and add support for default underride to $loader_version, acting as a way to
name a release. Release text is not displayed for the aforementioned feature
of alternate display layout (introduced in r254237); however, for all other
layouts (incl. default), the release name is displayed at lower-right.
See version.4th(8) for additional information and/or historical details.
NOTE: Also a minor edit to version.4th(8) while we're here.
The TI uart hardware is ns16550-compatible, except that before it can
be used the clocks and power have to be enabled and a non-standard
mode control register has to be set to put the device in uart mode
(as opposed to irDa or other serial protocols). This adds the extra
code in an extension to the standard ns8250 probe routine, and the
rest of the driver is just the standard ns8250 code.
The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.
This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.
This initial incarnation lacks DMA support (coming soon). Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.
Add support for A20 timer.
Correct interrupt offset depending from chip.
Add basic code for CPU configuration module.
For now, add kernel config and dts file
(only FDT blob related problem needs to be solved later in
order to have one kernel for both cubieboard1 and 2).

being defined in <sys/diskmbr.h>. Instead give the symbols here a
"PC98_" prefix. This way, both <sys/diskmbr.h> and <sys/diskpc98.h>
can be included in the same C source file.
The renaming is trivial. The only gotcha is that DOSBBSECTOR is
also redefined from 0 to 1. This because DOSBBSECTOR was always
used in conjunction with an addition of 1. The PC98_BBSECTOR symbol
is defined as 1 and the expression is simplified.
Note: it is not believed that ports are seriously impacted; or at
all for that matter.

interpreter that can be run on the system and as such cannot be
compiled against libbstand. On the one hand this means we need to
include the usual headers for system interfaces that we use and
on the the other hand we can only use standard system interfaces.
While here, define local variables only when needed to make this

isdir? ( fd -- bool )
freaddir ( fd -- ptr len TRUE | FALSE )
The 'isdir?' word returns `true' if the file descriptor is for a
directory and `false' otherwise.
The 'freaddir' word reads the next directory entry and if successful,
returns its name and 'true'. Otherwise 'false' is returned.
These words give the loader the ability to scan directories and read
files contained in them for 'rc.d'-like flexibility in handling which
modules to load and/or which tunables to set.

when booting from ZFS turned out to also cause the boot path not being
adjusted if booting from CD-ROM with firmware versions that do not employ
the "cdrom" alias in that case. So shuffle the code around instead in order
to achieve the original intent. Ideally, we shouldn't fiddle with the boot
path when booting from UFS on a disk either; unfortunately, there doesn't
seem to be an universal way of telling disks and CD-ROMs apart, though. [1]

In some virtual environments (VMware, VirtualBox, etc) this could lead

so we need explicit casts to long and unsigned long here to ensure
that the result matches the printf %ld and %lx specifiers.
they can easily be used by later post-processing. When searching for
a compiled-in fdt blob, use the section headers to get the size and
location of the .dynsym section to do a symbol search.
This fixes a problem where the search could overshoot the symbol
table and wander into the string table. Sometimes that was harmless
and sometimes it lead to spurious panic messages about an offset
bigger than the module size.
elf headers, mask out the high nibble of that address. This effectly makes
the entry point the offset from the load address, and it gets adjusted for
the actual load address before jumping to it.
Masking the high nibble makes assumptions about memory layout that are true
for all the arm platforms we support right now, but it makes me uneasy.
This needs to be revisited.
