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.

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: 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: Use microcode update from device tree for all processors

2018-07-02T01:23:28Z

Built without a ROM image with FSP (u-boot.rom), the U-Boot loader applies the microcode update data block encoded in Device Tree to the bootstrap processor but not passed to the other CPUs when multiprocessing is enabled. If the bootstrap processor successfully performs a microcode update from Device Tree, use the same data block for the other processors.

x86: Change __kernel_size_t conditionals to use compiler provided defines

2018-06-24T00:56:04Z

Since commit bb0bb91cf0aa ("efi_stub: Use efi_uintn_t"), EFI x86 64-bit payload does not work anymore. The call to GetMemoryMap() in efi_stub.c fails with return code EFI_INVALID_PARAMETER. Since the payload itself is still 32-bit U-Boot, efi_uintn_t gets wrongly interpreted as int, but it should actually be long in a 64-bit EFI environment. This changes the x86 __kernel_size_t conditionals to use compiler provided defines instead. That way we always adhere to the build environment we're in and the definitions adjust automatically.

x86: irq: Support discrete PIRQ routing registers via device tree

2018-06-13T01:50:57Z

Currently both pirq_reg_to_linkno() and pirq_linkno_to_reg() assume consecutive PIRQ routing control registers. But this is not always the case on some platforms. Introduce a new device tree property intel,pirq-regmap to describe how the PIRQ routing register offset is mapped to the link number and adjust the irq router driver to utilize the mapping.
