efi_loader: PSCI reset and shutdown

2018-12-02T20:59:37+00:00

When an operating system started via bootefi tries to reset or power off
this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system
the actual reset relies on PSCI. Depending on whether the PSCI firmware
resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC
or an SMC command has to be issued.

The current implementation always uses SMC. This results in crashes on
systems where the PSCI firmware is implemented in the hypervisor, e.g.
qemu-arm64_defconfig.

The logic to decide which call is needed based on the device tree is
already implemented in the PSCI firmware driver. During the EFI runtime
the device driver model is not available. But we can minimize code
duplication by merging the EFI runtime reset and poweroff code with
the PSCI firmware driver.

As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff
and reset_misc routines let's move them into the same code module.

linux/sizes.h: sync from kernel

2018-11-20T12:08:15+00:00

The kernel added SZ_4G macro in commit f2b9ba871b (arm64/kernel: kaslr:
reduce module randomization range to 4 GB).

Include linux/const.h for the _AC macro.

Drop a local SZ_4G definition in tegra code.

linux/const.h: import from kernel

2018-11-20T12:08:15+00:00

Combine the uapi/linux/const.h header into the kernel linux/const.h. The
next commit will use the _AC macro this header instead of the common.h
definition.

Based on Linux kernel version 4.19.

linux/if_ether.h: Add VLAN related macros

2018-10-10T17:28:53+00:00

There are VLAN related macros defined in include/linux/if_vlan.h
in Linux kernel, as well as some kernel useful structures and inline
functions. Instead of a complete import from kernel, let's add these
VLAN macros to U-Boot's include/linux/if_ether.h.

linux/if_ether.h: Initial import from Linux kernel v4.17

2018-10-10T17:28:51+00:00

This imports include/uapi/linux/if_ether.h from Linux kernel v4.17.
It can be very helpful When porting Linux ethernet driver to U-Boot.

Note it is not exactly the same as the kernel one, as checkpatch
issues are fixed.
