2018-08-30x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parametersBin Meng
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 <bmeng.cn@gmail.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Simon Glass <sjg@chromium.org>

This changes 'struct e820entry' to 'struct e820_entry' to conform with the coding style. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2018-03-30x86: zImage: Pass working device tree data to the kernelIvan Gorinov
On x86 platforms, U-Boot does not pass Device Tree data to the kernel. This prevents the kernel from using FDT loaded by U-Boot. Read the working FDT address from the "fdtaddr" environment variable and add a copy of the FDT data to the kernel setup_data list.

2018-01-30x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parametersAndy Shevchenko
New field acpi_rsdp_addr, which has been introduced in boot protocol v2.14 [1], in boot parameters tells kernel the exact address of RDSP ACPI table. Knowing it increases robustness of the kernel by avoiding in some cases traversal through a part of physical memory. It will slightly reduce boot time by the same reason. [1] See Linux kernel commit 2f74cbf ("x86/boot: Add the ACPI RSDP address to struct setup_header::acpi_rdsp_addr") @ https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f74cbf for the details.

2016-10-11x86: Fix Linux v4.7+ zimage booting (update bootparam.h)Stefan Roese
Booting Linux kernel v4.7+ does not work since Linux kernel commit 974f221c "x86/boot: Move compressed kernel to the end of the decompression buffer". This patch adds the latest version of the setup_header struct, adding "init_size" which is needed since this commit referenced above. With this patch, booting Linux v4.8-rc8 does work again on x86 boards.
