBin Meng
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.
