- Add driver for TDA19988 HDMI framer
- Add simple interface to communicate with HDMI sink: read EDID and set videomode
- Add event-based API to notify LCD controller when HDMI sink is available
- Add HDMI framer node and add refernce to it to lcdc node. This part of
DTS tree is custom and does not match Linux DTS because Linux uses
combination of pseudo-node in DTS and hardcoded driver information
that does not map to our model.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

tv open 480p
mmc rescan 0
fatload mmc 0 0x80100000 kernel.bin

The current FreeBSD driver doesn't program the video
clocks so the u-boot tv command is necessary in order
for the frame buffer to be useful (otherwise it can
be skipped).
The SD card for the Yiyate Android TV Box doesn't need

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3
On Pandaboard serial console devices was changed from /dev/ttyu0 to

This is based on the patch sent by Alexander Fedorov with the following
fixes/improvements:
- Better error handling;
- Clock is derived from PLL6 (obtained from netbsd);
- No more unnecessary busy loops on interrupt handler;
- style(9) fixes and code cleanup.
I also want to thanks Martin Galvan who has sent an alternative
implementation with some interesting fixes.
Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1
(Pratik Singhal).
This is intended to pave the way for the upcoming GSoC work (and make
easier the build of images for the supported boards).

access and reopening it before the next (causing it to re-obtain network
params each time). This vastly speeds up netbooting.
it from the uboot net_init() implementation. The routine uses the standard
U-Boot env vars plus a freebsd-specific variable named "rootpath" (the
corresponding u-boot variable for that would be "bootfile" except that it
refers to ubldr, so a new name was needed to communicate the path to ubldr).
This allows ubldr to load a kernel from nfs without requiring a dhcp or
bootp server to provide the server ip and rootpath parameters.
than bootp and rarp.
The code which splits a serverip:/rootpath string into rootip and a plain
pathname is now a separate net_parse_rootpath() function that can be
called by others. The code that sets the kernel env vars needed for
nfs_diskless is moved into net_open() so that the variables get set no
matter where the params came from.
There was already code in net_open() that allowed for the possibility that
some other entity has set up the network-related global variables. It uses
the rootip variable as the key, assuming that if it is set all the other
required variables are set too. These changes don't alter the existing
behavior, they just make it easier to actually write some new code to get
the params from another source (such as the U-Boot environment).
Previously, ubldr would use the virtual addresses in the elf headers by
masking off the high bits and assuming the result was a physical address
where the kernel should be loaded. That would sometimes discard
significant bits of the physical address, but the effects of that were
undone by archsw copy code that would find a large block of memory and
apply an offset to the source/dest copy addresses. The result was that
things were loaded at a different physical address than requested by the
higher code layers, but that worked because other adjustments were applied
later (such as when jumping to the entry point). Very confusing, and
somewhat fragile.
Now the archsw copy routines are just simple copies, and instead
archsw.arch_loadaddr is implemented to choose a load address. The new
routine uses some of the code from the old offset-translation routine to
find the largest block of ram, but it excludes ubldr itself from that
range, and also excludes If ubldr splits the largest block of ram in
two, the kernel is loaded into the bottom of whichever resulting block is
larger.
As part of eliminating ubldr itself from the ram ranges, export the heap
start/end addresses in a pair of new global variables.
This change means that the virtual addresses in the arm kernel elf headers
now have no meaning at all, except for the entry point address. There is
an implicit assumption that the entry point is in the first text page, and
that the address in the the header can be turned into an offset by masking
it with PAGE_MASK. In the future we can link all arm kernels at a virtual
address of 0xC0000000 with no need to use any low-order part of the
address to influence where in ram the kernel gets loaded.

Despite what I said in my prior commit, it turns out this one platform
was checking the return value from the old self-reloc code (which returned
a hard-coded 0).
The function was defined as taking 4 parameters and returning EFI_STATUS,
but all existing callers (in asm code) passed only two parameters and don't
use the return value. The function signature now matches that usage, and
doesn't refer to efi-specific types.
Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.
The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.

loaded at boot time via the provided example in loader.conf. The tunable
'vm.blacklist' remains, but using an external file means that there's no
practical limit to the size of the list. This change also improves the
scanning algorithm for processing the list, scanning the list only once
instead of scanning it for every page in the system. Both the sysctl and
the file can be unsorted and contain duplicates so long as each entry is
numeric (decimal or hex) and is separated by a space, comma, or newline
character. The sysctl 'vm.page_blacklist' is now provided to report what
memory locations were successfully excluded.
