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: 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

elf: Move x86 reloc defines to common elf.h

2018-07-25T12:57:43Z

We need to know about x86 relocation definitions even in cases where we don't officially build against the x86 target, such as with sandbox. So let's move the x86 definitions into the common elf header, where all other architectures already have them. Signed-off-by: Alexander Graf

x86: acpi: Don't touch ACPI hardware in write_acpi_tables()

2018-07-20T01:33:22Z

write_acpi_tables() currently touches ACPI hardware to switch to ACPI mode at the end. Move such operation out of this function, so that it only does what the function name tells us. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Andy Shevchenko

x86: acpi: Move APIs unrelated to ACPI tables generation to a separate library

2018-07-20T01:33:22Z

acpi_find_fadt(), acpi_find_wakeup_vector() and enter_acpi_mode() are something unrelated to ACPI tables generation. Move these to a separate library. This also fixes several style issues reported by checkpatch in the original codes. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Andy Shevchenko

x86: fsp: Eliminate the reset_cpu() call

2018-07-20T01:33:22Z

In preparation for the reset driver conversion, eliminate the reset_cpu() call in the FSP init path as it's too early for the reset driver to work. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: efi_loader: Build EFI memory map per E820 table

On x86 traditional E820 table is used to pass the memory information to kernel. With EFI loader we can build the EFI memory map from it. Signed-off-by: Bin Meng Reviewed-by: Simon Glass
