3 years agox86: fsp: Adjust calculations for MTRR range and DRAM top
Simon Glass [Wed, 4 Nov 2020 16:57:43 +0000 (09:57 -0700)]
x86: fsp: Adjust calculations for MTRR range and DRAM top

At present the top of available DRAM is the same as the top of the range
of the low-memory MTRR.

In fact, U-Boot is allowed to use memory up until the start of the FSP
reserved memory. Use that value for low_end, since it makes more memory
available.

Keep the same calculation as before for mtrr_top, i.e. the top of
reserved memory.

A side-effect of this change is that the E820 tables have a single entry
that extends from the bottom of the memory used by U-Boot to the bottom
of the FSP reserved memory. This includes the bloblist, if ACPI tables
are placed there.

Michael wrote:
commit 92765f45bb95 ("env: Access Environment in SPI flashes before

breaks others which use a (late) SPI environment.

reason is, that env_init() sets the init bit, if there
is no init function defined in an environment driver,
and use default return value -ENOENT in this case
later for setting the default environment.

Change:
Environment driver can now implement an init
function and return, if this function does nothing,
simply -ENOENT.

env_init() now handles -ENOENT correct by setting the
inited bit for the environment driver. And if there
is no other environment driver whose init function
returns 0, load than the default environment.

This prevents that each environment driver needs to set the
default environment.

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.
