and host1x module. Unfortunately, tegra124 SoC doesn't have 2D acceleration
engine and 3D requires not yet started nouveau driver.
These drivers forms a first non-x86 DRM2 enabled graphic stack.
Note, there are 2 outstanding issues:
- The code uses gross hack in order to be comply with
OBJT_MGTDEVICE pager. (See tegra_bo_init_pager() in tegra_bo.c)
- Due to improper(probably) refcounting in drm_gem_mmap_single()
(in drm_gem.c), the gem objects are never released.
I hope that I will be able to address both issues in finite time,
but I don't want to touch x86 world now.
MFC after: 1 month
All armv6 processors are plenty fast enough for HZ=1000.
No changes are made for older arm systems, because some chips are a bit
wimpy for 1000 while others do fine, so it has to be set on a per-config
basis.
so the module could be loaded.

This allow us to boot FreeBSD kernel (using uImage encapsulation) directly
from U-boot using 'bootm' command or by Android fastboot loader.
For now, kernel uImage must be marked as Linux, but we can add support for
FreeBSD into U-Boot later.
