In the EFI implementation in U-Boot no ConOut efi variable is created,
this cause loader to fallback to TERM_EMU implementation which is very
very very slow (and uses the ConOut device in the system table anyway).
The UEFI spec aren't clear as if this variable needs to exists or not.

In case of efi console having serial backend (video + serial or only serial),
we need to stick with old emulator till we can draw console.
Eventually we would need to get console terminal emulator to be removed
from serial console because the serial link already has the terminal.
However, we need to implement comconsole on all efi platforms first, then
we need the ability to draw console, so we do not have to use SimpleTextOutput
protocol (which will write both on video and serial in case of multiplexed
ComOut).

Actual modules get require()'d in, rather than try_include(). All instances
of try_include should be provided with proper hooks/API in the rest of
loader to do the work they need to do, since we can't rely on them to exist.
Convert this now to lfs + dofile since we won't really be treating them as
modules.
lfs is required because dofile will properly throw an error if the file
doesn't exist, which is not in the spirit of 'optionally included'.
Getting out of the pcall game allows us to provide a loader.exit() style
call that backs out to the common bits of loader (autoboot sequence unless
disabled with a loader.setenv("autoboot_delay", "NO")). The most ideal way
identified so far to implement loader.exit() is to throw a special
abort-style error that indicates to the caller in interp_lua that we've not
actually errored out, just continue execution. Otherwise, we have to hack in
logic to bubble up and return from loader.lua without continuing further,
which gets kind of ugly depending on the context in which we're aborting.
A compat shim is provided temporarily in case the executing loader doesn't
yet have loader.lua_path, which was just added in r354246.
As described previously, loader.lua_path is absolute path where scripts are
installed. A future commit will use this to build paths for dofile in
try_include, rather than the current pcall/require setup that makes it more
difficult to coordinate loader aborts from local.lua -- we do not need the
flexibility of require(), and local.lua is in-fact not a 'module-like' file
as we will not be referencing anything from it.
Multiple places coordinate to 'know' where lua scripts are installed. Knock
this down to being formally defined (and overridable) in exactly one spot,
defs.mk, and spread the knowledge to loaders and liblua alike. A future
commit will expose this to lua as loader.lua_path, so it can build absolute
paths to lua scripts as needed.

Previously color.disabled would be calculated at color module load time,
then never touched again. We can detect serial boots beyond just what we're
told by loader.conf(5) so this works out in many cases, but we must
re-evaluate the situation after the config is loaded to make sure we're not
supposed to be forcing it enabled/disabled.
Discovered while trying to test r353872.
When colors are disabled, color.escape{fg,bg} would return the passed in
color rather than the proper ANSI sequence for the color.
color.escape{fg,bg} would be wrong.
Instead return '', as the associated reset* functions will also return ''.
This should get rid of the funky '2' and '4' in the kernel selector if
you're booting serial.

This was committed due to what was later diagnosed as an msdosfs bug
preventing in-place strip. This bug was fixed in r352564, and we agreed to
keep the workaround in for a bit to allow the driver fix a suitable amount
of propagation time for folks building/installing powerpc/ubldr, seeing as
how we were not in any hurry to revert.
Logic was backwards. The function returns true if it *is* running as a
hypervisor, whereas we want to only call the CAS utility if we're running as a
guest.

Since local UEFI console is implemented on top of framebuffer,
we need to avoid redrawing the whole screen ourselves, but let
Simple Text Mode to do the scroll for us.
Add settable variables to control teken default color attributes.
The supported colors are 0-7 or basic color names:
black, red, green, brown, blue, magenta, cyan, white.
The current implementation does add some duplication which will be addressed
later.
It's not uncommon these days for the terminals attached to serial consoles
to support ANSI escape sequences. However, we assume escape sequences may
break some serial consoles and default to not using them when boot_serial or
boot_multicons (or if console contains "comconsole" in the forth loader) for
broader compatibility. We also have loader_color which can be explicitly set
to "NO" to disable the use of ANSI escape sequences.
The problem is that loader_color=YES gets ignored when boot_serial=YES or
boot_multicons=YES (or when console contains "comconsole" in the forth
loader).
To fix, the existing default behavior remains unchanged when loader_color is
unset, loader_color=NO explicitly disables the use of ANSI escape sequences
still, and the change is that loader_color=YES can now be used to explicitly
allow ANSI escapes when a serial console is enabled.

Summary:
Install's strip capability, by way of strip(1), doesn't seem to work
correctly on msdosfs, and instead ends up truncating the resulting
binary to 0-length. As a workaround, don't strip ubldr(8). This
fixes installworld on Book-E ubldr-based platforms, which prior to this
would need to manually install ubldr separately after installworld, in
order to have a functional ubldr.
The same thing could be done on PowerNV platforms that use msdosfs /boot
volumes, since loader and loader.kboot, etc, all get truncated to 0 on
install. However, PowerNV does not use loader, instead loading from
petitboot, so it's not really necessary at this time.

BFD appears to silently truncate 0xffffffff80800000 when it processes the
ldscript for 32-bit mips, but LLD chokes on it as the linker script tries to

is kosher or not and whether this patch is really what we want to do, but it
is one approach at least.

UEFI specification 2.7A, EFI_BLOCK_IO_PROTOCOL, page 566.
The ioalign property does define the alignment of data buffer.
If the alignment is required and our buffer is not aligned, or if
the data buffer is not multiple of Blocksize, we need to use bounce buffer
to perform the block IO. This is much like with BIOS version, except
there the INT13 needs buffer to be located in low memory.
Additionally, we need to handle disk writes properly.
