Depending on MMU presence in CPU there're differences in HW behavior.
For example address of instruction that caused exception is put in
ECR register if MMU exists and in ERET register otherwise.

To disable interrupts we need to reset corresponding flags in STATUS32
register. For this we need to OR flags for interrupts level1 and level2
and then AND with current value in STATUS32.
Before that implementation was incorrect.

Some cache operations ({i|d}cache_{enable|disable|status} or
flush_dcache_all) are built and used even if CONFIG_SYS_{I|D}CACHE_OFF
is set.
This is required for force disable of caches on early boot.
What if something was executed before U-boot and enabled caches
(low-level bootloaders, previously run kernel etc.)?
But if CPU doesn't really have caches any attempt to access
cache-related AUX registers triggers instruction error exception.
So for convenience we'll try to avoid exceptions by checking if CPU
actually has caches (we check separately data and instruction cache
existence) at all.

Normally buildman runs with 'make -s' meaning that only errors and warnings
appear in the log file. Add a -V option to run make in verbose mode, and
with V=1, causing a full build log to be created.

The site at https://www.kernel.org/pub/tools/crosstool/ is a convenient
repository of toolchains which can be used for U-Boot. Add a feature to
download and install a toolchain for a selected architecture automatically.
It isn't clear how long this site will stay in the current place and
format, but we should be able to rely on bug reports if it changes.

In some cases there may be multiple toolchains with the same name in the

Note: Wolfgang mentioned that this is dangerous since in some cases there
may be other tools on the path that are needed. So this is set up as an
option, not the default. I will need test confirmation (i.e. that this

If:
1. Toolchains A and B have the same filename
2. Toolchain A is in the PATH
3. Toolchain B is given in ~/.buildman and buildman uses it to build
then buildman will add toolchain B to the end of its path but will not
necessarily use it since U-Boot will find toolchain A first in the PATH.
Try to fix this by putting the toolchain first in the path instead of
last.

Buildman normally obtains the upstream commit by asking git. Provided that
the branch was created with 'git checkout -b <branch> <some_upstream>' then
this normally works.
When there is no upstream, we can try to guess one, by looking up through
the commits until we find a branch. Add a function to try this and print
a warning if buildman ends up relying on it.
Also update the documentation to match.

It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig"
instead of "include/configs/xxx.h" because then header will be reusable
across boards with different CPU clocks.
Also this nice to have an ability for end user to tune this value
himself via "menuconfig".
For now I'm only applying this change to all ARC configs because
otherwise scope of change will be huge.

Commit 4d3b8a0d fixed a problem with lzma decompress where it would
run out of bytes to decompress. The algorithm needs to know how many
uncompressed bytes it is expected to produce.
However, the fix introduced a potential buffer overrun, and causes
the compression test to fail (test_compression command in sandbox).
The correct fix seems to be to use the minimum of the expected number
of uncompressed bytes and the amount of output space available. That
way things work normally when there is enough space, and return an
error (without overrunning available space) when there is not.
