574a7c6c47 Call the PSCI reset from cpu_reset on arm64. When rebooting from DDB the 
kernel calls this directly so the event handler is not called, meaning
the computer fails to reboot.

745c4aa5e8 Make BRCM2837 port conform FreeBSD/ARM64 guidelines 
- Rename SOC_BCM2837 to SOC_BRCM_BCM2837, put it to opt_soc.h
- do not use files.XXX files, just move required sources to
    conf/files.arm64 and make them depend on soc_brcm_bcm2837

563193fd0c Add initial Raspberry Pi 3 support 
RPI3 kernel config builds kernel compatible with latest upstream device
tree and firmware: https://github.com/raspberrypi/firmware/tree/master/boot
As of today it's 597c662a613df1144a6bc43e5f4505d83bd748ca

Default console is PL01x, so pi3-disable-bt dt overlay should be configured
in config.txt and stock U-Boot should be patched to use proper serial port.

Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to
upstream device tree incompatibility.

eefa8817b0 Add SOC_ALLWINNER_A64 option for Allwinner A64 (sun50i) SoCs. 2016-07-11 20:05:03 +00:00

72b3f638b7 Add support for intrng to arm64. As the GICv3 drivers will need to be 
updated, and until further testing can be done, this is disabled for now.

It is expected arm64 will switch to this interface, and the old interface
will be removed before 11.0 is released.

bbbde6d844 Add the SOC_HISI_HI6220 option. This will be used to enable drivers for 
the HiSilicon hi6220 SoC used in the HiKey 96boards board.

75e0dfe336 Add an option to select which SoCs we are building for. It is intended to 
be used with any SoC specific drivers, for example a ThunderX nic driver
would use something like the following in files.arm64:

arm64/cavium/thunder_nic.c optional soc_cavm_thunderx thndr_nic

3b7f258a4d Allow the arm64 config file to define SOCDEV_PA and SOCDEV_VA that may be 
used in locore.S to map an extra range when enabling the MMU.

e5acd89c78 Bring in the start of the arm64 kernel. 
This is only the minimum set of files needed to boot in qemu. As such it is
missing a few things.

The bus_dma code is currently only stub functions with a full implementation
from the development tree to follow.

The gic driver has been copied as the interrupt framework is different. It
is expected the two drivers will be merged by the arm intrng project,
however this will need to be imported into the tree and support for arm64
would need to be added.

This includes code developed by myself, SemiHalf, Ed Maste, and Robin
Randhawa from ARM. This has been funded by the FreeBSD Foundation, with
early development by myself in my spare time with assistance from Robin.
