x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parameters

2018-08-30T03:23:15Z

As of today, the proposal of adding "acpi_rsdp_addr" to the kernel boot protocol does not make its way to the kernel mainline. This creates some confusion if we leave it in the U-Boot code base. Remove it for now until we have a clear picture with kernel upstream. Note this eventually does a partial revert to commit 3469bf427454 ("x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters") Signed-off-by: Bin Meng Acked-by: Andy Shevchenko Reviewed-by: Simon Glass

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

Patch queue for efi - 2018-08-21 A few fixes for 2018.09. Most noticable are: - unbreak x86 target (-fdata-section fallout) - fix undefined behavior in a few corner cases - make Jetson TX1 boot again - RTS fixes - implement reset for simple output

x86: Enable -fdata-sections always

2018-08-20T12:20:53Z

We left -fdata-sections disabled for x86_64 before because we encountered random bugs that were at that time inexplicable. Turns out this really was just side effects of missing .bss* statements in the linker scripts. With those fixed, we can enable data sections for all targets. Signed-off-by: Alexander Graf

x86: Include bss subsections in linker script

2018-08-20T12:17:43Z

When we build with -fdata-sections we may end up with bss subsections. Our linker script explicitly lists only a single consecutive bss section though. Adapt the statement to also include subsections. This fixes booting efi-x86_app_defconfig. Signed-off-by: Alexander Graf

x86: efi: payload: Add default TSC frequency in the device tree

2018-08-20T05:52:49Z

It was observed sometimes U-Boot as the EFI payload fails to boot on QEMU. This is because TSC calibration fails with no valid frequency. This adds default TSC frequency in the device tree. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: dts: Remove coreboot_fb.dtsi

2018-08-20T05:52:49Z

There is no need to keep a separate coreboot_fb.dtsi since now we have a generic coreboot payload dts. While we are here, this also remove the out-of-date description in the documentation regarding to coreboot framebuffer driver with U-Boot loaded as a payload from coreboot. As the testing result with QEMU 2.5.0 shows, the driver just works like a charm. Signed-off-by: Bin Meng Reviewed-by: Simon Glass
