9abece3985 video: rockchip: Support 4K resolution for rk3288, HDMI
Like, rk3399 the rk3288 also supports 4K resolution.

So, enable it for rk3288 with HDMI platforms.

Right now, rockchip video drivers are supporting for rk3288,
rk3399 SoC families, so mark the 4K resolution by default
if it's an HDMI video out.

This exercises a few success and failure modes of the log filter-*

3e40976aba cmd: log: Add commands to manipulate filters
This adds several commands to add, list, and remove log filters. Due to the
complexity of adding a filter, `log filter-list` uses options instead of
positional arguments.

These commands have been added as subcommands to log by using a dash to
join the subcommand and subsubcommand. This is stylistic, and they could be
converted to proper subsubcommands if it is wished.

72eda5074b lib: Add getopt
Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.

This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.

The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?

I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

62ef81891d test: log: Convert log_test from python to C
When rebasing this series I had to renumber all my log tests because
someone made another log test in the meantime. This involved updaing a
number in several places (C and python), and it wasn't checked by the
compiler. So I though "how hard could it be to just rewrite in C?" And
though it wasn't hard, it *was* tedious. Tests are numbered the same as
before to allow for easier review.

A note that if a test fails, everything after it will probably also fail.
This is because that test won't clean up its filters.  There's no easy way
to do the cleanup, except perhaps removing all filters in a wrapper
function.

fe3b1a2d21 log: Add filter flag to deny on match
Without this flag, log filters can only explicitly accept messages.
Allowing denial makes it easier to filter certain subsystems. Unlike
allow-ing filters, deny-ing filters are added to the beginning of the
filter list. This should do the Right Thing most of the time, but it's
less-universal than allowing filters to be inserted anywhere. If this
becomes a problem, then perhaps log_filter_add* should take a filter number
to insert before/after.

fb71c3f490 rtc: initialize emulated RTC from environment variable
Up to now the emulated RTC is initialized using the U-Boot build time.

With this patch the environment variable 'rtc_emul_epoch' can be used to
provide a better initial time. The variable is a decimal string with
the number of seconds since 1970-01-01. Here is an example where the RTC
had not been probed yet:

    => setenv rtc_emul_epoch 1610109000
    => date
    Date: 2021-01-08 (Friday)    Time: 12:30:00

If the variable does not exist, the U-Boot build time is used as fallback.

The environment variable may be set when shutting down the operating system
if the U-Boot environment is exposed to the OS (cf. ENV_IS_IN_FAT and
ENV_IS_IN_EXT4).

da0be4e176 clk: rockchip: rk3399: implement getting wdt/alive clocks
In order to correctly calculate the designware watchdog
timeouts, the watchdog clock is required. Implement required
clocks to facilitate this.

2424057b2a binman: Avoid calculated section data repeatedly
Refactor the implementation slightly so that section data is not
rebuilt when it is already available.

We still have GetData() set up to rebuild the section, since we don't
currently track when things change that might affect a section. For
example, if a blob is updated within a section, we must rebuild it.
Tracking that would be possible but is more complex, so it left for
another time.

8f5ef89f00 binman: Support compression of sections
With the previous changes, it is now possible to compress entire
sections. Add some tests to check that compression works correctly,
including updating the metadata.

Also update the documentation.

0ff83da634 binman: Use the actual contents in CheckSize()
At present this function adds up the total size of entries to work out the
size of a section's contents. With compression this is no-longer enough.

We may as well bite the bullet and build the section contents instead.
Call _BuildSectionData() to get the (possibly compressed) contents and
GetPaddedData() to get the same but with padding added.

Note that this is inefficient since the section contents is calculated
twice. Future work will improve this.

This affects testPackOverlapMap() since the error is reported with a
different section size now (enough to hold the contents). Update that at
the same time.
